NAPPE STRUCTURE IN MOUNT SEERTENG, INNER MONGOLIA
-
摘要: 基于1∶5万地质调查资料和野外重点地区的解剖研究, 结合深部地球物理资料, 阐述了色尔腾地区逆冲推覆构造的特征, 详细探讨了本区推覆构造的动力学机制, 认为色尔腾山总体为一巨型推覆体, 且造成本区大规模逆冲推覆的主要动力是局部应力场的作用——相向地幔环流体系的隆升.Abstract: The thrust nappe structural features in the Mount Seerteng are presented in this paper on the basis of the information on the regional geological investigation (1∶50 000), the field work in target areas and the geophysical references on the depth of the earth. Moreover, the detailed analysis of the dynamic mechanism of the nappe structure in this region indicates that the Mount Seerteng is a massive nappe body, and that the major dynamic force for the presence of the large-scale thrust nappe in this region is the action of the local stress field — the elevation of the mantle current system circulating in the opposite directions.
