Opis:
The Kupferschiefer (T1) records a period of basin-wide euxinic conditions, and is thus considered an excellent time-marker in the Zechstein (Lopingian) basin. Previous studies indicated that both the Kupferschiefer and Marl Slate and the overlying Zechstein Limestone (Magnesian Limestone) show remarkable changes in carbon isotopic composition towards higher 131313131313

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 M-29 exploratory borehole and operating well is located on the Mogilno I deposit in the south-eastern section of the Mogilno Salt Dome (Fig. 2). It was drilled down to the depth of 1,751 m in 2014. The borehole penetrated the evaporites of the Upper Permian (Zechstein) and a sequence of clay-mudstone-sand formations of the Lower Triassic. 11 lithostratigraphic members of the Zechstein salt series, belonging to cyclothems PZ-2, PZ-3, and PZ-4, were separated in the core subjected to our analysis. The salt deposit of the borehole M-29 area had been formed tectonically. The borehole cuts through a deep syncline, filled with the sediments of cyclothems PZ3 and PZ4. The syncline is limited on the ceiling and floor sides by anticlines composed mainly of Na2 rock salt. As a result of the uplift of the two anticline intrusions, the salt layers became strongly folded and formed very steeply. The borehole pierces through the same members several times. Many divisions are reduced in thickness or completely wedged out. No ceiling layers of cycle PZ-4 or evaporites, being older than Older Halite (Na2), were found in the profile. As a result of halokinetic and tectonic deformations, the salt layers became extremely folded and steeply arranged. The layer dip varies from 35° to 90°, mostly 60-80°. Numerous changes of the dip angle and multiple folding are demonstrated by the fact that the borehole often penetrated the same members.
Otwór badawczo-eksploatacyjny M-29 jest zlokalizowany w południowo-wschodniej części wysadu solnego Mogilno, na złożu Mogilno I (Ryc. 2). Został on odwiercony w 2014 r. do głębokości 1751 m. Otwór nawierca ewaporaty późnego permu (cechsztynu) oraz kompleks utworów ilasto-mułowcowo- piaszczystych dolnego triasu. W analizowanym rdzeniu wydzielono 11 ogniw cechsztyńskiej serii solnej cyklotemów PZ-2, PZ-3 i PZ-4. Złoże solne w rejonie otworu M-29 jest uformowane tektonicznie. Otwór przewierca głęboką synklinę, wypełnioną osadami cyklotemów PZ3 and PZ4. Synklina ograniczona jest od stropu i spągu antyklinami, zbudowanymi głównie z soli kamiennej Na2. W wyniku wypiętrzenia tych dwóch intruzji antyklinalnych warstwy solne zostały silnie sfałdowane i zalegają bardzo stromo. Otwór przewierca kilkakrotnie te same ogniwa. Wiele wydzieleń jest zredukowanych lub całkowicie wyklinowanych. W profilu nie stwierdzono warstw stropowych cyklu PZ-4 i ewaporatów starszych niż Starszy Halit (Na2). W wyniku deformacji halokinetycznych i tektonicznych warstwy solne są silnie pofałdowane i zalegają bardzo stromo. Upad warstw waha się od 35 do 90°. Najczęściej jednak wynosi 60-80°. Otwór przewierca wielokrotnie te same ogniwa ze względu na częste zmiany kąta upadu i przefałdowania.

Opis:
Otwór badawczo-eksploatacyjny M-35 jest zlokalizowany w południowo-wschodniej części wysadu solnego Mogilno (Ryc. 2). Został odwiercony do głębokości 1755 metrów. Otwór nawierca ewaporaty późnego permu (cechsztynu). W analizowanym rdzeniu wydzielono 13 ogniw cechsztyńskiej serii solnej cyklotemów PZ2, PZ3 i PZ4. Złoże solne w rejonie otworu M-35 jest uformowane tektonicznie. W wyniku procesów halokinetycznych i halotektonicznych warstwy solne zostały silnie sfałdowane i zalegają bardzo stromo. Upad warstw waha się od 35 do 90°. Najczęściej jednak wynosi 70-80°. W wyniku częstych zmian kąta upadu i przefałdowań otwór przewierca kilkakrotnie te same ogniwa. Ponadto wiele wydzieleń jest zredukowanych lub całkowicie wyklinowanych. W profilu nie stwierdzono warstw stropowych cyklotemu PZ4 i ewaporatów starszych niż ogniwo starszej soli kamiennej (Na2).
The M-35 exploratory borehole and operating well is located in the south-eastern part of the Mogilno Salt Dome (Fig. 2). It was drilled down to the depth of 1,755 m penetrating the Upper Permian (Zechstein) evaporates. Its core section enabled to distinguish 13 lithostratigraphic members of the Zechstein salt series, represented cyclothems PZ2, PZ3, and PZ4. The observed salt units had been tectonically extremely folded and steeply arranged. The layers dip varies from 35° to 90°, mostly 70-80° and the same salt units repetated several times in the section. Also many of them were reduced in thickness or completely wedged out. The uppermost units of PZ4 cycle or evaporates older than the Older Halite (Na2) unit, were not found in the studied profile.

