摘要
Abstract
Northern Shanxi province is considered to be one of the most popular places for the tectonic facies researches due to the various structural characters at different crust levels.In the present study,the relative order of geological events in Early Precambrian was established using the structural analysis combined with the research progress of geological rheology.The results are as follows： the rocks of the lower crust in Datong-Jining areas are believed to consist chiefly of granulite-facies metamorphic rocks;the high grade metamorphosed crustose rocks in Hengshan Mt.may represent the transitional zone of mid-lower crust;the amphibolite facies metamorphic rocks are mainly in the southern areas（Wutai Mt.）;the greenschist facies metamorphic rocks are characterized by the presence of upper crust in Hutuo group.In addition,based on the different geological characters of fold,fracture,pudding of the rock and syntectonic crystallization,we provide some references for analyzing the tectonic facies and the structural phase transition in the Northern Shanxi province.关键词
