Opis:
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:
Palaeomagnetic research on the lower and middle Buntsandstein section of the Gorzów Wielkopolski IG 1 borehole, located in middle western Poland, showed the possibility of existence of short reversed subzones within the first normal polarity zone of the lowermost Buntsandstein (magnetozone Tbn1). The earlier established magnetozones Tbn2 and Tbn4 were not detected. The stratigraphic gap between the middle and upper Buntsandstein included at least magnetozones Tbn6 and Tbr6. The magnetostratigraphic correlation between the investigated section and the Otyń IG1 section indicates a substantial diachronism of palynostratigraphic zones based on macrospores in the lowermost and middle Buntsandstein.

Opis:
The trepostome bryozoan Dyscritella microstoma Ernst, 2001 is reported for the first time from the Zechstein Main Dolomite (Ca2) of Poland and Germany. This species has been previously recognized in the older fossiliferous Zechstein Lime stone (Ca1) of the North Sudetic Basin (Poland) and in the northern part of Germany. The Polish specimens derive from a few boreholes located in the Pomerania region and in the Wolsztyn High, both in the western part of Poland. The German material comes from a borehole on Rügen Island in North eastern Germany. The present paper deals with the taxonomic description of D. microstoma and its distribution in the Main Dolomite deposits.

Opis:
The Białowice site is situated in the north-west of the Nowa Sól Depression which is part of the Central Poland Lowlands. Palynological analysis shows that lake and swamp accumulations took place in the Early Vistulian. Two warm interstadial-rank oscillations (Brörup and Odderade) and a stadial (Rederstall) have been distinguished during the Early Vistulian. The sequence of changes at Białowice is similar to the sequences in profiles from other parts of Poland and Western Europe. Until now, in that region of Poland the vegetation succession of the Brörup and Odderade had remained unknown. The lithology of the profile at Białowice shows rapid changes of sedimentation which have been observed in the younger part of the Brörup and at the Brörup/Rederstall transition. Geological and palynological data suggests that the maximum limit of the Vistulian Glaciation to the south of the Żary Hills.

Opis:
The Mid-Polish Trough (MPT) is well recorded in the distribution of thickness of the Mesozoic sediments. Its shape was most distinctly delineated in the Early Triassic, and Early to Middle Jurassic, when thickness gradients attaining 100 m/km were reached. However, because the regional faults bordering the MPT were not active throughout its history, the existence of Mid-Polish Rift has not been confirmed. The strongest thickness gradients may have been caused by the periodical activity of the sub-Zechstein faults, which did not penetrate the Mesozoic strata due to the damping effect of plastic Zechstein salts. On the contrary, local faults, forming (mainly during the Late Triassic) syn-sedimentary grabens, are a common feature in the MPT and its surroundings. Transversal subdivision of the MPT and its slopes into at least two segments (Pomeranian and Kuiavian) is clearly visible in the thickness pattern. It is expressed by the presence of separate depocentres, reversal of asymmetry, differences in stratigraphical sequences observed on the palaeomorphological terraces south-west of the MPT, and by the structural variations after the inversion. The scale of inversion, which transformed the MPT into the Mid-Polish Swell (MPS), is unclear and needs further investigations. Estimation of the thickness of the Upper Cretaceous sediments removed by erosion is a key problem in this respect. It should take into account both, the effects of the regional inversion and the local changes resulting from the last stage of strong salt displacements.
