Opis:
During the last two decades of the 20th century and first years of the 21st century more intensive karst processes have been witnessed in North Lithuania. The intensity of the karst process is visible as new sinkholes appearing that severely damage crops, constructions and communication systems. Explanation and forecast of these hazardous phenomena requires knowledge based on systematic monitoring data and adequate interpretation with identification of relevant geoindicators of the intensive sulphate karst processes which are of primary significance for environmental planning and management of the region. Two geoindicators, gypsum chemical denudation and the intensity of appearance of new sinkholes, were selected for monitoring of karst processes in North Lithuania. Chemical denudation has been measured since 1964 in this region. These geoindicators show that since 1978 the intensity of karst denudation has increased by 30%, with more frequent formation of sinkholes. A correlation of this phenomenon with climate change — increasing air temperature and decreasing of the duration of seasonally frozen ground — is proposed and discussed in this paper.

Zoloushka Cave
Opis:
The Zoloushka Cave, with passages >90 km long and a volume of ~0.65 million m3, is among the largest gypsum caves in the world. The cave was opened in the course of gypsum excavation in a quarry in the village of Criva (Moldova) located just near the border with Ukraine. During the quarry exploitation, with the accompanying pumping of water, the groundwater table was lowered to the bottom part of the gypsum layer. As a result of the pumping, the karst aquifer within the cave labyrinth was fragmented into separate underground reservoirs controlled by the morphology of the karst system and its content of clay deposits. Currently, there are several dozen lakes in the cave with a varied hydrodynamic regime (relict lakes, lakes with direct and indirect hydraulic connection with the aquifer). Research was carried out in February 2020 to determine the degree of, and reasons for, the hydrogeochemical diversity of 10 selected lakes of various hydrodynamic types present in the cave. The degree of variability of the hydrogeochemical parameters of these lakes was found to depend on a number of factors, mainly: the hydrodynamic type of the cave lake resulting from the degree of its hydraulic connection with the aquifer; the geochemical environment of the lake; and anthropogenic influence. The autonomizing role of these factors is the modification (within individual lakes) of the hydrogeochemical context of the transit waters flowing through the cave system to the quarry.

Opis:
Areas of tropical karst create the most spectacular earth landscapes from a geomorphological perspective. These areas are characterized by a variety of specific forms resulting from the long-term karst-erosion dismemberment of terrains in favourable humid tropical conditions. Tropical karst areas are extremely diverse from a geomorphological point of view both in terms of local conditions of development and developmental stages. Among the many types of karst relief, the following two basic types can be recognized: fenglin (tower karst) and fengcong (cone karst). The other types can be treated as a mixture of these two basic types. To find potential quantitative rates characterizing the two main types, as well as the mixed types, we calculated fractal dimensions and cover factors of 17 areas located within the two well-known regions of South China Karst - Guilin and Huanjiang. The calculations show that the numerical characteristics obtained, especially the cover factor parameter, can be useful as complementary tools in the recognition and typology of tropical karst relief and landscapes.

Opis:
Obszary krasowe, w tym krajobrazy krasowe cechuje wyraźna odrębność środowiskowa. Polega ona na tym, że ze względu na rozwój podziemnych kanałów i próżni oraz ich interakcje z powierzchnią, obszary krasowe nabywają specyficznych cech (suche, bezwodne, czasami kamieniste, usiane lejami krasowymi, o specyficznej roślinności, glebach itp.), wyróżniających je – bez względu na strefy klimatyczne – spośród innych krajobrazów w postaci niejakich „wysp”. Zjawisko wyspowości dostrzec można również w strukturze wewnętrznej krajobrazów krasowych. Wyraźnie wyspowy charakter mają zarówno wklęsłe (leje, zapadliska, kotliny, polja) jak i wypukle (pojedyncze pagóry, ostańce) geokompleksy, występujące wewnątrz krajobrazu. Specyficzny wyspowy charakter mają też odrębne utwory krasowe, takie jak: senote, tiankeng, mogote, tepui itp. W ich obrębie tworzą się „zaginione światy”, refugia biotyczne, ośrodki o wzmożonej bioróżnorodności, co nadaje im wyjątkowych wartości przyrodoochronnych. Szczególny typ wyspowości krajobrazu krasowego stanowią tzw. archipelagi krasowe, rozpowszechnione w przybrzeżnej strefie obszarów krasu tropikalnego typu fenglin, zatopionych w holocenie wskutek transgresji morza.
Karst areas, including karst landscapes, differ by highly distinct environment. It consists in the fact that due to the development of underground channels and cavities and their interaction with the surface, karst areas acquire specific characteristics (dry, waterless, sometimes rocky, dotted with karst dolines and sinkholes, with a specific vegetation, soils, etc.), distinguishing them - without due to the climatic or plant zones – from other landscapes in the form of certain "islands". The phenomenon of insularity can be seen also in the internal structure of karst landscapes. Clearly insular character are both concave (dolines, sinkholes, depressions, polja) and convex (single hills, karst towers) geokomplexes occurring within the landscape. The specific insular nature are also distinct karst formations such as senote, tiankeng, mogote, tepui etc. "Lost worlds", biotic refugias, centres with increased biodiversity, which gives them exceptional nature-protection values, created within them. The particular type of insularity of karst landscape are the so-called karst archipelagos widespread in the coastal zone of tropical karst areas of fenglin type, submerged due to Holocene transgression.

The Moravian Karst in the south-eastern part of the Czech Republic has considerable potential for the development of geotourism. It is characterized by outstanding geodiversity, revealed in abundant, surface and subterranean karst landforms, as well as protracted history of karst evolution which can be traced back to the Mesozoic. An additional value is provided by the presence of cultural heritage, related to exploitation and processing of mineral resources genetically linked to the karst environment. The significance of this area is further enhanced by easy access to karst landforms and phenomena. Five caves, each of different morphology, can be visited. A dense network of educational trails, marked paths, forestry and field-access roads allows the visitor to reach all interesting features of karst morphology.
Kras Morawski w południowo-wschodniej części Republiki Czeskiej jest obszarem o bardzo dużym potencjale geoturystycznym. Cechuje go znaczna georóżnorodność, wyrażająca się bogactwem form krasu powierzchniowego i podziemnego oraz złożoną historią ewolucji krasu, sięgającą ery mezozoicznej. Elementem dodatkowym są liczne obiekty dziedzictwa kulturowego, związane z eksploatacją i przeróbką surowców mineralnych genetycznie związanych ze środowiskiem krasowym. O randze obszaru decyduje także bardzo dobre udostępnienie form rzeźby krasowej. Do zwiedzania jest przystosowanych pięć jaskiń o odmiennej morfologii, wytyczono kilka ścieżek edukacyjnych, a gęsta sieć znakowanych szlaków, dróg leśnych i polnych pozwala na dotarcie do wszystkich interesujących form powierzchniowych.

