| 摘 要： | 宁镇,茅山山脉褶皱逆冲一推覆构造带的构造岩类型主要为碎裂岩系列,其次为糜棱岩系列。主要超微构造为位错构造。经计算,区内印支、燕山期古差应力值约为90~100MPa,应变速率为:3.1x10~(-14)≤(?)≤2.0x10~(-10)。构造变形环境为低温、高压、高应变速率环境,微观机制主要为位错滑移。

| Abstract: | The main type of tectonites in the belts of fold thrust - nappes in Ningzhen, Maoshan mountains is the cataclasite series, and then mylonite series. The main ultramicrostructures are dislocations. Through calculations, the palaeo-differential stress value in Indo -Sinian and Yanshanian epoch was about 90 ~ 100 MPa, the strain rates were: 3.1 × 10~-14≤ε≤2.0 × 10~-10. The environment of the tectonic deformation was characterized by low temperature, high pressure and high strain rates. The micromechanism was mainly dislocation slipping. |
