| Abstract: | Fluid inclusions are the samples of thermal fluid in structrue events and are preserved in a great quantity within fault rocks. Various associations of fluid inclusions are present in the distinct faults with different property in different depth. In extensional fault, there are a lot of fluid inclusions with bigger size of grains and wider range ratio of vapor to liquid. The boiling group of inclusions often came out. In compresional fault, fluid inclusions have smaller size of grains and arrange in fixed directions in ductile shear zone , fluid inclusions rarely occur. Their temperature of homogenization is higher. The melt inclusions and pure CO 2 ones appear at deeper level. |