Opis:
The mid-altitude mountain massif of Mali me Gropa is located in the central part of Albania, rises to an altitude of 1500–1800 m a.s.l., is composed mostly of Mesozoic limestone, and is characterized by extensive surface karst development. The karst relief is dominated by “doline” morphology including “polygonal” karst. Detailed geomorphological analysis of the western part of the Mali me Gropa massif (so-called Western Massif) by means of GIS methods is used to determine and explain the morphometric and morphological diversity of the area’s topography. Based on a homogeneity criterion, a number of geomorphological units with specific kinds of karst relief have been distinguished within the massif. The differences in karst sculpture concern the size (diameter) of dolines and depressions, their depth, shape and symmetry, orientation, density of occurrence and spatial pattern, which provide the basis for distinguishing geomorphological units. The spatial differentiation of the karst relief is explained by the influence of factors which are evolutionary (geological and geomorphological evolution of the massif), hypsometric (altitude difference of terrains) and geomorphologic-structural (inclination of the slopes and layers). The relatively poor expression of open karst conduits (i.e. caves and vertical shafts) on the surface of the massif may result from the relative immaturity of the epikarst zone, the widespread occurrence of residual cover on the plateau, and the accumulation of large amounts of clay material in dolines and depressions. Detailed hydrogeological studies show, however, high karst permeability and dominance of conduit flow. Considering the high geomorphological landscape and ecological value of the area, it should be granted the status of a nature reserve or national park. Geomorphological and karstological research within the massif should be continued as it represents a type of karst found also in other parts of Albania. This type of karst area is of great economic (groundwater reserves) and natural protection (environmental) importance.

The genus Dipoides and the species Trogontherium (Euroxenomys) minus have not previously been reported from Poland. Their presence at the Węże 2 site suggests that these lesser-known and extinct representatives of the Castoridae were adapted to similar conditions as the modern species (Castor fiber and C. canadensis).

The crystallization of speleothems can be interrupted by the invasion of allogenic water into cave passages. These interruptions were studied, both in speleothems currently submerged in an underground river and in speleothem sections, which were found at the lowermost fluvially active passage level of the Demänová Cave System. The interaction between speleothems and allogenic water, undersaturated with respect to calcite, is manifested in the presence of siliciclastic material and the corrosion of calcite crystals. The progressive development of corrosion features depends on the duration of the interaction of calcite crystals with allogenic water. Moreover, the movement of the water and siliciclastic deposition over the speleothems can influence the corrosion process. The estimated rate of corrosion, caused by the underground Demänovka River and measured by the weight loss of experimental tablets, is up to 0.029 mm/y. U-series dating indicated that the interaction of speleothems with allogenic water occurred during the Vistulian (Weichselian). The identification of corrosion episodes, caused by allogenic water, is a step towards understanding the origin of hiatuses and establishing criteria for recognition of them.

The goal of this project, implemented in 2012– 2015, is to establish the first karst aquifer world map, presenting karst aquifers, most important water intakes, karst springs and caves. Selection criteria of the karstic objects were discussed in the paper. Database, created on their basis covering the area of Poland, includes: 17 water intakes (extracting mainly from the Triassic carbonate aquifer of Silesian – Kraków monocline), 7 springs (including 5 vaucluses from Tatra Mountains), 23 caves (located mainly in Western Tatra Mountains and in Kraków – Wieluń Upland). There is a probability of location of individual hydrogeological objects from Poland on the world karst aquifer map considering the importance of the region.

Opis:
One of the most up to date scientific problems in recognition of karst processes is quantitave evaluation their activity. Basic and distinctive indicators that describe karst processes activity are intensity and magnitude of chemical denudation (Aksiom S.D., 2002). Not only a tool for describing changes taking place in the observed hydrogeological system will be presented in the paper but tools that allow to predict changes that may take place on the spur of the natural and anthropogenic factors. Only a few methods widely used in hydrogeology are also used in geography. In this paper authors present basis of geochemical modeling that can be widely used. Geochemical modeling can be divided into two main issues: Measurement, assessment and generalization of kinetic and thermodynamic data for solid phases (e.g. minerals), gases and solutions; Use of above data in numerical algorithms describing natural and anthropogenicly changed systems of interaction between water and matrix (Macioszczyk, Dobrzyński, 2006). The practical aspects of geochemical modeling concentrate mainly on creating geochemical models of the environment and its changes. Geochemical modeling has been recently widely used for describing chemical composition of groundwater as well as factors and processes shaping it. A geochemical model is a tool that allow for understanding hydrogeochemical processes taking place in the environment. It is a basis for further analysis of system`s susceptibility for modifications conducted by human as well as it might be an element of the forecast of the risk of environment contamination. The main advantage of geochemical modeling is simplicity of received data interpretation, possibility of groundwater chemistry origin interpretation, predicting chemistry modifications and also forecasting changes in water quality. Geochemical models can be divided into three main groups: Speciation model – it doesn`t include any information about temporal or spatial distribution of processes, it only describe the effect of water – rock – gases interaction in a single point of hydrogeological space; Reaction path model – it delivers information about succeeding changes of the hydrogeological system (spatial variability) that take place as an effect of providing a load of mass and/or energy. The time effect can be modeled with use of reaction rate constant; Reactive transport model – it include data describing temporal and spatial variability of chemical reactions in the system.

Based on morphometric criteria, the diagnostic M1 and m1 speci mens are assignable to Glis mi nor and Glis sackdillingensis, two species which differ only in the dimensions of their cheek teeth. The presence of dormice at Węże 2 implies that the fossil assemblage of this site represents an at least partly wooded environment. The enamel structure in the glirids from Węże 2 is formed predomi nantly by radial enamel. A thin layer of lamellar enamel, occurring close to the enamel-dentine junction, may be present. Such a type of enamel structure is typical of the Myomorpha, the clade of rodents encompassing the Muroidea (the mouse-like rodents) and Gliridae.

