| 中文摘要:本文将云蒙山地区挤压伸展体系的构造要素划分为：①四合堂推覆体；②大水峪韧性剪切带；③云蒙山背形构造；④崎峰茶滑脱带；⑤河防口低角正断层；并简述了它们的地质特征。采用X射线衍射法对云蒙山花岗岩及周围不同时代岩石的不同层次变形构造开展了岩石组构特征研究，确定了韧脆性构造变形时的力学性质和主应力方位，对挤压伸展体系变形构造的形成演化进行了运动学和动力学分析。 |

| Abstract:This paper divided structural elements of the compressional and extensional system in the Yunmenshan Mountain into five parts, namely the Sihetang nappe, the Dashuiyu ductile shear zone,the Yunmengshan antiform, the Qifengcha deachment zone and the Hefangkou low angle normal fault, and gave a description of geological features of this compressional and extensional system. Rock fabric studies were carried out by X ray diffraction method for layered deformation structures of rocks of different ages in Yunmengshan mountain area. Mechanical properties and major stress orientations during the ductifle brittle deformation were determined. Kinematic and dynamic analysis on the formation and evolution of the deformation structures in the compressional and extensional system of the Yunmengshan Mountain was also made. |
