Thuringia brooch
Opis:: In spring 2012 in the area of the village of Krzyżowice, approximately 15 km SW of Wrocław, an accidental discovery of a brooch was made. The brooch’s bow is cast in bronze, while the preserved fragments of the pin and spring were made of iron. Currently, the length of the artefact is 5 cm, but originally it was probably approximately 5.5 cm, because the base which is slightly curved upwards, was initially straight. All similar brooches come from the territory of the Thuringia tribe in the 5th/6th century AD, namely Thuringia and Bohemia. Such a dating places the brooch among the group of artefacts representing the youngest chronological horizon of the Przeworsk cultural area.

Opis:: Analysis of the Earth’s surface using three-dimensional models provides a wealth of new interpretation opportunities to geologists and geomorphologists. Linear elements, not visible on classical maps, become distinct features; it is also possible to interpret both small-scale glacial landforms and entire complexes of postglacial landscapes at the regional scale. Geomorphic features are frequently difficult to recognise in the field, either due to their scale or field obstacles. Three-dimensional visualization of the Earth’s surface and its examination at different angles and differently orientated source of light is extremely helpful in geological and geomorphological studies. This tool is, however, relatively seldom used due to either limited access to digital data bases or time-consuming procedures of individual construction of such bases from the existing cartographic data. For instance, analysis of small-scale glacial, fluvial or aeolian landforms in lowland areas requires cartographic data of resolution compatible with 1 : 10,000 scale. Nevertheless, less detailed digital elevation models, constructed at the scale of 1 : 50,000, are also extremely helpful, since they allow for regional interpretations of those morphostructures which are associated not only with neotectonics, but also with ice-flow directions, block disintegration of an ice-sheet, subglacial drainage, stages of fluvial erosion, or location of dune belts. A possibility of superposition of geological or geomorphological maps onto 3-D models is equally important, enhancing readability of the maps and providing clues to verification of the origin of landforms and proper cross-cutting relationships drawn on the map.

Otmuchów Depression
SW Poland
Opis:: This paper focuses on the problem of depositional environments and the development of glaciomarginal zone in the Otmuchów Depression, SW Poland, during the Odranian (Drenthe) glaciation. The research was conducted at the Wójcice site, which is situated on the southern border of a hill train, the so-called Otmuchów- Nysa Hills, rising on the northern side of the Nysa Kłodzka River valley. The sediments under study were deposited in the distal zone of glaciomarginal fans prograding into a bay of a large lake formed in the dammed valley of the Nysa Kłodzka River. Sedimentation was characterised by frequent oscillations of water level in the lake, which caused fan dissection and lateral migration of depositional subenvironments. These phenomena are recorded by abundant erosion surfaces and vertical succession of alternating lithofacies associations of the deposits, which are typical of different parts of the distal fans. Sedimentological analysis has also enabled palaeogeographical reconstruction of the glaciomarginal zone. It is found that the ice-sheet lobe advanced into the Nysa Kłodzka River valley from the NE.
Rozwój strefy glacimarginalnej na obszarze przedgórskiego odcinka doliny Nysy Kłodzkiej, zajmującego Obniżenie Otmuchowskie (Fig. 1), od dziesięcioleci stanowi przedmiot dyskusji. We wszystkich dotychczasowych rozważaniach geomorfologiczno- geologicznych i paleogeograficznych najwięcej uwagi poświęcano wyraźnie zaznaczonym w rzeźbie Wzgórzom Otmuchowsko- Nyskim (Figs. 1, 2). W pracy analizie poddano osady deponowane na południowym obrzeżeniu wzgórz. Badania prowadzono w stanowisku Wójcice, kilka kilometrów na zachód od Nysy. Szczegółowa analiza sedymentologiczna osadów umożliwi liwiła rekonstrukcję środowisk sedymentacji w rejonie SE obrzeżenia Wzgórz Otmuchowsko-Nyskich oraz wnioskowanie na temat paleogeografii strefy glacimarginalnej na obszarze Obniżenia Otmuchowskiego. W odsłonięciu Wójcice wyróżniono dwa kompleksy osadów. Kompleks 1, o miąższości ok. 10–12 m, zbudowany jest głównie z piasków drobnoziarnistych. W jego obrębie wyróżniono kilka tabularnych zespołów litofacji o nieznacznie odmiennym wykształceniu: Sh, (Sl); Sh (Sl, Sp); Sh, (Sl, Sm); Sh, Src; Src, SFw, (Sr) (Figs. 3, 4). W środkowej części kompleksu obserwowano również bardziej gruboziarnisty zespół SGm, Sm (Fig. 3). Cechą charakterystyczną kompleksu 1 jest obecność powierzchni erozyjnych oraz naprzemianległe występowanie zespołów litofacji o nieznacznie różnym poziomie energetycznym. Kompleks 2 obejmuje osady o miąższości ok. 4 m i charakteryzuje się grubszym uziarnieniem (Figs. 3, 5). W dolnej części przeważają średnio i gruboziarniste piaski lub piaski żwirowe (litofacje Sh, St, SGt). Wyżej obserwowano drobnoziarniste żwiry i żwiry piaszczyste (GSp, Gm) (Fig. 5a). W kompleksie 2 obserwowano ponadto niewielkie soczewy diamiktonu z materiałem skandynawskim (Fig. 5b). Pomiary azymutów upadu warstwowań przekątnych w obu kompleksach wykazały paleoprzepływy w kierunku NNW–NNE (Fig. 3). Analiza składu petrograficznego żwirów wykazała duży udział kwarcu, a także skał sudeckich oraz bardzo małą zawartooeć materiału północnego (Tab. 1). Osady kompleksu dolnego deponowane były w dystalnej strefie stożka progradującego do zbiornika wodnego. Depozycja odbywała się głównie z niskoenergetycznych zalewów warstwowych. Specyficzną cechą sedymentacji były częste wahania poziomu wody w zbiorniku powodujące rozcinanie stożków i oboczne przemieszczanie się stref depozycyjnych. Zapisem tego są nietypowe dla stożków zdominowanych zalewami warstwowymi powierzchnie erozyjne oraz powtarzające się w sukcesji pionowej zespoły litofacji osadów właoeciwych dla różnych części dystalnych stref stożków. Górny kompleks osadów związany był ze znacznie wyżej energetycznymi przepływami. Osady te były deponowane bliżej czoła lądolodu, co wraz z mułkami podścielającymi całą serię osadów piaszczystych wskazuje na transgresywny charakter całej sukcesji. Strefa marginalna lądolodu na obszarze Obniżenia Otmuchowskiego kształtowała się w inny sposób niż przyjmowano do tej pory (Fig. 6). W północnej jej części lądolód stacjonował w rejonie Wzgórz Otmuchowsko-Nyskich, natomiast w dolinę Nysy Kłodzkiej wsunął się z kierunku NE od strony doliny Odry w postaci niewielkiego lobu okalającego wschodnią część Wzgórz Otmuchowsko-Nyskich od południa. U czoła lądolodu w podpartej dolinie powstało rozległe zastoisko. U północnej krawędzi lobu osady były deponowane w postaci glacimarginalnych stożków progradujących do wąskiej zatoki zastoiska, która przypuszczalnie przez pewien okres była odizolowana od głównego zbiornika.

