Opis:
The history of modern geological mapping in Poland began with the Carta Geologica totius Poloniae, Moldaviae, Transylvaniae, Hungariae et Valachiae by S. Staszic, often called the “father of Polish geology”. Before Staszic, a general map of Poland had been published by J.-E. Guettard (1764a); ones of the Sudety Mts. by J. Jirasek (1791), L. von Buch (1797), and Raumer (1813); and that of the Tatra Mts. by Hacquet (1796). In times of the partition of Poland (1772 to 1918), areas annexed by Prussia were covered by systematic geological surveys. These cartographic projects resulted in the compilation of two geological atlases comprising maps of the standard sheet type, in the period from 1826 to 1836. These atlases were compiled by teams of outstanding geologists, under the leadership of L. von Buch and F. Hoffmann. Another outstanding contribution to the geology of Poland was made by G.G. Pusch, the author of the excellent Geognostische Beschreibung von Polen (1833–1836), subsequently supplemented by Geognostyscher Atlas von Polen. One of the greatest achievements of L. Zejszner was the geological map of the Tatra Mts., Carte de la chaine du Tatra, published anonymously in Berlin in 1844, and a series of geological maps prepared as drafts of Geognostic maps of the Eastern District of the Polish Kingdom. Special attention should be also paid to two extensive studies which covered areas of Upper and Lower Silesia. The first of these, Geognostische Karte von Oberschlesien und den Angrenzenden Gebieten, was completed by a team led by F. Roemer, and published in 1870. The second, Geologische Karte von dem Niederschlesischen Gebirge und den angrezenden gegenden, was compiled by a team led by R. von Carnall, and published in the same year. Out of all the studies carried out by Austrian geologists, it is necessary to mention those of E. Tietze, as they produced excellent geological maps of the Carpathians and vicinities of Kraków and Lviv. It is also worth mentioning the contributions made by the Physiographic Commission, active from 1866 until the beginning of the First World War. Its members decided to prepare the Geological Atlas of Galicia. The final product of works of this commission was a set of 25 booklets, with over a hundred geological maps at a scale 1:75000, issued in the years 1885–1912. From 1881, the commission was also publishing its famous Physiographic Diaries, which include papers on the geology of areas annexed by Russia, written by famous Polish geologists such as J. Siemiradzki, A. Michalski, and E. Habdank-Dunikowski, illustrated with relevant geological maps prepared by them.

Opis:
Design and construction of hydrogeological information systems is now a necessity. For proper functionality of these systems, it is necessary to create them in accordance with widely accepted international standards regarding geospatial information. Geomatics research tools allow for creation of basic models of hydrogeological data, consistent with these standards. The models can be based upon classification of types and subtypes of hydrogeological features, as well as upon basic and derived classes of hydrogeological objects. The basis for this classification can be differentiation between features and objects, as well as between fuzzy features (objects) and fiat features (objects), or the analysis of their spatial dimensionality.

Opis:
Systematic geological mapping of the Slovak Republic territory over the last forty years, when many regional geological maps at 1:50 000 scale were issued, culminated in 2008 and 2009 in a new synthesis of the geological structure of the Western Carpathians on the Slovak territory in the form of a general geological map at 1:200 000 scale. An integral part of this activity was the solving of interregional correlation problems, a settled of tectonic classification of the Western Carpathians as well as a specification of the lithostratigraphical content of the tectonic units. The results of this synthesis are described in this contribution - a brief review of the principal geological units of the Western Carpathians that are depicted in the tectonic interpretation and in the geological sections. The Western Carpathians are geologically divided into the Outer (Flysch Belt) and Inner (Inner Carpathian Block). These two zones are products of the youngest, mainly Neogene Neo-Alpine tectonic activity. Separating the two zones is a tectonic structure - the Klippen Belt -which contains elements from both. The Inner Carpathian Block possesses a Palaeoalpine tectonic pattern composed of crustal tectonic units and superficial nappes. The crustal units are composed of the crystalline basement and its Upper Paleozoic and Mesozoic cover. The basement consists of fragments of Hercynian tectonic units from the Paleozoic phase of crustal evolution. The superficial nappes comprise mostly upper Paleozoic and Mesozoic sequences. Cenozoic deposits and volcanic rocks are deposited on the Palaeoalpine nappe structure.

