| Tectonic Features of Metamorphic Core Complexes in Yiwulushan Area, Liaoning Province and a Dynamic Analysis of Rock Fabrics |
| We divide structural elements of the metamorphic core complexes in the Yiwulushan into five parts,namely,the metamorphic core complexes, the fault, the middle passage bed, the cover rock, and the Yiwulushan antiform, with a description given concerning geological features of the metamorphic core complexes. Rock fabric studies were carried out by means of X-ray diffraction method on layered deformation structures of rocks of different ages in Yiwulushan Mountain area. Mechanical properties and major stress orientations in the process of ductifle-brittle deformation were determined. A kinetic and dynamic analysis was also made on the formation and evolution of the deformation structures in the metamorphic core complexe of the Yiwulushan Mountain. |