Opis:: This study deals with the spatial distribution and the PAAS-normalized patterns of rare earth elements (REE) studied by ICP-MS in the Kupferschiefer series of SW Poland. The most characteristic feature is a progressive enrichment in REE content (including Y and Sc) outward from the rocks with pyritic and Pb-Zn mineralisation, across the rocks with copper mineralisation, towards the oxidized (Rote Fäule) areas. The same trend can also be observed with respect to LREE, MREE and HREE. Whereas REE distribution diagrams for shales with pyrite and Pb-Zn mineralisation are almost flat, diagrams for shales with hematite and copper mineralisation are convex-upward and the strongest convexity is attributed to the transition from hematitic alteration to copper-rich rocks. REE distribution diagrams normalized to PAAS show strong MREE enrichment relative to LREE and HREE, which is typically the highest in the hematite zone, lower in shale with copper mineralisation, and the lowest in shales with Pb-Zn and pyrite mineralisation. The systematic increase in the concentration of REE towards the Rote Fäule, and the strong enrichment in MREE in the transition zone are indicative of variable intensity of leaching and formation of the REE enrichments (including MREE) by MREE>HREE>LREE fluids, as evidenced by the MREE-enriched signatures. Overprinting of secondary enrichments over the original REE pattern due to redistribution along the pathways of expanding fluids are postulated to account for the apparent differences in the distribution and concentration of REE (including the MREE-enriched trend) between the oxidized rocks, copper-bearing rocks, and reduced lithologies barren in copper.

Opis:: The oldest Cainozoic fluvial deposits in Lower Silesia date from the Oligocene. During the Middle and Late Miocene times, the fluvial system of this region was only slightly modified, especially in the foreland of the West and Middle Sudetes Mts. River lengths changed, following the migration of the North Sea shorelines. A rapid rebuilding of the fluvial system took place in the foreland of the East Sudetes Mts. either in the Late or Middle Miocene. Till that time, the main river valley of this region - the Nysa Kłodzka River, related to the Paczków and Kędzierzyn Grabens - used to flow towards the East, to a bay of the Paratethys sea. The new main river, pre-Odra, started to flow towards the North not before the Grodków Graben cut meridionally the Meta-Carpathian Swell. We are of the opinion that deposits of the Poznań Formation originated in an fluvial environment because no marine and/or limnic deposits have hitherto been discovered in the area of Lower Silesia above the uppermost of the Middle-Polish lignite seams (Henryk). The pre-Odra River drained the eastern part of Lower Silesia, and flowed towards the North, at least to the Poznań region. This main river captured such smaller rivers, as: the pre-Vistula, pre-Olza, pre-Ostravica, pre-Opava, pre-Nysa Kłodzka, and pre-Bystrzyca. Rivers draining the West Sudetes Mts. flowed first towards the North, to the region of the present-day Middle Odra River, and there turned to the West. It is conceivable that these rivers curved westwards just along the line of the present-day Wrocław - Magdeburg marginal stream valley ("Pradolina"). Since the Pliocene, the Sudetic rivers have started to transport coarser, sandy, and even gravelly material to a more distant foreland. Alluvial deposits of this phase occur exclusively on uplands. Coarse-grained sediments recognized in the bottom of deep erosional incisions were redeposited under subglacial conditions during the Mesopleistocene glaciations. The presented new interpretation of origin of the Poznań Formation basin and detailed recognition of Pliocene and Eopleistocene river system should initiate a new line of research into the Late Neogene and Eopleistocene sediments.