Opis:
The Polish Zechstein Basin was a tideless sea dominated by storms. Main Dolomite deposits of the Miedzychód region were deposited: a) on the carbonate platform (in the environments of the outer barrier, inner barrier and high- and low-energy platform flat); b) on the platform slope; c) at the toe-of-slope; d) on the basin floor. The best reservoir properties are recorded in shallow-marine deposits of the outer and inner barriers and in deep-sea sediments of the toe-of-slope (turbidites and debrites). Rich reserves of crude oil and natural gas were discovered both on the carbonate platform (the Miedzychód and Grotów deposits) and at its toe-of-slope (the Lubiatów deposit). The Main Dolomite sediments are wholly included in the second depositional sequence (PZS2 sensu Wagner & Peryt, 1997). The maximum flooding surface of the PZS2 sequence within the platform, its slope and toe-of-slope, runs along the A1g/Ca2 boundary. In the basinal zone, its correlative equivalent is a hard ground observed within the Main Dolomite carbonate rhythmites. The boundary between the second and third (PZS2/PZS3) depositional sequences (corresponding to the ZS3/ZS4 sequence boundary in the German Basin) runs on top of the Main Dolomite carbonates (on the platform slope, at the toe-of-slope and on the basin floor) and above top of the Main Dolomite carbonates, within the lower part of the Basal Anhydrite (on the platform).

Opis:
W utworach ewaporatowych występuje wiele minerałów akcesorycznych, nierozpuszczalnych w wodzie, które można łatwo wydzielić poprzez rozpuszczenia tych osadów. Z próbek pobranych z soli kamiennych, potasowo-magnezowych i zubrów wysadu solnego Kłodawa wydzielono w efekcie hydroseparacji nierozpuszczalne w wodzie residuum, w którym stwierdzono obecność idiomorficznych monokryształów: anhydrytu, hydrotalkitu siarczanowego, magnezytu, dolomitu, kalcytu, boracytu, kongolitu, kwarcu, hematytu, pirytu, siarki, oraz mikrokrystaliczne skupienia szajbelyitu, talku, mik i chlorytów. Większość z tych minerałów występuje jednocześnie w różnych warstwach profilu. Nieliczne z nich wykazują bardzo wąski zakres koncentracji dotyczący wyłącznie określonej warstwy lub części pokładu, tworząc swego rodzaju poziomy mineralne. Należą do nich: kwarc i kalcyt z wrostkami bituminów, boracyt, szajbelyit, talk, hydrotalkit siarczanowy i kongolit. Na podstawie ich występowania wydzielono w kłodawskim wysadzie solnym pięć poziomów mineralnych. Mogą one być nowym narzędziem do identyfikacji oraz korelacji litostratygraficznej pokładów i warstw w cechsztyńskich złożach soli.
Evaporate formations include a number of accessory minerals that are insoluble in water. They can be easily separated by dissolving sediments. The samples collected from rock, potassium-magnesium and zuber salts of the Kłodawa salt diapir were subjected to hydro-separation to obtain insoluble residuum in which the presence of idiomorphic monocrystals was found: anhydrite, sulphate hydrotalkite, magnesite, dolomite, calcite, boracite, kongolite, quartzite, hematite, pirite and sulphur, as well as microcrystalline concentrations of szaibelyite, talc, mica and chlorites. The majority of those minerals occur in various section layers at the same time. Few of them display a very narrow scope of concentration relating to exclusively specific layer or part of the stratum, creating specific mineral layers. They include: quartz and calcite with the ingrowths of bitumen, boracite, szaibelyite, talc, sulphate hydrotalkite and kongolite. Based on the occurrence of those minerals, five mineral levels were identified in the Kłodawa salt diapir. They can present a new tool for lithostratigraphic identification and correlation of strata and layers in Zechstein salt deposits.

