| 摘 要： | 内蒙古大青山地区侏罗纪盆地中发育有断层相关褶皱，有十分清晰的断层传播褶皱，断层转折褶皱等构造样式。断层相关褶皱轴向呈东西向展布，形成褶皱的地层是早侏罗世右拐群煤系地层，表明该褶皱至少在煤层形成后，受南北向挤压应力作用形成。研究这一构造样式，对这一地区的推覆构造、盆山耦合研究具有重要地质意义。

| Abstract: | Widely distributed in Daqingshan area,Inner Mogolia,nappe structre and extensional structure constitute the west section of Yansan mid plate orogenic belt,an important formation part in Yinshan Mountain.Those fault related folds are distrbuted including faulted propagated fold and faulted hinged fold are distributed in Jurassic basin of Daqingshan Mountain.The fault related folds with a axial direction of east west form fold strata of coal measures strata in Lower Jurassic Shiguai Formation.The folds are formed at least by stress of compression at south north direction after formation of the coal seam.The research on the structural style is of important significance for the nappe structure,coupled basin range and coalfield exploration in the area. |