Opis:
The hydrogen and oxygen isotopes of water and the carbon isotope composition of dissolved inorganic carbon (DIC) from different aquifers at an industrial site, highly contaminated by organic pollutants representing residues of the former gas production, have been used as natural tracers to characterize the hydrologic system. On the basis of their stable isotope compositions as well as the seasonal variations, different groups of waters (precipitation, surface waters, groundwaters and mineral waters) as well as seasonably variable processes of mixing between these waters can clearly be distinguished. In addition, reservoir effects and infiltration rates can be estimated. In the northern part of the site an influence of uprising mineral waters within the Quaternary aquifers, presumably along a fault zone, can be recognized. Marginal infiltration from the Neckar River in the east and surface water infiltration adjacent to a steep hill on the western edge of the site with an infiltration rate of about one month can also be resolved through the seasonal variation. Quaternary aquifers closer to the centre of the site show no seasonal variations, except for one bore hole close to a for mermill channel and an other bore hole adjacent to a rain water channel. Distinct carbon isotope compositions and concentrations of DIC for these different groups of waters reflect variable influence of different components of the natural carbon cycle: dissolution of marine carbonates in the mineral waters, biogenic, soil-derived CO2 in ground- and surface waters, as well as additional influence of atmospheric CO2 for the surface waters. Many Quaternary aquifer waters have, how ever, distinctly lower δ13CDIC values and higher DIC concentrations compared to those expected for natural waters. Given the location of contaminated groundwaters at this site but also in the industrially well-developed valley out side of this site, the most likely source for the low δ13CDIC values is a biodegradation of anthropogenic organic substances, in particular the taroils at the site.

Opis:
The study was carried out in the wall of a cliff that formed as a result of erosional cutting in the western foreland of a moraine landform from the Pomeranian and Gardno phases (Upper Plenivistulian, Rowy-Ustka clifs; northern Poland). Individual lithostratigraphic units have been documented: glaciofluvial delta deposlts, Poddąbie Till, lacustrine-glacial Wytowno Formation (consisting of three facies: deltaic, lower diamicton, and upper diamicton), lacustrine deposits of the Orzechowo Formation with a thick peat layer, and aeolian series at the cliff crest. The Wytowno Formation deposits include the following lithologies: medium-grained sands, fine-grained sands, muddy sands, muds, silty clays, clays, varved clays, fine-grained multi-fraction deposits, and tills (Dębina Till). Very high inclination of the strata is the result of glaciodynamic deformation. The deposits were accumulated in a proglacial lake. They are characterized by mud and clay as well as sand and sand-muddy lithofacies. The vastness of the water body is evidenced by a considerable size of the delta, and by massive structures of the clay layers.

Flood-deposited, muds are characterised by considerable variability of their lithological characters. This variability reflects the development of the river forming the terrace, the geological setting of the drainage basin and the morphology of the flood plain. The lithological variability of the muds causes great vertical and lateral variability in the engineering geological parameters. Therefore all calculations based on mean values obtained from laboratory analyses are prove to error. The most reliable values of parameters are obtained from fieldwork "in situ".

Opis:
Closed depressions (CDs) are common forms occurring in the European loess belt. So far, investigations of CDs in Europe have suggested various natural or/and anthropogenic processes leading to their formation. The origins of CDs occurring in the loess areas of Poland have been the subject of few investigations, and their results have not clarified the problem. Most frequently, the age of CDs is linked with the post-glacial period, or the final stages of the formation of the loess cover. The investigations of CDs carried out in eastern Poland (Nałęczów Plateau) have so far revealed some patterns with regard to the morphometric characteristics and distribution of CDs on the regional scale. They also suggest the impact of thermokarst processes on the formation of the CDs. Five main lithogenetic types of sediment underlying the loess cover have been documented: glacial tills, clay and clayey loams, patches of glacial tills and sandy deposits, sands with gravels, and the bedrock. The relief under the loess cover has also been documented. The types of sediment as well as the relief under the loess cover have an impact on local differences of water content in the loess sediments. It was found that the variatiability of the geological conditions in the Nałęczów Plateau in the Pleistocene had an impact on the local variation of the ice content in the upper part of the former permafrost. This led to local predispositions for the development of thermokarst CDs during the Last Glacial. Areas with a high density of CDs have less permeable sediments (glacial tills, clay and clayey loams) and small relative heights under the loess cover. In the Pleistocene, these areas had higher ice content in the upper part of the permafrost. A model of thermokarst CDs development in the loess areas in eastern Poland is proposed. The model shows that the distribution and size of thermokarst CDs depends on the thickness of the loess cover as well as the types and relief of sediments underlying the loess. The development of thermokarst in the region studied may have consisted of multiple stages resulting in superimposed CDs. Between two and four stages of thermokarst CDs development can be distinguished on the Nałęczów Plateau. The two main stages occurred in MIS 4/3 (~58 ka or 55-50 ka Oerel and Glinde interstadials) and MIS 2/1 (~12 ka). These landforms may have developed also during the Denekamp Interstadial (32-28 ka) and ~15 ka. The present investigations indicate significant morphogenetic effects of permafrost melting on the contemporary relief of the loess areas.

