| 摘 要： | 通过在野外露头采集定向标本并在室内进行切片研究，对区内主要发育的断裂进行控制，显微构造现象的研究结果反映出本区总体上属于地壳浅层次的低温、低围压和高应变速率的变形环境。根据方解石动力双晶化颗粒百分数对本区进行了古应力大小估算，结果表明，本区古应力值在40～77MPa区间，构造变形强度中等。

| Abstract: | Through sampling of oriented samples in field outcrops then sliced into thin sections and studied them indoor. Controlled main faults developed in the area, the studied results of microstructure phenomena reflected the area belong to a deformational environment of shallow crust low temperature, low confining pressure and high strain rate. According to calcite dynamic twinned particle percentage estimated paleostress scale, the result indicated that the paleostress value in the area should be within 40-77MPa, belongs to medium tectonic deformation intensity. |
