摘要: Paleomagnetic results from numerous Early–Middle Devonian volcanic sequences of the Minusa trough, southern Siberia, are presented. The analysis these data definitely indicates that geomagnetic field in had a specific character, different both present and more ancient geological epochs, was extremely variable (hyperactive). anomalies paleomagnetic record not local, peculiar to particular region, but have global occurrence. synthesis obtained with coeval volcanics Scotland shows during relatively short time (10–20 Ma), pole repeatedly changed its location, significantly deviating Earth’s rotation axis up (paleo)equator assuming some quasi-stable positions. arguments suggesting features could probably be induced by significant contribution equatorial dipole main