This paper presents the test results of horizontal hydraulic conductivity (k) of fen peats from eastern Poland. Three fen peatlands in the Lubartów Plateau (3 objects marked as LP1, LP2 and LP3) and two in the Siedlce Plateau (2 objects marked as SP1 and SP2) have been selected. Studied objects represent valley bogs type and are similar in peat thickness, but different in the occupied area. They are also vary in terms of botanic compositions and basic physical and chemical parameters of peats. The BAT permeameter was used to in-situ measurements of horizontal hydraulic conductivity. Horizontal hydraulic conductivity of studied peats varies from 1.3×10-8 m/s to 1.1×10-6 m/s. The lowest values of horizontal hydraulic conductivity were observed for silted (high-ash) carbonate peats and amorphous or pseudo-fibrous peats, while the highest values were observed for unsilted (low-ash) non-carbonate peats of fibrous structure. The analysis of variability of horizontal hydraulic conductivity showed that in each case the lowest values were observed for the bottom of the studied profile. The study allowed to indicate the specific areas within the peatlands differing in permeability and identify the role of individual objects as natural geological barriers.

The paper presents the interpretation of a composite seismic profile recorded to 18 s TWT which crosses western Poland from the south to north. The interpretation is based on data along the profiles GB-2, GB-2B-96 and 25-III-82 collected between 1987 and 1996. Two reflection horizons bordering the crystalline crust have been recognized: in the top - SK, and in the base (Moho - M). The Caledonian complex is distinguished in the northern part of the profile GB-2 north of the Dolsk Zone. The results obtained allow determination of crustal structure down to the Moho. Several deep fault zones have been delimited (in the regions of Dolsk, Szamotuły and Trans-European Fault) which cut the entire crust. Crustal thickness ranges from approximately 30 km in the Palaeozoic platform up to about 40 km along the Trans-European Suture Zone.

Opis:
Fulfilling the binding national, EU and other international regulations and requirements on climate and energy implies significant growth of renewables share in the total mix of energy production in Poland. Low-temperature geothermal energy extracted with the use of the ground source heat pumps (GSHP) is an efficient and reliable source for space heating, cooling and seasonal thermal energy storage and recovery, thus it contributes to reduction of low emissions and improvement of air quality. GSHP effectiveness is to a high degree determined by local geological and hydrogeological settings, therefore identification of natural properties of the subsurface is crucial for appropriate design and subsequent operation of the GSHP installations. The thermal conductivity λ of rocks and soils, a key geothermal parameter, depends on such features as the mineral composition of rocks and soils, their texture and water content. Relevant geological data is retrieved from thematic databases, atlases and serial maps and can be gathered in a unitary database with a uniform structure to enable spatial analysis with the use of GIS techniques. Reclassification of lithological properties into geothermal parameters and subsequent calculations of λ values (W/m·K) of rock and soil types can be made using a specific algorithm. The results of these calculations enables computation of four spatial layers of average geothermal conductivity coefficient λ (W/m·K), respectively for the depth intervals of 0-40, 41-70, 71-100 and 101-130 metres b.g.l.

