| Tectonic Features of the Compressional-Extensional System and Dynamic Analysis of Rock Fabric in Yunmengshan Area, Beijing |
| 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. |