Opis:: Loess-soil sequences provide one of the most continuous and detailed records of the climate changes on land areas in the Quaternary. The Late Pleistocene loess section in Dankowice (Niemcza-Strzelin Hills) is one of the best recognized in SW Poland. For the investigation of the chemical composition of loess-soil sequence in Dankowice, 31 loess samples were tested. Ten main oxides were determined (SiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O, TiO2 and P2O5) using certified reference materials to obtain good credibility of the analysis. The chemical composition of loess from Dankowice is similar to the results presented in the world loess literature. The characteristic feature is extremely high concentration of the silica. The chemical composition of loess in Dankowice is differentiated within the vertical sequence and confirm previous division of litho-pedostratigraphic units. Therefore, the chemostratigraphic method can be successfully used as a one of lithostratigraphic methods. Decreasing values of the chemical weathering indices to the top of the section may indicate that the source areas of loess silt have provided material over time, less and less transformed by prolonged and intense chemical weathering processes.

Opis:: In the sandstones and conglomerates of the Idzików Conglomerate Member (Coniacian), exposed in the Idzików Quarry (SW Poland, Upper Nysa Kłodzka Graben), a moderately diverse assemblage of trace fossils has been recognized. The trace fossils include Arenicolites isp., Asterosoma isp., ?Bergaueria isp., Cylindrichnus isp., Conichnus conicus, Curvolithus simplex, Dactyloidites ottoi, Diplocraterion parallelum, ?Diplocraterion isp., Gyrochorte isp., Gyrophyllites aff. kwassizensis, Macaronichnus segregatis, Ophiomorpha nodosa, Ophiomorpha isp., ?Palaeophycus isp., ?Rhizocorallium isp., Rosselia isp., ?Scolicia isp., Teichichnus isp. and Thalassinoides isp. Escape traces (fugichnia) and some unidentified trace fossils also were found. The following ichnoassociations are distinguished: (IA1) Ophiomorpha-Cylindrichnus, (IA2) Asterosoma-Conichnus and (IA3) Ophiomorpha- Arenicolites. IA1 probably represents a mixture of the impoverished proximal Cruziana ichnofacies and the distal Skolithos ichnofacies, which points to the lower, weakly storm-affected shoreface. IA2 is interpreted as the archetypal Skolithos ichnofacies (opportunistic colonization of tempestite beds) with some elements of the Cruziana ichnofacies (bioturbated, fair-weather background deposits) in the middle, moderately storm-affected shoreface. IA3 is assigned to the archetypal Skolithos ichnofacies, which indicates the upper shoreface-foreshore settings. The trace-fossil evidence implies that the Upper Cretaceous succession was deposited in a shallow, open basin with good oxygenation of the sea floor and normal salinity, under low- to moderately high-energy hydrodynamic conditions. On the basis of ichnological and sedimentological analyses, the deposits studied originated in a system of fan-delta and shallow-shelf settings with common transitional-proximal tempestites. They were deposited in the eastern part of the Upper Nysa Kłodzka Graben during the Coniacian regression.

Opis:: In the following paper, the analyses of morphology of settlements were conducted using graph methods. The intention of the author was to create a quantifiable and simple measure, which, in a quantitative way, would express the degree of development of a graph (the spatial pattern of settlement). When analysing examples of graphs assigned to a set of small towns and large villages, it was noticed that the graph development index should depend on: a relative number of edges in relation to the number of nodes (β index), the number of cycles (urban blocks), which evidences the complexity of the spatial pattern of settlement, and the average rank of nodes of a graph, which expresses the degree of complexity of a street network.

Opis:: This work aims at estimation of the amount of metamorphic fluids which led to the present-day variability of isotopic compositions, ?D and ?18O, in serpentinites from the Gogołów–Jordanów Massif. This goal was achieved by means of a numerical model reproducing selected features of geological environment and a computer application supporting this model. The Gogołów–Jordanów Massif consists of peridotites transformed to a different degree into serpentinites and subject to brittle deformation that produced a complex fracture system. The potential tectonic control on the pattern of the fluid migration paths was investigated using palaeostress analysis based on slickenside measurements. Isotopic analyses were carried out for hydrogen and oxygen from serpentine, oxygen from magnetite, and hydrogen and oxygen from carbonates. The variability of ?D and ?18O in the serpentinites along the modelled migration paths demonstrates that serpentinization of peridotites was caused by fluids derived from at least three sources revealing different isotopic characteristics. Fluids produced during the magmatic-hydrothermal stage played a major role in serpetinization, since they represent approximately 95% of all fluids interacting with the rock. In contrast, oceanic water represents only 1% of fluids involved in serpenti- nization. The calculated mean amount of fluid required for serpentinization of 1 m3 of peridotite is equal to 98 × 104 kg.

