Geological section through the lower Paleozoic strata of the Polish part of the Baltic region

Jędrzej Pokorski

Abstract


The present-day structural pattern of the Baltic Depression developed due to superimposition of three main deformation phases: syn-Caledonian (after the Silurian), syn-Variscan (at the end of Carboniferous and beginning of Permian) and syn-Alpine (latest Mesozoic or earliest Cenozoic). The major restructuring of the area occurred as a result of syn-Variscan deformation that took place in latest Carboniferous and earliest Permian times. Most of the faults developed or became reactivated probably at that time. Syn-Alpine deformation manifested itself relatively weakly, mainly by reactivation of some pre-existing faults.