Opis:
Ground Penetrating Radar (GPR) is one of the most effective and rapid types of geophysical survey methods. The present study was carried out in the Botanical Garden in Kielce, which is currently undergoing a second stage of infrastructure development. This object is located in the Świętokrzyskie (Holy Cross) Region, characterized by large scale deformations in the development of karst origins. Those structures threaten existing buildings and can be obstacles to newly constructed ones. Radargrams presented in this paper show significant potential of the GPR method in mapping of karst phenomena. Proper acquisition parameters and optimal processing of raw data resulted in a clear image of the structure of rock mass under the Botanical Garden, along acquired profile lines. Additionally, precise GPS coordinate links and established researchers’ experience of conducting this type of surveys helped in the process of mapping the anomalies in the limestone. Under these conditions, the survey minimized the need for a second method and resulted in high quality data acquisition. The study provided information about underlying rock mass structure development and registered anomalies whose origins include voids or caves of karst genesis. The area studied covers a large part of the Botanical Garden. Described anomalies can be dynamic in origin.

The Upper Jurassic aquifer, which is a Major Ground Water Basin (MGWB No 326), was delimited in this area. It is closely connected with surface waters including living biocenoses and other dependent from the state of water. At the area of the CCU exist several hundred springs. At the drainage areas of springs authors conducted interdisciplinary investigations, including hydrogeological, geochemical, geological studies performed in spring drainage areas. The communities of benthic invertebrates were determined as the biomarkers of the environmental state. In natural springs remarkable groups of species such as oligostenothermic, crenophilic or crenobiontic prevailed whereas in springs under anthropopression mainly eurybiontic species could be stated. Stygobiontic species were also found in a few springs. The study, done together with the recognition of regional land management and pollution sources, allow to estimate the influence of natural and anthropogenic factors on water environment and its biotic elements within the karstic area of the CCU.

Opis:
The Tatras are characterized by a high springability degree because of its considerable elevation above the surrounding Paleogene basins, deep cuttings in the massif by big river valleys and abundance of rainfall. The most common outflows are ftltration springs draining porous water of Quaternary deposits. Fissure springs which drain fissure water of crystalline core, lower Triassic quartzitic sandstones and sedimentary series with a smaller proportion of the carbonate rocks, are less numerous. The most productive outflows are springs and karst springs which are connected with the Tatra's carbonate sediments and, to a lesser degree, carbonate Eocene deposits (fig. l). The article includes the characteristics of these springs and karst springs which were monitored. Results of the stationary research, carried out since the 70s, showed that the dynamics and chemism of water drained by the Tatra's karst springs are decisively influenced by the location of the alimentation area. As far as the efficiency of outflows is concerned all the karst springs qualified for the III Meinzer's class. However, the karst springs can be divided into karst springs draining areas within orographic catchment basin of lower outputs between 3Q0-..400l/s (Chochołowskie and Bystre Springs) and those whose underground watersheds exceed orographic basin of the output between 500-700 Ifs (Lodowe, Goryczkowe, Olczyskie Springs). Carbonate Eocene is drained by the karst springs and springs of much lower outputs (IV and V Meinzer's class).

The phreatic paleoflow directions were analyse from the asymmetry of scallops. The paleoflow was directed from the east to the west, that is in a direction of the Kościeliska Valley. Therefore, this valley represented the main discharge zone of the region during the formation of Czarna Cave.

Opis:
The Dumre area, located in Central Albania, is distinguished by a landscape whose main features consist of low altitude, mosaic and irregular relief, and the presence of a large number of depressions with lakes. These features result from karst development related to the presence of a tectonically affected dome of Triassic evaporite rocks, mainly gypsum. Gypsum karstification has operated since the Pliocene, and the present-day geomorphological appearance of the area indicates an advanced, mature stage of karst development. Signs of this maturity include the widespread occurrence of large depressions, many of which are water-filled, forming lakes, the occasional presence of gypsum hills in the form of monadnocks, a thick “coating” of residual sediments largely isolating the karstic gypsum substrate from precipitation and surface waters, and the fragmentary pattern of a degraded river network. The karst character of the relief is largely “camouflaged” by clastic terrigenous and residual deposits of considerable thickness which cover the gypsum and form a caprock. At the present stage, the caprock is being strongly reshaped and eroded. Chemical analyses show a mean dissolved gypsum content of 1.9 g/l and mean dissolved NaCl content of 0.4 g/l. The mean flow rate of subaqueous springs is calculated as 1.84 m3. The density of gypsum is 2.3, and that of rock salt is 2.17, thus the total volume of gypsum dissolved each year is 47,420 m3 and of rock salt 10,680 m3, making a total volume of dissolved material released by the subaqueous springs in one year of 58,100 m3. This corresponds to a cubic void of side length 38.7 m.

The karst of northern Lithuania is developed in gypsiferous layers of the Pasvalys and Nemunelis beds of the Tatula Formation of the Upper Devonian (Frasnian) stage. The new sinkholes formed during the last ten years in around Birzai and Pasvalys indicate recent karst activity. 84 recent sinkholes appeared around the villages of Karajimiskis, Mantagailiskis in the Birzai district from 1995 to 1999. The three biggest sinkholes occur in Pasvalys. Karst processes and phenomena are particularly dangerous in urban areas. The sudden appearance of sinkholes and ground subsidence have often caused building damage. New sinkholes indicate a very sensitive engineering geological environment.

Opis:
The remediation of buildings with elevated radon concentrations is generally straightforward. However, in some cases a number of attempts may be needed to reduce concentrations to below the reference level and, occasionally, it may be impossible to reduce concentrations to below the reference level in a cost effective way. This paper details the work carried out between 2004 and 2012 to reduce radon concentrations in a house with initial radon concentrations of almost 1500 Bq/m3. Over this period, high radon levels were consistently recorded despite the introduction of various radon remedial measures. Remedial work was carried out on ten occasions with 29 radon tests carried out to measure the effect of this work. The paper describes the structure of the house and the karst geology that it is built on and the likely contribution of these factors to the difficulties encountered reducing concentrations. Ultimately, radon concentrations were reduced to about 450 Bq/m3 but no further reductions were considered practicable without substantial and costly renovation to the house. Nonetheless, the remedial work carried out to date has resulted in a significant reduction in the risk to the homeowner of developing lung cancer. This work has also added to the understanding of radon remediation techniques in Ireland, particularly for houses built on karst limestone.

