RESULTS OF PALEOMAGNETIC STUDY OF TRIASSIC FORMATIONS IN THE CENTRAL URALS,

Abstract

The study of the rocks in question was carried out by the Experimental Methods Group of the Urals Geological Directorate, using samples from Central Transuralia collected on the banks of the Sinara, Pyshma, Bobrovka and Bichur Rivers. The magnetic susceptibility of the basalts varies in the mean from 500 to 3000.0.000001 CGSM. Attention was given to studying the magnetic stability of the rocks and to the methods of magnetic cleaning. The remanent magnetization of many Uralian rocks showed itself to be a viscous magnetism. Only basalts, porphyrites of basaltic composition, diabases, orthophyres and red argillites were found to be magnetically stable. But even in these rocks, particularly when taken from natural outcrops, we often find samples partially or entirely remagnetized. Consequently for paleomagnetic research in the Urals a particular importance attaches to methods of magnetic cleaning, which permit the primary remanent magnetization to be separated out. (Author)
