Zechstein Limestone
Opis:
The entire Zechstein Limestone section of the Zdrada IG 8 borehole (Northern Poland) is composed of oncoid packstone that is accompanied by stromatolites in the upper part of the unit. Deposition of the Zechstein Limestone occurred in persistently subtidal environments, above the storm wave base, in mostly dysoxic conditions, and thus these conditions did not differ essentially from those characteristic for the Kupferschiefer strata. The previous supposition of vadose diagenesis is not confirmed by the isotopic study of calcite that showed its clearly marine values (average d1318

Opis:
The paper presents the critical opinion expressed by Osiejewicz (2018b) who supports the view of Legislative Council of26 January 2018 on the draft act on the Polish Geological Agency that the German federal geological survey (Bundesanstalt fur Geowissenschaften und Rohstoffe - BGR) can be considered as an appropriate formula for the Polish Geological Institute - National Research Institute (PGI - NRI). This opinion is groundless and ignores the fact that because of the federal nature of FRG, many tasks of the national geological survey can, and are, accomplished by the state geological surveys only, and cannot be realized by BGR. PGI-NRI in turn accomplishes tasks of both BGR and the state geological surveys and in addition, possesses bigger potential to undertake new tasks.

Opis:
The Gorzów Block (West Poland) occurs in the transition zone between the PZ1 sulphate platform and the Na2 basin. In contrast to the western part of the Southern Permian Basin where the Z1 halite (Oldest Halite Na1) is normally restricted to the peripheral subbasins located south of the main basin, in Poland it occurs both in the basin centre and in the former basins of the Lower Anhydrite within the marginal sulphate platform complex, where halite sequences are thick and may have originated in a deep-water setting. The Na1 deposits have been considered so far to be LST deposits both in the marginal sulphate platform facies as well as in the basin centre. Brine salinities (and the minerals they precipitate) are controlled by brine residence times in the basin, and these are determined primarily by the absolute and the relative rates of water flow into, and brine flux out of the basin (Kendall, 2010). Thus sea-level rise in the Boreal Sea could have resulted in the increase of the brine residence times in the Zechstein basin and the deposition of more saline evaporites. Consequently, the Oldest Halite in the basin centre in Poland is regarded as the TST deposit.

Opis:
The Hanover declaration (1993) of the mission of a geological survey clearly states that it does not deal with management, but as a government organization it should serve the state authorities and societies by scientific advice and information on natural resources and the environment, and such a mission can be accomplished only by science, methodological competence and research independence. More than a half of the geological surveys in EU countries define themselves as research institutions (Fig. 1), and the scientific production expressed in the ratio ofpublications in JCR journals per staff number in some geological surveys (e.g. ČGS, BGS) is bigger than in the Polish Geological Institute-NRI (Fig. 2) what in part is related to the role played by sendee tasks of the PGI-NRI. The close connections of geological surveys with the scientific research are ignored by adherents of establishment of the Polish Geological Agency.

Opis:
Most western geological surveys, and in particular European Union countries and the USA, focus on public-good science for government, and research to understand earth and environmental processes, in order to supply neutral and independent advice and information about all geoscientific and natural resources issues to the government and society. In contrast, the current draft law on the Polish Geological Agency aims at introducing coherent hydrogeology and geology management as well as implementation of state policy in the field of resources security. Thus, the conclusion that the Polish Geological Agency is an analog of geological surveys, existing in many other developed countries, is absolutely unjustified.

Opis:
The Polish Geological Institute was established in 1919 as the national geological survey within the Ministry of Industry and Trade. The initiative of a group of parliament members to appoint the Polish Geological Institute was supported by the Polish Parliament on May 30, 1919, and the official opening of the Institute took place on May 7, 1919. Two years later the PGI status and budget were accepted by the Polish government and Józef Morozewicz has received director’s nomination from the Head of State Józef Piłsudski. In March 1938, the President of Poland accepted a new decree concerning geological survey of Poland which was composed of the Polish Geological Institute and the State Geological Council. The role of the PGI grew and the budget substantially increased, but this positive trend was stopped due to the beginning of World War II. During the first post-war years, regional and basic studies made it possible to establish a geological model of Poland leading to great discoveries of mineral deposits in the fifties. The decree of October 8, 1951 adjusted the organization forms of the geological survey to the system of central planning and the domination of state property, and the institute (with the name changed to the Geological Institute) became a scientific institution. During the first years the institute experienced good conditions of development, and a great progress in the knowledge of geology of Poland combined with the basic and regional studies that led to significant discoveries and documentation of mineral deposits. However, already in the seventies the first signs of crisis in geology became evident. In 1985, the Ministry of Environmental Protection and Mineral Resources was established, the Central Board of Geology was disbanded, and many tasks of geological survey returned to the institute, hence this turned out to be appropriate to return to the historical name, Polish Geological Institute, which took place on June 19, 1987. Since January 1, 2012, the Polish Geological Institute has served as the Polish geological survey on the basis of the Act of June 9, 2011, and earlier, since January 1, 2002, legally specified tasks of the Polish geological survey has been assigned to the PGI. On February 24, 2009 the Council of Ministers gave the PGI a status of National Research Institute, and this implied the adding this new status to the name of the Polish Geological Institute. For the century the Polish Geological Institute has successfully fulfilled all the basic responsibilities and commitments that are conventionally assigned to national geological surveys, and is a model example of modern national geological survey of very wide expertise.

