CONSOLIDATED BASEMENT OF THE KRAKÓW REGION IN THE LIGHT OF MAGNETOTELLURIC STUDIES – MAIN TECTONIC FEATURES

Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2010, Vol 443, Issue 443

Abstract

The study deals with the main tectonic features of consolidated basement in Kraków region. The authors used eight magnetotelluric profiles for the interpretation. The rock bodies of differentiated, usually high resistance, visible in the magnetotelluric profiles and occurring deeper than 5 km, were linked to the consolidated basement blocks of the Upper Silesian Block. Starting from the southeast the following blocks were identified: the Cadca and Cieszyn blocks, the Upper Silesian Block which encloses the former ones from the north and east, and finally the easternmost Rzeszotary Block. These slabs are separated by faults and discontinuity zones differing as to their significance and age. The dislocations likely developed on pre-existing Neoproterozoic faults. They were also subsequently active during a number of youngre orogenic cycles, including the Alpine one.