Opis:: The development of basal Zechstein (Wuchiapingian) strata inSW Polandindicates the existence of a diversified relief inherited after the flooding of the pre-existing depression by the transgressing Zechstein sea. The deeper parts of the basin were the place of development of thin basinal Zechstein Limestone showing sedimentary condensation manifested by bored and encrusted grains and thick evaporites (mostly halite), and in shallow parts Zechstein Limestone reefs followed by thinner evaporite sequences (dominated by anhydrite) occur. The analysis of 3D seismic sections showed that instead of three conventionally recognized evaporite units of stratigraphic potential in the PZ1 cycle, five units occur (from the base to the top: Lower Anhydrite, Lower Oldest Halite, Middle Anhydrite, Upper Oldest Halite, Upper Anhydrite). In a particular place their number may vary from two (Lower Anhydrite at the base of the PZ1 cycle and Upper Anhydrite at the top of the PZ1 cycle) to five. There are two complexes of Lower Anhydrite occurring throughout the platform and basinal zones showing deepening-upward (transgressive) trend. The halite sedimentation in the deepest parts of salt basins began shortly after the deposition of the upper Lower Anhydrite complex while in the sulphate platform areas the sulphate deposition lasted still for a long time. The Lower Oldest Halite deposits occur in the depressions. Between the halite basins, anhydrite platforms occur, and the thickness of anhydrite platform deposits is smaller than it is observed in salt basins. The Upper Oldest Halite in turn is recorded above the anhydrite platform. The two halite units represent different phases of development of halite basins. The Lower Oldest Halite basins are related to the pre-Zechstein depressions, although in some cases their syndepositional subsidence was controlled by reactivation, during the deposition of basal Zechstein strata, of former faults. In turn, the Upper Oldest Halite basins used the accommodation space created due to anhydritization of the Lower Anhydrite deposits composed originally of selenitic gypsum. The 3D seismics evidences that the PZ1 evaporites inSW Polandhave been deposited in far more complex and dynamic system than it was assumed before.

Opis:: The paper presents the results of precipitation influence on the discharge regime changes of 6 springs located in south-western Poland and draining a variety of rocks differing in lithology and age. Calculations for the very wet (2010) and the extremely dry years (2015) have shown that the low spring discharges experienced the greatest variations, with the coefficient ofvariation falling between 3-141%. The coefficient of variation for the maximum and average discharges generally does not exceed 90%. The obtained values of the regression coefficient from 0.0016 to 0.1 d-1 and the coefficient of variation (0-33%) indicate a relatively low variability of groundwater resources and the low transmissivity and high storage capacity of the weathering cover. The spring discharge analysis indicates also the drainage of groundwater bodies of various capacity. The maximum values of the storage capacity are several hundred thousand cubic meters, whereas in the lowest spring resources it does not exceed several thousand cubic meters. Three springs have shown a low variability of the storage capacity (Cv = 4-32%), two have indicated a moderate variability (66 and 70%) and one has shown a large variability (135%). The large storage capacity and high hydraulic resistance of the weathering cover does not guarantee the spring recharge during longer periods (summer-autumn) without rain.

Opis:: Intensywne badania geologiczne, prowadzone od połowy ub. wieku na omawianym obszarze przedsudeckim, umożliwiły rozpoznanie wystąpień późnopermskich (cechsztyn) soli kamiennych i potasowo-magnezowych. Zaowocowało to udokumentowaniem 2 złóż soli kamiennej: Sieroszowice i Bądzów o zasobach bilansowych wynoszących 4,09 mld Mg, w tym 0,49 mld Mg zasobów przemysłowych. Zasoby szacunkowe (prognostyczne) soli kamiennej, jako kopaliny towarzyszącej w 6 złożach rud miedzi, oceniono na ok. 45,19 mld Mg. Celem wskazania na obszarze przedsudeckim występowania obszarów perspektywicznych wystąpień cechsztyńskiej soli kamiennej i soli potasowo-magnezowych oraz oszacowania ich zasobów przewidywanych (prognostycznych + perspektywicznych) opracowano łącznie 34 arkuszy map w skali 1:200 000. Przygotowano 28 map dla 4 pokładów soli kamiennej, odpowiadających 4 cyklotemom cechsztynu (od PZ1 do PZ4) i 6 map dla 2 serii potasonośnych, związanych z cyklotemami PZ2 i PZ3. Przewidywane zasoby soli kamiennej, oszacowane dla 42 obszarów perspektywicznych, wynoszą ponad 1 bln Mg, a ich powierzchnia to ponad 18,5 tys. km2. Ostateczna wielkość zasobów przewidywanych, pomniejszona o zasoby wspomnianych 6 złóż miedzi, wynosi ponad 995,7 mld Mg. Doliczając udokumentowane zasoby 2 złóż soli kamiennej, łączne zasoby soli kamiennej na obszarze przedsudeckim do głębokości 2 km można szacować na blisko 1000 mld Mg. Przewidywane zasoby soli potasowo-magnezowych, oszacowane dla 9 obszarów perspektywicznych, wynoszą blisko 3,3 mld Mg, a ich powierzchnia to ponad 456 km2. Wiele wskazanych obszarów perspektywicznych wystąpień soli kamiennej ze względu na dużą miąższość pokładu soli może być rozważane nie tylko jako miejsce wydobycia soli (kopalnia podziemna i ługownicza), ale także jako miejsca budowy kawernowych magazynów węglowodorów (gazu ziemnego i ropy) czy wodoru, bądź składowisk odpadów. Niektóre spośród wskazanych wystąpień soli potasowych i potasowo-magnezowych mogą być również zagospodarowane górniczo, jednak dopiero po ich dokładnym geologicznym rozpoznaniu i określeniu zasobów.
Intensive geological prospection in the Fore-Sudetic area in the second half of the 20th century enabled to recognize occurrences of late Permian (Zechstein) rock and potash salts and to contour two rock salt deposits: Sieroszowice and Bądzów (with the registered anticipated economic resources of 4.09 billion Mg and economic resources of 0.49 billion Mg), as well as to estimate the prognostic rock salt resources in six copper deposits at ca. 45.19 billion Mg. To contour the prospective areas of Zechstein rock and potash salts occurrences in the Fore-Sudetic area and to estimate their predicted (prognostic and prospective) resources, 34 map sheets at scale of 1:200,000 have been compiled. Twenty-eight map sheets have been constructed for four rock salt seams, representing the four Zechstein cyclothems (PZ1 to PZ4), and six map sheets for two potash-bearing series of the PZ2 and PZ3 cyclothems. The predicted rock salt resources, estimated for 42 prospective areas, are more than 1x1012 Mg, covering the total acrea of over 18.5 thousands km2. The final amount of these resources, reduced by the amount of resources of the above-mentioned six copper deposits, is over 995.7 billion Mg. Including the documented resources of two salt deposits, the total amount of Zechstein rock salt, in the study area down to a depth of 2 km is estimated at ca. 1000 billion Mg. The predicted resources of Zechstein potash salts in nine prospective areas were estimated at ca. 3.3 billion Mg with the total area of over 456 km2. Many prospective areas with significant thicknesses of rock salt seams could be managed both for salt production (underground and leaching mines) and as cavern storages (for hydrocarbons or hydrogen) and waste disposals. Only some of the indicated areas of potash salts could be considered for future mining, however, after their detailed geological surveying and resource calculation.

