Abstract

Abstract: The deep magnetic field characteristics in Qiangtang basin and Cuoqin basin of Qinghai-Ti-bet plateau is presented and analyzed by means of viewpoint of buried aulacogen. In terms of MT electrical shell depth map and Mesozoic subsiding belt thickness, the S-N normal magnetic anomaly belt(89°-90°at east longitude) is interpreted as a buried aulacogen of Late Paleozoic which is of important controlling effects on the structural units, depositions and hydrocarbon occurences of Mesozoic in northerm Qiangtang depression.
