The Permian/Triassic boundary in the Polish Basin in the light of paleomagnetic data

Abstract

Magnetostratigraphic studies were carried out to verify the sedimentological and lithostratigraphical Zechstein/Buntsandstein boundary in the Polish Basin. Samples were taken from three boreholes: Brojce IG 1, Mszczonów IG 1 and Jaworzna IG 1. Both boundaries fall within the zone of normal magnetization, which includes the uppermost part of the Top Terrigenous Series or the Rewal Formation. The results of paleomagnetical, sedimentological and palynological studies shows that the Baltic Formation of the Lower Buntsandstein may be correlatable with the Lower Griesbachian.