Opis:: Basic statutory task of the Polish Geological Institute-National Research Institute within the framework of the State Geological Survey is conducting detailed geological mapping ofPoland. One of the leading themes of the III Polish Geological Congress is the "Geological mapping - history and contemporary challenges”. The article presents an analysis of the current state ofdetailed geological mapping in the Sudetes and adjacent areas, as well as the reasons for the need to start a new, second edition of the Detailed Geological Map of the Sudetes (SMGS) at the scale of 1 : 25,000. These reasons can be briefly defined as follows: long-lasting duration of the SMGS development (nearly half a century), lack of uniformity, and outdatedness of this edition. The first edition covered 139 map sheets at the scale of1 : 25,000, with a total area over 10,100 km2. The newly presented comprehensive project assumes very fast workflow, just 10 years of work before the implementation of the second edition of the 1 : 25,000 SMGS. The new edition is going to be more modern and based on the new classification of rocks, providing more information about their origins, geotectonic settings, as well as the processes and geological phenomena, which are not included in the first edition of the 1 : 25,000 SMGS.

Opis:: The sequence of Weichselian sediments and processes in SW Poland is almost identical to that of central Poland. Generally, three fluvial units occur, comprising silts and sands coarsening upwards to silts, sands and gravels, with aeolian deposits on top. This suggests very uniform processes throughout the palaeogeographic zone. To the south of this zone, there was extensive loess deposition and glacial deposition to the north. Climatic conditions during the Middle and Upper Weichselian Pleniglacial in SW Poland were similar to those in central Poland and northwestern Europe, though the period of 47-43 kyrs BP was slightly milder in SW Poland (shrub tundra, forest-tundra). Climatic conditions during the periods 38-27 kyrs BP and 23-18 kyrs BP were very uniform throughout central Europe, including SW Poland, though there may have been a strong north-south climatic gradient during the former period, as data from the loessic zone indicate at least patches of boreal forest or forest-tundra conditions in SW Poland at that time. It is also possible that there was a Middle Weichselian Pleniglacial interstadial with a lower age boundary at 25,900 ą 700 years BP, characterised by Pinus-Picea forest with no heliophytes. This interstadial represents the last mild period before the advance of the late Weichselian ice sheet into SW Poland. The Weichselian fluvial deposition of SW and central Poland may have been punctuated by at least three major erosional phases, characterised by similar incision depths during the cold stages. Erosion took place, with certainty, at around 75-60 kyrs BP (Lower Pleniglacial) and 27 kyrs BP, very probably at around 23/22 kyrs and possibly at around 40 kyrs BP, and valley aggradation occurred during the milder stages. The Upper Pleniglacial was characterised by valley aggradation, associated with southward ice sheet advance and restricted fluvial outflow. However, the frequent Middle Pleniglacial Weichselian climatic oscillations did not initiate sedimentation and erosion, they controlled only river discharge and type of fluvial sedimentation and aeolian activity. The occurrence of the erosional and aggradational phases were controlled by the changes in ice volume in Scandinavia, ice sheet build-up and retreat, respectively.

Opis:: The paper presents the characteristics of prospective zones identified for the first time within the lower Palaeozoic shale formations occurring in the Baltic-Podlasie-Lublin Basin and within the Carboniferous shale, sandstone, and mixed shale-sandstone complexes (the so-called hybrid complexes) in the basin of south-western Poland. The lateral and vertical ranges of these zones are determined based on specific criteria using the results of various research methods and analyses, i.e.: stratigraphic, sedimentological, mineralogical, petrological and geochemical of organic matter, petrographic and petrophysical, including interpretation of well logs. Archived geological materials and those coming from the boreholes drilled recently in the concession areas were also used. Four prospective zones have been distinguished in the lower Palaeozoic of the so-called shale belt: SP1, SP2, SP3 and SP4. The most prospective area for the occurrence of unconventional hydrocarbon deposits in shale formations is the Baltic region – the Łeba Elevation, where there are all four perspective zones, only partially covering the range of potentially prospective formations. In each of these zones, both liquid and gas hydrocarbons can be expected in this area. Due to the low percentage of organic matter, the lowest hydrocarbon generation potential is attributed to the Lublin region. However, the low values of this parameter are compensated by other parameters, i.e. the considerable thickness and lateral extent of zone SP4 corresponding partly to the Pelplin Formation. In the Carboniferous rocks of south-western Poland, seven prospective zones have been distinguished in four borehole sections. Four of them are “tight” zones in compact sandstones, while the other three zones represent a hybrid type in complexes with mixed lithology. No prospective zones have been defined in complexes with homogeneous shale lithologies. Determination of lateral extents of the identified zones has not been possible due to the scarcity of data on the geological structure and stratigraphy of the Carboniferous succession in the study area

