内蒙古色尔腾山──大青山地区推覆构造

内蒙古包尔腾山──大青山地区推覆构造，随着1∶5万区域地质调查工作的开展，在原来发现的几个孤立的推覆构造的基础上，相继识别出一些新的推覆构造，从而使我们有可能纵观本区推覆构造的全貌。它们呈近东西向展布，主要发生在东西向侏罗纪成煤盆地的南北两侧，前中生代地层及侵入体做为外来系统逆冲推覆在中生代盆地之上，并发育大小不等的飞来峰、构造窗。它们形成于中侏罗世末和早白垩世末，是在南北向水平挤压的统一的构造应力场中发生发展的。推覆构造研究，对认识本区地质构造的演化和地壳的层圈式结构将是十分有益的，对指导找矿也有一定的意义。

Nappe Tectonics in Sertengshan-Daqingshan, Inner Mongolia

Along with 1: 50000 of regional geological surveying has developed that the base of a few isolated nappe tectonics had been discovered in the original to distinguish some news,in this way we can look on the whole area of the nappe tectonics spreaded out the eastwest trend that mainly took place in the east-west trend of Jurassic formed coal basin of south-north two limbs and the Premesozoic stratum which has been developed some different size klippes and windows and intrusive bodies made outside system to obduct and nappe on Mesozoic basin. They have taken place and developed in the south-north tread of the horizontal compressed of united structure stress field and have formed at late of middle Jurassic and eatly Crelaceous. The nappe tectonics study that has great significance to guide the prospecting deposits and is very usrful to recognize this area geological structure of envirnment and the layer-round or texture.