Carpathian Foredeep
Opis:
Badenian evaporites of the Carpathian Foredeep Basin represent the lower part of the NN6 zone and are underlain and overlain by deep-water deposits. Halite and associated deposits in the central part of the Badenian evaporite basin show the same facies successions and marker beds can be traced across and between individual basins. Characteristic marker beds made it possible to correlate various facies zones of the marginal Ca-sulfate platform. These marker beds seem to reflect events that may be related to sudden and widespread changes in water chemistry, which in turn imply major changes in basin hydrology. The onset of the evaporitic deposition in the Carpathian Foredeep was clearly diachronous and the evaporites deposited in the basin centre preceded the beginning of evaporite sedimentation in the marginal basin, however, depositional history in the marginal basin and the basin center was the same. Sedimentological and geochemical data indicate recycling of evaporites throughout most of the evaporite deposition.

Skład i zmiany zespołów otwornic pochodzących z najwyższej części utworów podewaporatowych w otworze wiertniczym Busko (Młyny) PIG-1 (głęb. 188–192 m), zlokalizowanym w północnej części zbiornika przedkarpackiego (Paratetyda Środkowa), wskazują, że zbiornik, w którym powstawały osady margliste, był słabo wentylowany, z dużym deficytem tlenowym w wodach przydennych oraz ze środowiskiem eutroficznym w wodach powierzchniowych. Zbiornik ten, o głębokości 50–70 m, wypełniały wody chłodne o zasoleniu typowym dla zbiornika morskiego. Obserwowane w najwyższej części profilu prawie całkowite wyeliminowanie otwornic Uvigerina i zajęcie na krótko zwolnionej niszy przez Fursenkoina acuta (zespół D4c) oraz zdominowanie składu najmłodszego zespołu (D4d) przez tolerującą podwyższone zasolenie Bulimina elongata może jednak wskazywać na znaczne podwyższenie zasolenia w trakcie depozycji najwyższej części utworów poprzedzających depozycję gipsów. Profil gipsów badeńskich w badanym otworze wiertniczym w porównaniu z bardziej brzeżną strefą platformy gipsowej cechuje się redukcją dolnej, autochtonicznej części gipsów oraz specyficznym wykształceniem najniższej jednostki gipsów. W matriksie ilastym występują tam gruzły gipsu bardzo przypominające małe, chaotycznie ułożone blokowe zrosty krystaliczne, określane jako facja szkieletowa gipsów szklicowych, związana w niecce Nidy oraz na Morawach z obniżeniami dna. Wykształcenie profilu gipsów wskazuje na głębsze środowisko sedymentacji niż to stwierdzono w rejonie niecki Nidy.
Composition and changes in foraminiferal assemblages recorded in the uppermost part of the sub-evaporite deposits of the Busko (Młyny) PIG-1 borehole (depth 188–192 m) in the northernmost part of the Fore-Carpathian Basin (Central Paratethys) indicate that the basin, in which marly deposits have originated, was poorly ventilated with a great oxygen deficit in the bottom waters, and was characterised by mainly eutrophic conditions in surface waters. The basin was 50–70 m deep. The waters were cool and of normal seawater salinity, although the recorded (in the uppermost part of the section) almost complete disappearance of Uvigerina foraminifers, occupation (for a short time) of the vacant niche by Fursenkoina acuta (assemblage D4c), and the dominance of Bulimina elongata (tolerant to increased salinity) in the youngest assemblage (D4d) may indicate a considerable increase of seawater salinity during the deposition of the uppermost part of the sub-evaporite strata. The gypsum section is characterised, when compared to the more marginal gypsum sections of the Nida Trough, by a reduction of the lower, autochthonous part of the gypsum section and a specific development of the lowermost gypsum unit. It contains gypsum nodules resembling small, chaotically arranged gypsum intergrowths in the clayey matrix. Such facies is regarded as the skeletal facies of the giant gypsum intergrowth facies of the Nida Trough and Moravia, and is related to depositional lows at the beginning of the gypsum deposition. The gypsum sequence in this borehole indicates a deeper sedimentary environment than inferred for the Nida Trough.