Opis:: Reconstruction of burial and thermal history was modelled for the Mesozoic strata in the basement of the Polish and Ukrainian parts of the Carpathian Foredeep and in the marginal part of the Outer Carpathians. The 1-D modelling was carried out in profiles of the wells located in the area between Tarnogród and Stryi towns. In the Polish part, the modelling were performed in the profiles of the Księżpol 15, Lubliniec 9, Markowice 2 and Opaka 1 wells, and in the Ukrainian part in the profiles of the Chornokuntsi 1, Korolyn 6, Mosty 2, Podiltsi 1 and Voloshcha 1 wells. The geochemical characteristics of the Mesozoic stratigraphical horizons revealed that the best features of source rocks were present in the Middle Jurassic strata in the Polish part of the study area and in the Middle and Upper Jurassic strata in the Ukrainian part. Within these strata, the horizons of source rocks were distinguished and their quantitative evaluations were characterized. For these horizons, reconstruction of processes for hydrocarbon generation and expulsion were performed. The source rocks in the Polish part reached maturity only in the initial phase of “oil window”. However, the maturity achieved towards the end of the Upper Jurassic was insufficient to exceed the 10% threshold of the transformation degree for hydrocarbon generation. Therefore, the amount of generated hydrocarbons was minimal. Slightly higher maturity of organic matter in the Ukrainian part resulted in exceeding the thresholds of kerogen transformation and the initiation of hydrocarbon generation and expulsion processes. The process began after the deposition of thicker Miocene formations and developed even up to the main phase of the "oil window". The amount of the generated hydrocarbons reached ca. 150 mg/g TOC with an insignificant volume of expulsion.

Opis:: There is evidence, hitherto often denied, for the ice marginal features, including the end moraine hills along the Silesian Rampart, SW Poland. These end moraines are attributed to the regional advance of the Wartanian ice sheet into its maximum position, which is also marked by subglacial till bed. The end moraine hills are located on the northern slopes of the Silesian Rampart and they are very rare, partly due to subsequent erosion, but mainly due to conditions not favourable for a remarkable proglacial accumulation. The Wartanian end moraines of southwestern Poland possess several features that suggest that they are end moraines with dominant waterlain, stratified sediments. They are interpreted as alluvial fans, where the ice margin is represented by a 'scarp'. They have semi-conical form, often plano-convex geometry and an average distal slope of 2-25°. These fans are equivalent to sheetflow-dominated or 'humid' alluvial fans in non-glacial environments. Sedimentary sequences of the end moraines consist mainly of coarse-grained material, with boulders up to 1.8 m in diameter, with typical sediments of 'proximal fan' with a highly pulsatory water discharge. The formation of the end moraine followed the formation of a proglacial lake and strong erosion after its drainage. The end moraine was formed during oscillation of the ice margin that resulted in local glaciotectonic deformation of the end moraine fan sediments (push) and a set of parallel hills, with successive younger alluvial fans (retreat).

Opis:: A block development operation at the "Rudna" copper mine (KGHM Polska Miedź S.A.) encountered a "compressed gas trap" that caused the ejection of fragmented rock material into a drift. Faced with a new threat of gas ejection the mine needed to find methods to identify potential gas concentration zones prior to any further exploration work. Surface seismic surveying was chosen as a widely-accepted standard method of investigating rockmass structure and tectonics and pinpointing natural gas deposits. An area of one square kilometre was selected directly above the ejection site, a 3D seismic survey, known as Duża Wólka 3D, was performed and a survey well S-421A was drilled. The objective was to investigate the overall rock structure, especially the structure of Zechstein and top Rotliegendes formations, as well as to attempt identifying anomalous zones, which could be linked with the gas saturation of Ca1 dolomites, on the 3D seismic image at the P1 level (Zechstein/ Rotliegendes boundary). An interpretation of multi-scenario seismic modelling of the recorded data helped to: – recognize the structure and tectonics of the area, including minor faults cutting through the top-level Rotliegendes formations and floor-level Zechstein formations. Such faults could constitute migration channels for Carboniferous-period gases, – locate zones with nearly zero-reflection amplitude at the surface of the top-level Rotliegendes (P1 seismic boundary), which would suggest a reduction of elastic parameters of the Ca1 dolomite. This reduction could be linked to an increased porosity and fracturing of the dolomite and its saturation with gas (a reduction of the seismic wavelet propagation velocity). Credibility of this interpretation is already partly corroborated by data from wells drilled in the Zechstein limestone by the mine. The paper presents the first in the world attempt to use the surface seismic survey for location of zones with small gas concentration in porous rocks at the Zechstein/Rotliegendes boundary. Such zones should not be identified with gas pools that occur in the Zechstein Limestone (Ca1) in the area of the Fore-Sudetic Monocline.

