Abstract

CONSOLIDATED BASEMENT OF THE KRAKÓW REGION IN THE UGH? OF MAGNETOTELLURIC STUDIES - MAIN TECTONIC FEATURESAbstract. The study deals with the main tectonic features of consolidated basement in Kraków region. The authors used eight magnetotelluric profiles for the interpretation. Hie 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 Siiesian Block. Starting from the southeast the following blocks were identified: the Ćadca and Cieszyn blocks, the Upper Siiesian 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 younger otogenic cycles, including the Alpine one.
