Inversion Tectonics Vs. Depositional Systems – Seismic Examples Of The Upper Cretaceous Succession From Poland
Abstract
The transition from an extensional to a compressional stress regime in Europe during the Late Cretaceous/Paleogene led to the reverse reactivation of normal faults and the uplift of basement blocks along with their extension-related sedimentary cover. This regional inversion also triggered the compressional reactivation of salt structures. In my talk, I will discuss high-end 2D seismic reflection data from the vicinity of the main inversion structure in Poland, i.e. the Mid-Polish Anticlinorium, which provide evidence of the significant impact of inversion tectonics on Late Cretaceous depositional patterns in the study area. The seismic examples, presented in my talk, will document the depositional architecture shaped by transverse and axial depositional systems, adjacent to salt structures developed within the sedimentary cover of the Paleozoic platform and inversion structures within the East European Craton (EEC). These structures functioned both as morphological barriers and as alimentary areas for the Polish Basin. The development of depositional architecture in NE Poland may have also been influenced by the lithospheric buckling along the southwestern margin of the EEC, which I will discuss as well.