Opis:: Themost significant copper reserves in Poland are confined to sediment-hosted stratiform Kupferschiefer-type deposits that occur at the Zechstein/Rotliegend transition. Gradual depletion of shallow reserves in the Fore-Sudetic Monocline results in exploration of deeper beds, and the long-term challenges require new solutions for mining industry of the future and industrial market within the EU, to enable the reindustrialization of Europe. Latest studies of numerous drillhole cores strongly indicate that the Kupferschiefer series in SW Poland (outside the Lubin–Sieroszowice Copper District) contains a very large volume of prognostic, prospective and hypothetical resources. Thirty Cu-Ag prospects have been delineated (including six areas with prognostic resources, six with prospective resources, and 18 areas with hypothetical resources). Among the prospective areas, particular attention is paid to the areas with prognostic resources (Bia³o³êka, Grochowice, Krêpa, Kulów, Luboszyce), adjacent to the existing mines of the Lubin–Sieroszowice copper district. The areas of Nowiny, Mirków, Raciborowice and ¯arków are also interesting due to accessible depths, and the Bogdaj, Henrykowice, Janowo and Sulmierzyce areas due to considerable resources and reasonable depth. Extremely interesting is the possibility of extension of the Bytom Odrzañski deposit towards the Jany, Mozów and Wilcze prospective areas. Studies of archival drillhole cores taken outside the documented Cu-Ag Lubin–Sieroszowice deposit revealed Rote-Fäule-related Au-Pt-Pd mineralization in many localities of SW Poland. Fifteen Au prospective areas, accompanied by Pt-Pd mineralization, have been delineated. However, due to relatively low thickness and content, Au-Pt-Pd mineralization can be considered only as associated with the overlying Cu-Ag ores. It can be estimated that approximately 166 million Mg Cu and 269 thousand Mg Ag concentrated as predicted resources in prospects of SW Poland for future mining, which will be possible, when geological and technological barriers (depth, temperature, oil and gas) will meet economic trends in the world market.

Opis:: Analiza obecnego występowania i zróżnicowania miąższości utworów ewaporatowych (siarczanowych i chlorkowych) górnego permu (cechsztyn) na obszarze centralnej części monokliny przedsudeckiej, bazująca na danych z 635 archiwalnych otworów wiertniczych, umożliwiła przedstawienie obrazu przypuszczalnej paleogeografii basenów siarczanowych i chlorkowych w przypadku niektórych ewaporatowych wydzieleń litostratygraficznych kolejnych czterech cyklotemów. Utwory siarczanowe i chlorkowe cyklotemów PZ1 i PZ3 oraz siarczany cyklotemu PZ2 (anhydryt podstawowy [A2]) powstały w zbiornikach o wyraźnie zróżnicowanej batymetrii, ze strefami płytszymi (bariera i płycizny) i głębszymi (baseny). Akumulacja tych osadów następowała według schematu występującego w basenie typu „wypełnieniowego”, w którym na etapie depozycji soli chlorki wypełniają głównie obniżenia dna wcześniejszego zróżnicowanego batymetrycznie zbiornika siarczanowego, zaakcentowane różnym tempem osadzania siarczanów (szybszym na płycinach i wolniejszym w basenach). Lokalne występowanie pozostałych ewaporatów cyklotemów PZ2 i PZ4 nie pozwala otworzyć paleogeografii ich zbiorników depozycji. Omówiono też wykształcenie wydzieleń ewaporatowych, wykorzystując dane z terenów sąsiadujących z obszarem badań w sytuacji braku miejscowego materiału rdzeniowego.Tektonika dysjunktywna (sieci uskoków i dwa rowy tektoniczne) w różnym stopniu przemodelowała pierwotne rozmieszczenie ewaporatów i spowodowała ich lokalny wzrost miąższości w strefach przyuskokowych.
Analysis of recent extension and thickness of Upper Permian (Zechstein) evaporites (sulphates and chlorides) in the area of central Fore-Sudetic Monocline, based on data from 635 archive boreholes, enabled to reconstruct the possible palaeographic images of both sulphate and chloride basins, represented some evaporitic lithostratigraphic units of four Zechstein cyclothemes. Sulphates and chlorides of PZ1 and PZ3 cyclothemes as well as sulphates of PZ2 cyclotheme (Basal Anhydrite [A2] unit) have deposited in the basins with distinctly varied bathymetry, where existed the shallow (barrier and shoals) and the deeper (basins) parts. Their accumulation realized the depositional scheme of the „infill” type of evaporitic basin, after which dominant infill by chlorides took place in the deeps of former sulphate basin with differentiated bathymetry accentuated by other accumulate rate of sulphates (a higher on bottom shoals and slower in the deeps). Local occurrence of other evaporate units of PZ2 and PZ4 cyclothemes eliminated creation of similar palaeogeographic images for their depositional basins. Commented evaporite units were characterized by data representative for their age equivalents drilled in the nearest areas because of extremely rare core data form the study area. Disjunctive tectonics (fault systems and two tectonic grabens) modified in a different rate the primary extent of studied evaporites as well as it was responsible for their local thickness increase in the near-fault zones.

