Abstract

The main content in this paper is application of fluid-inclusion analysis in dividing formation stages of carbonate cements that formed in fractures belong to Cambrian and Ordovician rocks of West Hills Peking outcrops. The homogenization temperatures of salt\|water inclusions mainly vary from 94 to 98℃ and 133 to 145℃, corresponding to salinities changing from 4 to 8.9%NaCl and 11.9 to 12.5%NaCl. The carbonate cements that formed from 1975 to 2075m and 2950 to 3250m can be divided into two periods of Ⅰand Ⅱ, corresponding to Middle Jurassic Early Cretaceous and Paleogene, respectively. Both of two periods cements formed in the upper part of convection zone.
