| 摘 要： | 茅山顶宫地区的流体包裹体迹面分析结果表明,该地区中生代以来的构造经历过多期构造演化,主应力方位表现出由北西→北北西→近北→北西→北东→西北西方向的变化,并以北西方向为主;主应力性质由压扭→张性→压扭→张性呈多期改变.这些事件依次对应于茅山中生代以来第一次北西向推覆构造、K2茅东张裂盆地,以及新生代挤压、拉张交替演化过程.茅山断裂构造期温度显示出由高到低的变化特点,相应地压力也由大到小变化.

| Abstract: | Fluid inclusion plane (FIP) analysis carried out in Dinggong area,Maoshan shows that the studied area experienced multiple stages of tectonic evolution since Mesozoic. The orientation of the principal stress changes consecutively from NW to NNW to N to NW to NE to WNW. Accordingly, the stress field shifts between transpression and extension. These changes are related to the regional tectonic events in the region such as thrust and extensional tectonics. FIP study also demonstrates that both the formation temperature and the pressure of the inclusions have decreased since Mesozoic. |
