PALAEOMAGNETIC STUDY OF CHAIDAM PLATE AND ITS EVOLUTION
Yang Huixin Yu Huimin Li Pengwu(Department of Geophysics)
The paper illuminates evolution model of Chaidam plate and adjacent plates on the basis of six palaeomagnetic data from chaidam and combining known palaeomagnetic data. The result indicates that Chaidam plate located close to the dquator and in the low Latitude region from the Sinian peried to the Carboniferous period. Chaidam, Yangtze and Corridor transit zone located all close to the dquator in the Carboniferous period, three plates might be connected together, but palaeolatitude difference is at least 10° or so between North China plate and above-mentioned three plates, for this period, North china was not connected together with Chaidam, Yangtze and Corridor transit zone at that time.
