Budowa geologiczna oraz geneza i ewolucja bloku Gorzowa

From the beginning of geological investigations of the Polish Lowlands both the geological and the regional tectonic units were used simultaneously. The Szczecin-Gorzów Synclinorium should be distinguished in terms of tectono-structural rules. The Gorzów Block - as a geological unit - is defined on the basis of extent and differentiation of the Upper Cretaceous thickness or by distribution of local structures (mainly halotectonic and halokinetic ones) developed in the Zechstein-Mesozoic complex. Basement in the Gorzów Block area is uplifted in its consolidated part and also the top of Moho is elevated. Both uplifts are well correlated with the Permian-Mesozoic palaeogeothermal anomaly. The Gorzów Block incorporates also the north-western part of Wolsztyn Ridge which was active during the Permian-Mesozoic time. In the early Rotliegend time this area was characterized by volcanic activity. In the late Rotliegend it was a source for clastics deposited around the Wolsztyn Ridge. Also the carbonate platform facies of the Main Dolomite (Ca2) is associated with this uplifted area. The mentioned region is situated in the distal part of asymmetric, Polish rift basin. Development of basin analysis - as an interdisciplinary domain of the Earth Sciences - indicates the need of applying various geological units, adequate to the considering problem. Modern research methods in geology (computerization, GIS) enable the data bases creation for individual geological units necessary for study of their origin and evolution up to their present geological pattern.