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:
Established a few months after regaining independence in 1918, the Polish Geological Institute was carrying out research aimed at ensuring the supply of necessary mineral raw resources to the domestic industry. The director of the Institute, Prof. J. Morozewicz as well as the state authorities were aware of the fact that for the proper functioning of the Institute suitable headquarter was needed. Therefore, already in the mid-1919, the appropriate area and financial resources were allocated for the construction of large buildings, the designer of which S W0łk0wicZ T M Pervt was Prof. M. Lalewicz. The laboratory pavilion was opened in 1926. The main building, which was put into use in 1936 and rebuilt after the destruction during World War II, has been the pride of the Institute until today. The extension of the state and a wide range of research issues meant that already in 1921, it was necessary to establish the Upper Silesian Station in Dąbrowa Górnicza, whose activity was focused on the coal geology. The Geological Station in Borysław, operating in the structure of the PGI since 1920, was transformed three years later into the Oil and Salt Department of the PGI, which closely co-operated with the Carpathian oil industry. The Holy Cross Mountain research group was located during 1937-1955 in the family home of Jan Czarnocki. After World War II, due to the significant intensification of geological research and exploration in Poland, new regional divisions of the Institute were established that currently have their headquarters in Kraków, Sosnowiec, Wrocław, Kielce, Gdańsk and Szczecin; all have the rank of branches. The organizational structure of the PGI is of an extremely regional nature, and the research issues of individual branches are mostly related to the recognition of the geological structure and mineral resources occurring in a given region. In addition, the Polish Geological Institute possesses 8 core repositories.

The objective of this paper is determination of the geological and geochemical conditions, 1-D and 2-D modelling of petroleum processes and petroleum systems and their influence on the prospectives of hydrocarbon exploration of the Miocene strata in the Polish and Ukrainian Carpathian Foredeep and its Palaeozoic–Mesozoic basement. In particular, a coherent model of geological structure of the area, based both on the synthesis of the earlier published data and on new results of palynological studies of the Upper Precambrian and Lower Palaeozoic, is given. New data on microfacies of the Upper Jurassic and Lower Cretaceous strata and on sedimentology, geochemistry and micropalaeontology of the Middle Miocene rocks are presented.

Opis:
Strontium isotope ratios have been determined on 74 anhydrite samples from seven borehole cores in the Polish Zechstein. Five of the borehole cores are located in the basin and isotope results from these samples show a nearly pure marine signal. Results from one borehole core, located near the Zechstein coastline that migrated through time, record a stronger, in consistent influence of continental strontium to a marine base. Intermittent meteoric influence is recorded in anhydrites from other borehole cores close to the carbonate platform that was emergent during the anhydrite deposition. Consistency of isotope values indicates a marine signal and there is a narrow range in consistent values from 87Sr/86Sr near deltasw –215 (0.70702) for the oldest anhydrites and near deltasw –205 (0.70712) for the youngest an hydrites. Comparison with a sea water 87Sr/86Sr curve based on samples in West Texas and a Permian-Triassic boundary value from China shows that the Polish Zechstein in these seven boreholes is latest Permian in age and major deposition represents a short time interval (~2 million years). Strontium isotope ratios reported by other workers indicate some of the younger Zechstein elsewhere indicate even greater continental influence is in agreement with the interpreted sedimentological set ing for those anhydrites.

Opis:
Neptunian dykes were recently recorded within the Middle Miocene (Upper Badenian and Lower Sarmatian) Medobory reef complex of the Carpathian Foreland in western Ukraine. The Upper Badenian reefs are cut by a regular, semi-perpendicular network of intersecting fissures that penetrate the Badenian reef limestone down for more than 10 m. The dykes are filled by several generations of Sarmatian microbialites coating the fracture walls and by bedded bioclastic sediment (including foraminifers) which is more important volumetrically. The fissure fillings containing both the Sarmatian material as well as rare clasts of Badenian rocks indicate that the fissures were open during the onset of Sarmatian deposition. They originated following the emergence and fracturing of the Badenian limestones, either due to fault tectonics at basin margins induced by basin subsidence, around the Badenian-Sarmatian boundary, or to gravitational instability of large lithified Badenian reef bodies. Only one phase of fracture opening occurred. The filling of fractures was episodic, with pulses of cementation and microbial growth and sediment injection. Four different foraminiferal assemblages recorded in the neptunian dykes indicate that the process of fracture filling was long-lasting.
