Abstract

The results of palaeomagnetic studies of the Volyn trap formation and red beds of Podillia are presented. The geomagnetic field’s anomalous behavior is confirmed, manifested in the discrepancy of paleomagnetic poles of the same age, a hyperactive mode of field polarity change, and extremely low values of field palaeointensity. These may be related to the problems of palaeogeographic reconstructions in the Ediacaran, as well as the drastic influence of geomagnetic conditions on the environment and biota evolution.
