Application of magnetic susceptibility for correlation
of the Lower Triassic red beds of the Baltic basin
Valentinas KATINAS, Jerzy NAWROCKI
Correlation of red beds by magnetic susceptibility is a new and cheap research method in Lithuania. Lower Triassic samples were collected from three boreholes of Lithuania and one well of Kaliningrad Region (Russia). Magnetic susceptibility of 687 samples was measured with a KLY-2 kapabridge. Having magnetic susceptibility data from the borehole Vladimirovo-1 (stratotype of lower Triassic sediments in the Baltic region) we can compare them to magnetic susceptibility data from the boreholes Galzdonai-1, Žvelsėnai-8 and Kernai-1. The result of the study is a new stratigraphical correlation of lower Triassic in the Baltic basin. Earlier it was supposed that all Triassic sediments in the boreholes Kernai-1 and Žvelsėnai-8 correspond to the Nemunas Formation, but the new data indicate presence of both the Nemunas and Palanga Formations.