Opis:
Karst evolution depends particularly on the time available for process evolution and on the geographical and geological conditions of the exposure of the rock. The longer the time, the higher the hydraulic gradient and the larger the amount of solvent water entering the karst system, the more evolved is the karst. In general, stratigraphic discontinuities directly influence the intensity and extent of karstification. Unconformities influence the stratigraphy of the karst through the time-span that is available for subaerial processes. The end of karstification can also be viewed from various perspectives. The definite end occurs at the moment when the host rock, together with its karst phenomena, has completely been eroded/denuded. Karst forms of individual evolution stages (cycles) can also be destroyed by erosion, denudation and abrasion without the necessity of the destruction of the whole succession of karst rocks. Temporary and/or final interruption of the karstification process can be caused by the “fossilisation” of the existing karst phenomena due to loss of hydrological activity. The shorter the time available for karstification, the greater is the likelihood that karst phenomena are pre-served in the stratigraphic record. While products of short-lived karstification on shallow carbonate platforms can be preserved by deposition during a immediately succeeding sea-level rise, products of more pronounced karstification can be destroyed by various geomorphological processes. The longer the duration of subaerial exposure, the more complex these geomorphological agents are.
Rozwój procesów krasowych jest funkcją czasu oraz geograficznych i geologicznych warunków odsłonięcia skał. Im dłuższy czas ekspozycji skał na czynniki meteorologiczne, większy gradient hydrauliczny, większa ilość wody w układzie krasowym, tym bardziej zaawansowana jest ewolucja krasu. Intensywność i zasięg krasowienia zależą też od niezgodności stratygraficznych, czyli przerw w sedymentacji. Zakończenie rozwoju procesów krasowych rozpatrywać można w różnych kategoriach. Za definitywny koniec należy uznać czas, gdy skały podlegające krasowieniu ulegną całkowitej denudacji/erozji. O wiele częściej bywa, że zniszczeniu ulegają tylko formy krasowe, natomiast niżej położone skały systemu krasowego pozostają zachowane. Okresowe lub całkowite przerwanie procesów krasowych może być spowodowane przez fosylizację systemu krasowego, która zachodzi w efekcie zaniku aktywności hydrologicznej. Taka fosylizacja może być spowodowana przez metamorfizm, transgresję morską, pogrzebanie osadami kontynentalnymi lub skałami wulkanicznymi, w wyniku np. ruchów tektonicznych, zmiany klimatu, itp. Im krótszy jest czas krasowienia, tym większe jest prawdopodobieństwo zachowania śladów procesów krasowych. I tak, produkty krótkookresowej karstyfikacji na płytkich, okresowo wynurzanych platformach węglanowych mogą ulegać łatwemu zachowaniu poprzez pogrzebanie osadami deponowanymi podczas podniesienia poziomu morza. Natomiast efekty długotrwałego krasowienia bywają często niszczone przez późniejsze degradacyjne procesy geomorfologiczne. Charakter tych ostatnich jest tym bardziej skomplikowany, im dłużej trwa subaeralna ekspozycja skrasowiałych skał.

Opis:
Słowacki Raj to jeden z najpiękniejszych regionów środkowej Europy. Do połowy trzeciorzędu była to lekko pofałdowana równina, z której sterczały niewysokie (do 100 metrów) wapienne pagóry, a rzeka Hornad, płynąca dzisiaj głębokim wąwozem, wiła się między tymi wzgórzami. Wtedy to nastąpiło wypiętrzenie dzisiejszego masywu Słowackiego Raju i jednocześnie zapadanie się kotliny Hornadu. Rzeki i potoki gwałtownie zwiększyły swoje spadki i rozcięły wapienno-dolomitowy masy kilkunastoma głębokimi wąwozami. W ekstremalnie wąskich kanionach utworzyły się na odpornych wapieniach płytowych i skalistych ogromne wodospady oraz niezwykłe skalne formy w postaci baszt, iglic, murów itp. Rzeka Hornad została „uwięziona” w obrębie odpornych skał wapiennych, rozcięła więc podłoże, tworząc niezwykle malowniczy przełom. Wody opadowe łatwo wnikają do wnętrza spękanego masywu, tworząc jeden z największych i najciekawszych systemów jaskiniowych na Słowacji, z jedyną w tej części Europy jaskinią lodową.
The Slovak Paradise is one of the most beautiful regions in Central Europe. Till the mid-Tertiary it was a slightly undulating plain, from which low (up to 100 meters) limestone mounds protruded, and the Hornád river, today flowing in deep gorge, meandered between these hills. At that time the uplift of the presentday massif of the Slovak Paradise and simultaneously the subsidence of the Hornád basin happened. Rivers and streams increased in their gradients violently and cut limestone-dolomite masses by many deep gorges. In extremely narrow canyons huge waterfalls and unusual rocky forms - towers, needles, walls etc. were shaped at resistant platy and massy limestones. The Hornád river was „trapped” within resistant limestone rocks and cut the substratum, forming the unusually picturesque gorge. Precipitation waters easily get in the interior of cracked massif, creating one of the largest and interesting cave systems in Slovakia, with ice cave - the one in this part of Europe.

The specific name velunensis is established to encompass porcupine remains (Hystrix Linnæus, 1758) recovered from the Pliocene site of Węże 1 in southern Poland. The studied specimen was previously assigned either to H. primigenia (Wagner, 1848) or H. depereti Sen, 2001, however it can be distinguished from these species and other fossil Hystricidae by its distinct occlusal morphology, most importantly the presence of an anterolingual flexus dissecting the anteroloph of P4. Hystrix velunensis sp. nov. was probably closely related to H. primigenia and H. depereti. A previously undescribed specimen from the nearby site of Węże 2 most probably belongs to H. refossa Gervais, 1852b, which would be the first known occurrence of this species in Poland.