We show how geological and geophysical studies conducted in the Jasło Foothills, near Dukla, help constrain the genesis of two mounds, understood as heaped piles of earth, circular in plan view, located in Łęki Dukielskie (site 27 “Pod Kopcem”) and Dukla (site 7). Eleven hand auger holes yielded sediment samples for grain size analysis by laser (with a Fritsch apparatus). Hand auger holes were also made at sites in Wietrzno-Sośnina (site 29), and in Łęki Dukielskie (site 5). Three of the mounds (Łęki Dukielskie sites 5 and 27 “Pod Kopcem”, Wietrzno-Sośnina site 29) are revealed to be of natural origin, i.e. they are rock “lumps” covered with a thin layer of weathered silty-clay deposits. The fourth of the mounds (Dukla site 7) was found to have an anthropogenic origin; given its dimensions, it can be considered a late Neolithic Corded Ware kurgan. The geological analyses were complemented by GPR measurements, which supported the observations based on augering results.

Opis:
It has been increasingly realised that geological storage of CO2 is a prospective option for reduction of CO2 emissions. The CO2 geological storage potential of sedimentary basins with the territory of Slovakia, the Czech Republic, Poland, and the Baltic States is here assessed, and different storage options have been considered. The most prospective technology is hydrodynamic trapping in the deep saline aquifers. The utilisation of hydrocarbon (HC) fields is considered as a mature technology; however storage capacities are limited in the region and are mainly related to enhanced oil (gas) recovery. Prospective reservoirs and traps have been identified in the Danube, Vienna and East Slovakian Neogene basins, the Neogene Carpathian Foredeep, the Bohemian and Fore-Sudetic Upper Paleozoic basins, the Mesozoic Mid-Polish Basin and the pericratonic Paleozoic Baltic Basin. The total storage capacity of the sedimentary basins is estimated to be as much as 10170 Mt of CO2 in deep saline aquifer structures, and 938 Mt CO2 in the depleted HC fields. The utilisation of coal seams for CO2 storage is related to the Upper Silesian Basin where CO2 storage could be combined with enhanced recovery of coal-bed methane.

The densely populated northeastern Bulgarian Black Sea coast is a territory of intensive contemporary development. It is, though, marked by considerable recent geological activity along the coastal zone comprising: faulting, earthquakes, landslides, earthflows, rockfalls, ground subsidence, marine erosion and variations of sea level. These are locally exacerbated by the ongoing development, resulting in increased instability. Notably, a part of the coastline has been lost as a result of gravity sliding. Analysis of this recent geological coastal activity, including the landslides, earthflows and rockfalls of 1996-1997, needs be taken into account for the protection of the population and the cultural heritage.

Active geological processes are still observed on Gediminas Hill. The latest landslides appeared on March 22, 2004 and on March 8, 2008 on the eastern slope above the hiking trail, as well on February 11, 2016 and February 13, 2016 on the northern part of the slope. The latest landslide (involving ~40 m3 of soil) took place on March 7, 2017 between the eastern and southern slopes. Eight hydrogeological units were distinguished in 2017. During 2019–2020 many engineering geological and geotechnical investigations have allowed determination of the possibilities and methods of slope stabilization.

Opis:
Reservoir confinement by faults is important for safe storage of liquid waste or hydrocarbons. Having access to 3D seismic and borehole data, we have interpreted the tectonic setting of the Wysoka Kamieńska Graben (WKG) in the NW part of the Polish Basin and subsequently made an interpretation of the sealing potential of the graben-bounding faults. The formation and development of the graben in the Late Triassic and Early Jurassic was controlled by mechanical decoupling in the salts of the Zechstein Group. The primary tectonic factor triggering the graben origin was dextral strike-slip movement along the regional fault zone in the Paleozoic basement, transtensional accommodation of which in the Zechstein-Mesozoic cover led to development of a horse-tail pattern of grabens. During the Late Cretaceous, the graben underwent minor tectonic inversion. Sealing potential analysis of the graben-bounding faults was performed for the Triassic–Jurassic sequence including juxtaposition seal and fault gouge seal components. Finally, we have focussed our interpretation on the Jurassic sequence where the best reservoirs have been recognized. Our results indicate good to moderate sealing potential of the Hettangian reservoir, poor to moderate sealing of the Pliensbachian reservoir and lack of sealing of the Bajocian reservoir. Hence, the Hettangian reservoir, characterized by large thickness, low clay content and a large regional extent, acts as a potential storage formation, being confined by the graben-bounding faults of the WKG.
