PapaqakoP6 - 03 GRAVITY & MAGNETICS SOME RESULTS OF MAGNETIC REGIONAL SURVEY CARRIED OUT IN REHOVA-ERSEKA AREA Petrika Kosho Shpresa Dema Suzana Ballushi Mimoza Papaqako Geophysical Center Of Tirana Albania Introduction The geology of Rehova – Erseka area consists of magnetic and sedimentary rocks. They belong to the structural – facial zones of Mirdita and Krasta-Cukali (subzone of Krasta and Gramozi). The sedimentary rocks predominate against the magmatic ones. The magnetic rocks and the carbonatic formations of Trias-Jurasic of continental margins with their sedimentary cover have been distinguished in the Mirdita zone.