The article describes the nature of the bedrock in areas in the Małopolska Upland where landforms associated with covered karst processes occur. It seeks to find a relationship between geological structure and the potential for covered karst processes to develop. To this end, it includes a review of the literature on the geological structure of three areas in the mesoregions of Wzgór-za Opoczyńskie, Niecka Włoszczowska and Niecka Solecka. Two of the three sites are located in an area of limestone karst, and the third (located in Niecka Solecka) is an area of gypsum karst. All three sites were filled with sediment in the Holocene, but the forms being studied probably formed much earlier. The author also attempts to reconstruct the relief of the Mesozoic surface as digital terrain models. For this purpose, data was taken from geological drillings contained in geological maps of Poland and developed using GIS software. According to digital terrain models in the form of 3D views all three investigated sites are locat-ed in a depressions in the Mesozoic surface (on the slopes or bottom of the basin). That location and low thickness of impervi-ous deposits has caused that migration of underground water, which can affect karstified rocks with increased intensity.

There are several springs with the large discharge around the Watuputih Karst Hills area that playing a crucial role in supplying water for both domestic and irrigation needs. The springs are located in the fault and fold zones of the Rembang anticlinorium system. This study was designed to determine the characteristics of karst aquifers from one year of monthly spatio-temporal data on discharge parameters and physico-chemical properties (temperature, pH, EC, Ca2+, Mg2+, HCO3–) of the four major springs, namely Brubulan Tahunan, Sumbersemen, Brubulan Pesucen, and Sendang Sayuran. It used statistical calculations to characterize spring discharge and hydrochemical variations, as well as bivariate correlation analysis and flow-duration curve (FDC). The variability index (Iv), variability (V), and spring coefficient of variation parameters (SCVP) classified Brubulan Tahunan and Sumbersemen as springs producing stable, fairly constant discharge with low variations but characterized Brubulan Pesucen as having unstable, varying discharge with moderate variations. The results showed gently sloping hydrograph, low variations in discharge and hydrochemical properties, a relatively prolonged response of discharge and CO2-H2O-CaCO3 interaction to rainfall, and slope changes in the FDC. In other terms, although the springs are controlled by faults and folds, they have diffuse groundwater storage system in the form of densely fractured and porous media. These findings also indicate a less developed interconnected conduit, although Brubulan Pesucen is relatively more developed than Sumbersemen and Brubulan Tahunan. The geological structure and hydraulic gradient formed between the groundwater recharge and discharge areas are proven to control the amount of spring discharge actively.

The first tetrapodomorph specimen from the Palaeozoic sequences of the Moravian Karst (Moravo-Silesian Basin, Bohemian Massif, Czech Republic) is described. The well preserved, cosmine-covered lateral extrascapular bone comes from the Upper Devonian (Famennian) hemipelagic Křtiny Limestone of the Líšeň Formation. The affinity to the “osteolepiforms” is inferred from the cosmine histology and morphological features of the bone. Assignment to the Megalichthyiformes seems most probable. The associated fauna, e.g., clymenids, orthocone nautiloids, thin shelled bivalves, trilobites and crinoids, clearly demonstrate a marine environment.

The negative landform of sinkholes provides belowground level refugia for a high diversity of forest species compared to the forests on the surface of surrounding karst plateaus in southeastern China. Bryophyte diversity in sinkhole forests is also likely to be high. In this study, bryophytes of an underground forest sinkhole (UFS), and two forests (Forest Karst Mountain 1; FKM1) and (Forest Karst Mountain 2; FKM2) on the surface of the karst plateau were compared to understand the role of the sinkhole forest in the conservation of bryophyte diversity and the relationships between bryophyte diversity, environmental factors, and soil nutrients. Significantly more bryophyte taxa were recorded from the sinkhole forest (71 taxa, 36 genera, 23 families) than those in the forest on the plateau surface, which was the closest to the sinkhole (FKM1; 29 bryophyte taxa, 16 genera, 12 families), and even fewer bryophytes were found in the forest more distant to the sinkhole (FKM2; 22 taxa, 17 genera, eight families). Twenty-four liverwort taxa were collected from the sinkhole forest, two from the closest surface forest (FKM1) and none from the furthest surface forest (FKM2). Ninety-three percent of the bryophytes in karst mountain sinkhole were not found on surface forest. The diversity index trend was as follows: UFS > FKM1 > FKM2, and the evenness index trend was in the opposite direction as follows: UFS < FKM1 < FKM2. The beta diversity showed that the Jaccard index among the three forests was 0–0.25, reflecting a huge difference between the sinkhole forest and the two surface forests. Canonical correspondence analysis showed that light was the most important factor affecting the distribution of bryophytes in the sinkhole forest, while temperature and humidity were key factors for the distribution of bryophytes in the two surface forests. Further, soil parameters, namely, soil organic carbon, total nitrogen, total phosphorus, total potassium, alkali- hydrolyzed nitrogen, and available phosphorus changed gradually from UFS to FKM1 and to FKM2. The sinkhole forest, located in a landform with the unique negative topography enclosed by cliffs, and with a complex microenvironment, provides a natural refuge for bryophyte species in areas where forests have been negatively impacted by karst rocky desertification.

Opis:
The Kraków-Wieluñ Upland is one of the major palaeokarst regions in Poland. However, the stages of karst development in this area are neither well documented nor reconstructed. A series of samples from a new location in the vicinity of Raciszyn was analysed. On the basis of the results of U-series dating, four phases of speleothem deposition were distinguished: (1) older than 600 ka, (2) from more than 600 ka to 290 ka, (3) around 150 ka, and the youngest (4), younger than 3 ka. On the basis of all geochronological data from the region, eight stages of karst development were described. The structure of the oldest speleothems indicates even more stages of deposition and erosion that cannot be recognized using the 230Th/234U dating method. These results indicate that the initial creation of empty spaces in the limestone took place in pre-Pleistocene time. After 600 ka ago, climatic conditions were stable for more than 300 ka, allowing the continuous deposition of speleothems. Several episodes of erosion, deposition of clastic sediments and speleothem growth during the Middle and Early Pleistocene were described. This variability of the sedimentation regime clearly reflects climate changes during that period.

