THE MAGNETISM OF SOME PERMIAN RED SANDSTONES FROM NORTHWESTERN TURKEY

Abstract

A series of eighteen oriented samples collected from the Permian of the Amasra region (Black Sea coast) revealed after progressive demagnetization a characteristic remanent magnetization vector with a declination of 290’ and an inclination of -14i”, as opposed to the declination of 210° and inclination of -159’ calculated for the same region on the basis of the mean Permian pole position as determined from samples obtained from stable parts of the European continent. Such deviations are a common feature of material collected from the neighbourhood of the alpine erogenic belt; in this instance the discrepancy is tentatively explained in terms of regional strike- slip faulting.