Opis:
The sedimentary and stratigraphic patterns established for Zechstein of the western part of the Peribaltic Syneclise (and in particular the eastern Łeba Elevation) were applied to other parts of the East European Craton (EEC) in Poland: the eastern Baltic Syneclise and the Podlasie region. A very large number of mostly fully-cored borehole sections in the Puck Bay region certainly predestines the eastern Łeba Elevation area to use it as a model. The most part of the EEC, except of its part adjacent to the Teisseyre-Tornquist Zone, during the Zechstein deposition represents the marginal parts of the basin. The fauna occurring in the Zechstein carbonate deposits of the EEC makes it possible to distinguish between the Zechstein Limestone and the younger carbonate strata, but certainly not between the Main Dolomite and the Platy Dolomite and hence the facies models for the Zechstein that have been previously developed in the western part of the Peribaltic Syneclise augmented by sequence stratigraphic approach seem to be the best tool to apply in other peripheral areas in the EEC area. The Zechstein sequence in the western part of the Peribaltic Syneclise consists, in general terms, of three parts: (1) carbonate platform of the Zechstein Limestone (occurring only in the north-westernmost corner of the study area and passing into basin facies dominant in the most part of the area); (2) the PZ1 evaporite platform system composed of sulphate platforms and adjacent basin system and constituting the major part of the Zechstein sequence; and (3) the Upper Anhydrite-PZ3 cover. There is a consensus, as far as the western part of the Peribaltic Syneclise is concerned, that the Platy Dolomite platform is wider than the Main Dolomite platform. In the easternmost part of the Peribaltic Syneclise, the stratigraphical interpretations are diverse. We have included the anhydrite overlying the Zechstein Limestone into the Upper Anhydrite, and concluded that the overlying interbedded mudstone and anhydrite also belong to the Upper Anhydrite. When above the Upper Anhydrite one carbonate unit occurs, it is assigned either to the Main Dolomite and Platy Dolomite, or to the Platy Dolomite. The same conclusion is proposed for the marginal parts of the Podlasie Bay. The deposition of Zechstein Limestone resulted in the origin of carbonate platforms along the basin margins which changed an inherited topographic setting. The Lower Anhydrite deposits are lowstand systems tracts (LST) deposits, lacking in more marginal parts of the western and eastern Peribaltic Syneclise and in the major part of the Podlasie Bay. The accommodation space existed and/or created during the Lower Anhydrite and the Oldest Halite deposition in the Baltic and Podlasie bays was filled and at the onset of the Upper Anhydrite deposition, a roughly planar surface existed except in the area adjacent to the main Polish basin. The Upper Anhydrite deposits are transgressive systems tracts deposits and then highstand systems tracts deposits and they encroached the Zechstein Limestone platforms. The Upper Anhydrite deposition was terminated by sea level fall, and the Upper Anhydrite deposits in the marginal areas became subject to karstification. The Main Dolomite transgression took place in several phases but its maximum limit did not reach the Upper Anhydrite limit. The deposition of the PZ2 chlorides (LST deposits) resulted in the filling of the accommodation space that was inherited after the deposition of the Main Dolomite and the Basal Anhydrite. Subsequently, the area became exposed, and marine deposits (Grey Pelite and Platy Dolomite) related to the last major transgression during the life of the Zechstein basin that resulted in a flooding of the exposed surface of older Zechstein deposits, including the area that was emergent during deposition of the PZ2 cycle. Microbial carbonates, being stromatolites and thrombolites, are a common feature of all Zechstein carbonate units but in particular this is the case of the Platy Dolomite. There are no direct premises allowing for convincing settlement doubts regarding the stratigraphical position of the upper carbonate unit in many cases, but several lines of evidence suggest that, as in the entire Zechstein basin, the Main Dolomite considerably shifted basinward, and the Platy Dolomite – landward, although it is difficult to ascertain whether the original Platy Dolomite extent was similar to or greater than the limit of the Zechstein Limestone as elsewhere in the Zechstein Basin.