Opis:: Fifteen samples of basaltoid rocks have been analysed from the Lower Silesia, SW Poland, some of them from localities close to the Sudetic Marginal Fault. K-Ar datings have been made on whole rock samples, using the methodology applied by the Institute of Nuclear Research, Hungarian Academy of Sciences, Debrecen, Hungary. Most of the samples give ages ranging between 21- 38 Ma, whereas that derived from a borehole in the Mokrzeszów Graben has been dated to 44 Ma. Another borehole sample (Jeżów Sudecki B-5), close to the Intrasudetic Fault, is of 59 Ma age. On the other hand, the supposedly "Quaternary" basaltoids from Dębowiec area fall into the interval of 29–30 Ma. The southeasternmost occurrences of the Lower Silesian basaltoids at Nowa Cerekiew display two generations of effusive activity: the older lava flows (26 Ma) are cut by plugs dated to 22 Ma. The Oligocene–Lower Miocene (26-33 Ma, 20'24 Ma) rocks represent alkali basalts and basanites. The alkali basalts consist of phenocrysts of olivine (chrysolite), altered to a different degree, and clinopyroxene (salite). In the matrix, clinopyroxene (Ti-salite), olivine (hyalosiderite), plagioclases (labradorite–andesine), and opaque minerals (titanomagnetite, ilmenite) occur. The basanites contain phenocrysts of altered olivine (chrysolite) and clinopyroxene (salite). Their matrix consists of clinopyroxene (Ti-salites), olivine (hyalosiderite), nepheline, plagioclases (bytownite–andesine), and opaque minerals. On the TAS diagram, samples of the studied basaltoids plot mainly in the fields of basalts and basanites/tephrites. The bimodality of some samples falling into two fields of basalts and basanites/nephelinites on the TiO2/Zr-Nb/y diagram results from their distinct geochemical signature.

Opis:: The study deals with clay-silt shales occurring in the lower Palaeozoic basin at the western slope of the East European Craton, and sandstones known from the Carboniferous Basin of SW Poland (basement of theFore-SudeticHomocline).The clay groundmass of the shales consistslargely of illite, and the silt fraction is made up of quartz with a variable admixture of feldspars. Quartz and carbonate cements are common, while pyrite, kaolinite and phosphate cements are rare. The clay groundmass reveals microporosity in the form of microchannels paralleling illite plates, and visible with in mica packets. Carboniferous sandstones are represented mostly by sublithic or subarkosic wackes and rarely by lithic, sublithic or subarkosic arenites. The pore space between sand grains is completely filled by clayey matrix. Both porosity and permeability are very low in the sandstones.

Opis:: This paper presents the results of analysis of landslides distribution in the Sudetes (SW Poland). Our study was based on the analysis of the LiDAR-data digital elevation model and integrated with investigations of different factors for landslide development. The results of the study showed relationships between the spatial distribution of landslides and geology of their basement. For the areas built by Permo-Mesozoic and late Variscan sedimentary and volcanogenic rocks, the tectonic and lithological factors are predominant for landslide occurrences. The largest landslides have a tectonic affinity and represent a frontal type of geometry. The relationships between geological conditions and mass movements were also confirmed by the constructed landslide susceptibility map of the Sudetes.

Opis:: The paper reviews an application of non-destructive electromagnetic imaging of shallow bedrock and landslide colluvium horizons performed with ground-penetrating radar (GPR) technique on mass movement-affected mountain slope. We used a non-shielded 52 MHz GPR equipment to study an area of a shallow translational landslide, which developed on steeply inclined gneissic bedrock on Mt. Sredniak slopes (1210 m a.s.l.) in the Śnieżnik Massif. This landslide originated at the boundary zone between intact bedrock comprising Proterozoic gneisses and uppermost slope cover, as a result of continuous rainfall during July of 2011. Furthermore, to better understand and examine a landslide area on Mt. Sredniak slopes we also applied structural geological and geomorphological methods. The GPR analyses resulted in high-resolution imaging of internal slope structure and gravitational deposit architecture in the range of 0.5-5 m below surface level. Electromagnetic sounding performed directly above the landslide source area elucidated a set of bedrock discontinuities with a possible direct impact on water aggregation and migration during the rainfall episodes. Furthermore, a GPR profile performed in a landslide toe area, showed subsurface reflection horizons to be correlated with a colluvium/bedrock transitional zone and internal heterogeneous architecture of colluvial deposits. Ground-penetrating radar proved to be both powerful and an easy-maintained 'on-site' method for steep mountain slope analysis, with a potential for high-resolution imaging of shallow-seated gravitational slope deformations.

Opis:: South-west Poland (Silesia) is the region of dramatic history which has left significant heritage, comprising, e.g., numerous historical castles. In this paper, we describe selected castles in Lower Silesia, with special attention given to the usage of exotic (imported) decorative stone materials traded across Europe in various historical periods. Out of the total number of c. 100 historical castles and palaces in SW Poland, only three of them, i.e. Czocha, Ksi¹¿ and Moszna, have preserved significant amount of the original stone decoration. In Czocha Castel, apart from local stones, we have identified, e.g.: red and white, and grey limestones (from Belgium, Germany or Italy). In Ksi¹¿ Castle, the interiors have a great variety of exotic stone materials: travertine, marbles and limestones, e.g. Rosso di Francia, and many others, mostly from France and Italy. In Moszna Castle, representative rooms are adorned with “marbles”: Rosso di Verona, Giallo di Verona, Giallo Siena, Rosso di Francia, and serpentinites and ophicalcites (from Austria and Italy). Most of the exotic stones in the three castles studied were imported at the turn of the 19th–20th centuries and in the early 20th century, when the castles were largely reconstructed and redecorated.