Opis:
This paper demonstrates the evaluation of in trinsic vulnerability of karst-fissured waters in an Upper Jurassic aquifer by applying modified DRASTIC method. The area investigated is the Jura Krakowska (South Poland) - an area of upland merokarst (or relictkarst), where the Upper Jurassic aquifer is mainly unconfined. The method applied is a combination of a simulation model of the ground water aquifer (factors: netre charge, hydraulic conductivity, ground wa ter flow velocity in the aquifer) and a geographical in formation system - GIS model (depth of ground water table, lithology of vadosezone, thickness of Upper Jurassic aquifer), and additionally a soil factor was taken into account. In the area of the Jura Krakowska, 5 classes of intrinsic vulnerability to pollution were distinguished according to the values of vulnerability factors. These classes range from extremely high to low vulnerability (IP 200-50). Based on the synthetic map of vulnerability it emerges that high vulnerability indices cover 54% of the area studied while medium and low vulnerability indices cover 46% of this area. The modified DRASTIC method presented seems to be a useful tool to evaluate the intrinsic vulnerability of karst-fis sured aquifers of "Torcal" type with a scattered system of recharge and discharge, and a thick vadosezone of variable permeability. This is consistent with the method developed with European programme COST ACTION 620. All rating methods recommended for karst have limitations, there fore the method applied is constantly updated. Many of them are particularly use ful for areas of bare karst, mountain systems of "Aliou" type and in ar eas of complete karst develop ment (holokarst).

Opis:
A new locality of coarse-grained cryogenic cave carbonates has been found in the Za Hájovnou Cave in Javoříčko Karst in Central Moravia, Czech Republic. Crystals and crystal aggregates, usually up to 15 mm in size, form typical loose accumulations on the surface of large fallen limestone blocks and clays covering the bottoms of several cave chambers distant from the cave entrance. The cryogenic origin of the carbonates is supported by their mode of occurrence, specific crystal and aggregate morphology, and C and O stable isotope data. U-series dating of one sample of cryogenic carbonate (age 29.5 ±0.1 ka) indicated that a period of karst water freezing occurred in marine isotope stage (MIS) 3, within the Weichselian. The cave also hosts numerous examples of speleothem damage. As shown in this paper, some of these are clearly connected with freezing conditions and cave ice action.

Opis:
The Czerwone Wierchy Nappe is the main part of the Czerwone Wierchy Massif. Several big cave systems are developed in this structural unit, e.g., Wielka Śnieżna Cave System, Kozia, Ptasia, Mała w Mułowej and a lot of smaller caves. Cross-section I presents two main parts of Czerwone Wierchy Nappe-Organy and Idziary units which are separated by the Organy Dislocation. Similar structure is characteristic for whole Czerwone Wierchy Nappe (Kotański, 1963). The abundance of caves near Organy fault is a result of intensive tectonic processes in this area what is visible at the western slope of the Miętusia Valley. Further to the east , so far scientists (Kotański, 1961; Grodzicki & Kardaś, 1989) suggested that whole the Wielka Śnieżna Cave System is developed within the dziary Unit. Our geological cross-sections of the upper part of Miętusia Valley, (based on Grochocka-Rećko, 1963) show that only upper, vertical parts ofWielka Śnieżna and Śnieżna Studnia caves are developed in the dziary Unit, similarly as the upper, vertical part of the Mała Cave. Lower parts of cave systems are related to the Organy Dislocation and the Organy Unit. It seems that geological structure of the Czerwone Wierchy Massif is a dominant factor controlling the cave passages development. As a results of geological structure, the main path of water flow, at the level ca. 1000 m a.s.l., from lower parts of Wielka Śnieżna Cave in Miętusia Valley towards Lodowe Źródło in Kościeliska Valley developed solely along Middle Triassic layers in a latitudinal fold turn of the Organy Unit (Mała Łąka Fold, Kotański, 1961).

Opis:
The taxonomy of extinct species of Cuniculus (Caviomorpha, Rodentia, Mammalia) is confusing and poorly studied. Here we provide a taxonomic review of extinct cuniculids, and discuss the taxonomic, biogeographic, taphonomic and chronologic aspects of new remains of an extinct large cuniculid from Brazilian Quaternary Gruta Cuvieri cave deposits. Our taxonomic review suggests that Cuniculus rugiceps (Lund, 1837) is the valid taxon to include all available occurrences of extinct cuniculids. The most evident features of this taxon are its larger size and the stronger and more densely distributed rugosities on the skull external surface when compared to the extant species. At present, the distribution of C. rugiceps is restricted to the tropical region of Brazil. Regarding the new remains, taphonomic analysis of the specimens from Cuvieri Cave suggests our sample is represented by at least seven individuals that accumulated within the cave deposit by pitfall entrapment. The biostratinomy of the specimens was characterized by prolonged surface exposure inside the pit with fragmentation and displacement caused mostly by falling and subsequent trampling by individuals of the same and/or other species. The stratigraphically controlled excavations and chronological data allowed the establishment of a Late Pleistocene minimum age for these specimens.

The detailed gamma-ray and magnetic susceptibility patterns also provide promising clues which might help trace the "punctata Zone" stratigraphic equivalents, located far in the interior of the platform stromatoporoid-coral facies.

Study of four boreholes (each 100 mdeep) drilled in the St. Bronisława Hill (a part of the horst of the Wolski Forest, Kraków area) indicated that within the Oxfordian limestone occur claystones with calcareous rubble (detritus), filling the fossil karst forms. The claystones, that in some cases show planar stratification, contain assemblages of Late Cretaceous (Campanian–Maastrichtian) foraminifers. The Middle Miocene planar laminated limestones have also been found in cavities formed in the Middle Oxfordian limestones. Miocene deposits of this type, filling the fossil karst, were not previously known from the area of Kraków. Both the Upper Cretaceous and the Middle Miocene deposits document probably marine sedimentation that resulted in the filling of the karst system. This type of karst was probably formed before the transgression of the Upper Cretaceous sea and the subsequently before the transgression of the Middle Miocene sea into the area of present horst of the Wolski Forest.

Opis:
The Atlas of Beni Mellal is located in the Moroccan central High Atlas, characterized by an important geo-di-versity that attracts tourists every year. However, the number of visitors remains limited due to the lack of the promo-tion means, enhancement and mediation of this heritage. The obtained data indicate that the studied area preserves a great number of karst geosites, such as ruiniform landscapes, caves, poljes, sinkholes, Karren, shaft cave and many remarkable reliefs such as canyons and cliffs. This work concerns the inventory, the quantitative evaluation and the en-hancement of the remarkable geomorphosites. The results reveal the presence of 21 sites, including six karst forms; five ruiniform landscapes and one karren form, one enviable panoramic viewpoint and five karst springs, four caves, two travertines, two waterfalls, and one structural relief geosite; canyon, and one tepee structures. However, these sites are not protected against all types of degradation, because the general public does not recognize them. These karst forms are very vulnerable, they cannot reproduce quickly, and their deterioration leads to their permanent disappearance. That is why this heritage must be the object of a particular attention of the whole community. The valorisation of these geomorphologic assets is the proposal of a number of circuits and geotourist routes from the perspective of local and integrated development.

