| Abstract: | AMS studies earlier carried out on the flysch sediments from the Outer Western Carpathians focused on the sandstone members
deposited from turbidity currents. The main conclusion of these studies was that the dominant features of the AMS fabric developed
during sedimentation and the tectonic overprint was weak. In recent years a large number of claystone (deposited also from
turbidity currents, but in calm water) localities were sampled from the Krosno beds of the Silesian nappe, primarily for paleomagnetic
study. Nevertheless, the AMS of the samples was also measured. The magnetic fabrics of the claystones were dominated by foliation,
but lineations were also expressed and attributed to deformation. The question arose how different are the reactions of the
claystone and the siltstone beds to deformation. |
