ALTERNATING FIELD DEMAGNETIZATION STUDY ON LOWER SINIAN SANDSTONES IN XIUNING (HSIUNING) DISTRICT, ANHUI (ANHWEI) PROVINCE.

Abstract

This paper presents the results of magnetic stability testing, by alternating current demagnetization, of some orientated Lower Sinian sandstone samples from the Xiuning formation in Xiuning District, Anhui Provice. The results show that the natrual remanent magnetization of the formation is stable, and its mean direction is determined as D sub r = 311 degrees and i sub r = 76 degrees. Thus the position of the paleomagnetic north pole in this era is inferred to be 90 degrees E and 45 degrees N, and the paleolatitude of the sampling site was 63 degrees. The paper confirms the importance of the alternating current demagnetization test for paleomagnetic research. Finally, some views are expressed on the study of the local climatic conditions during the Early Sinian period. (Author)