Opis:
The objective of this paper is a review of data on reconstruction of the Pleistocene palaeogeography (environment) and stratigraphy based on studies of karst sites in the Świętokrzyskie (Holy Cross) Mountains. Although the number of known Pleistocene karst sites in this region is small, the investigations of them have played a crucial role in a research of the Pleistocene. The study of the Kozi Grzbiet site provided the first evidences for new climatostratigraphy and classification of glaciations in Poland. The explanation of genesis of cryogenic calcite crystals discovered in Chelosiowa Jama-Jaskinia Jaworznicka cave system started a new direction of palaeoenvironmental reconstructions of the last glacial period. Kadzielnia palaeontological site was one of the first Early Pleistocene fossil assemblages in karst studied in Poland, whereas Raj cave provided abundant palaeontological and archaeological material from the Last Glacial. Other sites are of less scientific importance, however some of them can be used in education and popularisation of geosciences. Small number of already studied sites does not exclude discoveries of next sites of high scientific importance.

These local factors markedly affect regional environmental trends determined primarily by climate change and, during the last several hundred years, also by human activity. Such malacological analysis enables effective palaeogeographical reconstructions, both on the scale of geographical regions and for microhabitats.

Przedstawiono środowisko hydrogeologiczne krasu gipsowego w rejonie jaskini Zołuszka (pogranicze Ukrainy i Mołdawii). Celem badań wykonanych w lipcu 2008 r. było określenie chemizmu wód jezior jaskiniowych. Stwierdzono, że kształtuje się on w środowisku hydrogeochemicznym przejściowym. W ramach modelowania geochemicznego określono specjacje składników roztworu wodnego o wielkości wskaźnika nasycenia (SI) roztworu względem wybranych faz mineralnych. Chemizm wód został zrównoważony ze stężeniami O2 i CO2 w powietrzu jaskini. Wyniki badań hydrochemicznych i modelowe obrazują hydrogeochemiczną strefowość kompleksu wodonośnego drenowanego przez kamieniołom, warunkowaną budową geologiczną, warunkami krążenia oraz mikroklimatem jaskini. Wyróżniono anomalie przestrzenne związane ze zwiększonym zasilaniem ascenzyjnym z piętra wodonośnego kredy.
The paper presents the results of the research of the Badenian gypsum karst hydrogeochemical environment in the area of the Zoloushka cave in Ukraine. The investigations were carried out in June 2008 with the main aim of determining mechanism of cave lake waters chemistry. It has been found that the chemical mechanism of these waters is formed in a transitional hydrogeochemical environment. On the basis of the results of a hydrogeochemical numerical model, some of the features such as the distribution of elements, molar concentrations and main speciation as well as saturation indices (SI) for the chosen mineral phases were calculated. The chemical mechanism of the water was balanced with concentrations of O2 and CO2 present in the air of the cave. The results of hydrogeochemical investigations and modeling show a clear hydrochemical zonation within the described hydrogeological complex drained by the quarry. This is related to the geological structure, flow conditions and the cave microclimate. Spatial anomalies connected with the increased upward flow from the Cretaceous aquifer have been distinguished.

Opis:
Gips jest skałą o szerokim rozpowszechnieniu w skorupie ziemskiej i na jej powierzchni. Ze względu na określone wartości użytkowe gips jest pożądanym surowcem skalnym, wydobywanym najczęściej w kamieniołomach. Gips należy do skał krasowiejących i łatwo ulega rozpuszczaniu w wodzie. Dlatego gipsowe serie skalne, zalegające blisko powierzchni ziemi oraz masywy gipsowe są silnie skrasowiałe. Kamieniołomy gipsowe praktycznie zawsze odsłaniają skrasowiałe wnętrza masywów gipsowych, obfitujące w różnorodne formy krasowe i paleokrasowe, w tym jaskinie. Te ostatnie często są duże i reprezentują cenne lub nawet unikatowe utwory przyrodnicze, warte objęcia ochroną prawną. Utwory krasowe najczęściej decydują o wartości ogólnej kamieniołomów gipsowych, jako geostanowisk. W artykule, na przykładzie różnych kamieniołomów Podola i Bukowiny pokazane są ich walory wynikające z obecności utworów krasowych, przede wszystkim jaskiń.
Gypsum is a rock having a wide spread in the earth's crust and on its surface. Due to the specified usable values gypsum is a desired raw material, mostly mined in quarries. Gypsum belongs to karstic rocks and easily dissolves in water. Therefore, a series of gypsum rocks, lying close to the earth surface and gypsum massifs usually are strongly karstified. Gypsum quarries almost always expose the karstified interior of gypsum massifs, rich in various karst forms both karstic and paleokarstic, including caves. The latter are often large and represent a valuable or even unique natural formations, which should be taken under protection. Karst formations frequently determine the total value of gypsum quarries as geosites. In the article, the values of various gypsum quarries of Podilla and Bukovina resulting from karst formations, especially the caves, are shown, as examples.

