    MIDDLE PROTEROZOIC TECTONIC DEFORMATION AND EVOLUTION OF THE LANGSHAN-ZHARTAI MOUNTAINS IN INNER MONGOLIA

    • 摘要: 内蒙古狼山—渣尔泰山地区,在中元古代形成了相似的沉积岩石组合,分别称为狼山群和渣尔泰群,本文对其褶皱、构造、变形与演化进行了分析。

       

      Abstract: The Langshan and Zhartai Groups of extensional transitional crust nature formed on the basis of the Changchengian(Middle Proterozoic)taphrogeny at the northern margin of the North China platform underwent solid rheologic folding and bedding ductile shear sliding at the early stage,folding-thrusting in the main stage and superimposition and reworking in the late stage in the middle-late Proterozoic folding and orogeny,thus giving rise to the Langshan normal fan-shaped nappe structure and the isoclinal folding-frac- turing structure.By using voluminous statistical data obtained by field sur- eying,this paper deals with the features of tectonic deformation of various vstages and then discusses the sequence of tectonic evolution of the middle and late Proterozoic fold belt in the Langshan-Zhartai Mountains at the northern margin of the North China platform.
