摘要
本文对本区四组断裂带脆韧性构造岩中矿物流体包裹体进行了研究。根据赋存包裹体的显徽构造特征,确定了构造岩的应力性质,划分出岩石变形的构造阶段。由流体包裹休及其主矿物的测定,计算出各构造阶段的热动力学条件。最后,指出本区构造演化规律并探索地震活动的特点。
This paper Is concernedwith fluid inclusions in minerals of brittle-ductile tectonites from four fracture zones in Shanghai and its adjacent areas,According to the microstructural featuresof thefluid inclusions,we have determined the strain nature of the tectonites.On this basis,the def-ormational stages of the rocks are distinguished.From the measurements of fluid inclusions and host minerals we have calculated the thermodynamical and kinetic conditions in each of the tectonic stages.The law of tectonic evolution and the characteristics of seismic activity are also discussed.