Opis:
Water mites are predators on microcrustations (Copepoda, Cladocera, Ostracoda) and insect larvae (mostly Diptera). Their communities usually have great diversity with high species richness but relatively low abundance. This may have important implications for poorly investigated predator-prey interactions of water mites in natural habitats. A sublacustrine karst spring Torak and the mouth of its tributary river Čikola were examined seasonally from August 2016 to June 2017, with the aim of determining water mite distribution connected to prey availability. Triplicate samples were taken with an Ekman dredge on three distinct depth zones (littoral, sublittoral and profundal zone) at both study sites. Both, the karst spring and the tributary river, had typical lentic water mite communities with no rhithrobiont or crenobiont taxa present. Water mite species richness, abundance and alpha diversity were not governed by depth, but rather by prey availability. Greater copepod, ceratopogonid and chironomid abundances were found to positively correlate with higher abundances of water mites. The population of Limnesia connata, previously reported from lime-poor waters exclusively, was most probably supported by vast prey availability, thus unexpectedly surviving in this karst environment. L. connata, Neumania vernalis and Piona longipalpis were recorded for the first time in Croatia, while L. connata was recorded for the first time in the Dinaric karst.
Wodopójki są drapieżnikami odżywiającymi się mikroskorupiakami (Copepoda, Cladocera, Ostracoda) i larwami owadów (głównie Diptera). Ich zgrupowania zazwyczaj charakteryzują się dużym zróżnicowaniem gatunkowym, ale stosunkowo niską liczebnością. Może to mieć duże znaczenie dla wciąż słabo zbadanych relacji drapieżnik–ofiara w naturalnych siedliskach. Celem badań przeprowadzanych w okresie od sierpnia 2016 do czerwca 2017 roku w znajdującym się na dnie jeziora, krasowym źródle Torak i ujściu rzeki Čikola było zbadanie rozmieszczenia wodopójek w zależności od dostępności pokarmu. Próby pobierano chwytaczem Ekmana w trzech strefach głębokości (litoral, sublitoral i profundal) w obu badanych miejscach, za każdym razem wykonując trzy powtórzenia. Zarówno źródło krasowe, jak i dopływająca rzeka charakteryzowały się typowo lenitycznym zgrupowaniem wodopójek, bez obecności rhithrobiontów i krenobiontów. Bogactwo gatunkowe wodopójek, liczebność i wskaźniki różnorodności nie były związane z głębokością, lecz z dostępnością pożywienia. Stwierdzono, że większe liczebności widłonogów, ceratopogonidów i chironomidów korelują dodatnio z większą liczebnością wodopójek. Populacja Limnesia connata, poprzednio opisywana wyłącznie z wód ubogich w wapń, była najprawdopodobniej wspierana przez ogromną dostępność pokarmu, co niespodziewanie przełożyło się na jej przetrwanie w tym krasowym środowisku. L. connata, Neumania vernalis i Piona longipalpis zostały odnotowane w Chorwacji po raz pierwszy, natomiast L. connata została po raz pierwszy odnotowana na Krasie Dynarskim.

Opis:
Заброшенные карьеры могут представлять собой ценные в природоохранном отношении объекты. Статья посвящена Скитскому гипсовому карьеру, расположенному в каньоне Днестра (Западная Украина), который уже на протяжении более 50 лет «функционирует» в режиме натурализации. Охарактеризованы геологические, геоморфологические (карстово-спелеологические) и ландшафтно-экологические достоинства карьера, их охрана, а также пути возможного использования объекта.
The abandoned quarries can represents a valuable from the environment protection point of view objects. The article is devoted to Skitskiy gypsum quarry located in the canyon of the Dniester River (Western Ukraine), which for over 50 years functions in the mode of renaturalization. The geological, geomorphological (karstic-speleological) and landscape-ecological values of the quarry, their protection, as well as possible ways to use this object are characterized.

Opis:
Conducted by "Olkusz" Speleological Club exploratory works related to the Gieńkówka cave led only to its partial opening. There are indications stating that this cave has continuation beyond its currently available parts. In order to verify those assumptions resistivity imaging method has been used. During analysis of the resistivity models obtained from field measurements the synthetic model, simulating the intersection of the cave corridor, has been utilized. In order to assess the reliability of resistivity cross sections in terms of the presence of artifacts left by the inversion process Depth of Investigation (DOI) index has been applied. For preparing DOI maps two inversions on the same data set were carried out using different reference models. Then the results were compared to each other. High resistivity anomalies revealed on obtained models show strong correlation with actual caves known in this area. In addition, similar anomalies have been found in place of the predicted continuity in Gieńkówka cave, thus confirming the hypothesis made in this research. High DOI index values in the occurrence of caves pointing to the instability of the inversion process in those areas.

Opis:
This work performed by considering two complementary approaches for investigating the Karst system of Ras El Ma source: (1) The structural approach based on field studies, (2) The functional approach requiring inputs data (precipitations) as well as output data at the exit of the karstic system. The choice of the Ras El Ma source is justified by the fact that it constitutes the main outlet of the Liassic aquifer at the Southwest of Taza town. The structural approach highlighted that the impact of South Rifan and North Middle Atlas faults, oriented mainly NE-SW to ENE-WSW and NW-SE, tectonically linked to the Hercynian and late-Hercynian phases; these faults compartmentalized the karst into panels. The functioning of this karst system is based on the coupling of inputs and outputs, the analysis of interannual hydrograph, flood hydrographs, the recession curves and the analysis of hydrogeochemical results. Respectively, the obtained results are presented as follows: A close relationship between flow rates and precipitation, interannual hydrographs marked by a contrasting variation in flow rates and a periodicity that occurs between low water and high-water years. Concerning flood hydrographs, there are two types, a unit modal hydrographs type which generally occurs following time concentrated rainfall and a second multi modal hydrographs type which follows the repetitive rainfall in the basin. The study of recession curves reveals a clear complexity of the systems supplying the source. However, due to the low drying-off coefficients (7.66∙10-4), the aquifer seems to have a poorly developed drainage network in a flooded area. According to the Mangin method [1975], this karstic system is classified in the category of poor or complex karst systems taking into accounts two parameters (i) and (K), which characterize the functioning of the infiltration zone and the volume of flooded karst, respectively. The physicochemical parameters study highlighted the nature of drained rock by the sources. The correlation between conductivity and different chemical elements shows that bicarbonates and calcium are responsible for the mineralization of the waters of this source. It can be concluded that the low values of mineralization occur during the winter and spring floods. The spring regains its normal mineralization during the summer period.

Opis:
A characteristic features of the geological structure of the Krakow area are tectonic horsts and grabens. The Zakrzówek Horst is one of the seven horst structures within the Krakow area, located in the south-western part of the area. It is built of Upper Jurassic limestones, where numerous karst caves have been developed. The caves of the Zakrzówek Horst probably form a system of interconnected caves. This hypothesis has been tested in the western region of the Zakrzówek Horst using the electrical resistivity tomography (ERT) method. The investigations were conducted in the parallel profile configuration as well as with the data processing procedure based on the 2D and 3D inversion. The results of these studies are an attempt to locate additional voids as well as fractured zones in carbonate rock mass. The studies confirmed the hypothesis that the Jasna Cave is probably only a fragment of a vast cave system developed within the Zakrzówek Horst. As a result of the research carried out with the ERT method, the most prospective directions for future speleological research have been determined.
