摘　　要：碳酸盐岩孔隙演化受各种成岩作用的控制，其中胶结作用对孔隙演化起了重要的作用。利用地球化学分析手段，对川东石炭系碳酸盐岩胶结物进行了研究，碳酸盐岩中存在白云岩粒间胶结和石灰岩粒间胶结两种胶结物，不同成岩时期及成岩环境形成的胶结物的地球化学特征差异显著。川东石炭系埋藏成岩作用过程中，埋藏胶结物对孔隙演化有一定的影响。利用地球化学手段定量地描述胶结作用。Carbonate porosity is mostly controlled by diverse diagenesis, especially by cementation. The processes of age\|cementation can express porosity evolution history. This paper discussed burial diagenesis and cementation in the carbonate rock of Carboniferous period in the east of Sichuan province with chemical analysis. There are two types of cemeltations in carbonate rock in this area. The geochemical characteristics of these cementations formed under different diagenetic stages and diagenetic environments are various. The burial cementation has some influence on carbonate porosity evolution. The chemical analysis of cementation can provide the theoretical basis of favourable exploration.\=
