| 摘 要： | 识别胶结作用、交代溶蚀作用、沸腾作用等三种成岩作用，以及有机质填隙、破裂等改造作用。总结出以胶结作用为主的成岩演化序列。铅、硫同位素研究认为从全岩到胶结物，铅同位素发生了质量迁移和分馏作用；硫主要来源于地层有机质或湖相硫酸盐中的还原硫。

| Abstract: | According to the identification of 3 types of diagenetic processes,ie,cementation,metasomatic corrosion,boiling,the reformation processes of fissure filling of organism and fragmentation,the diagenetic evolution series(the cementation is the main process of it) has been summarized.The Pb,S isotopic study shows that the mass migration and the fractional distillation of Pb isotope took place in the whole rock and in the cement.The S is mainly resulted from the reduction S in stratigraphic organism or lacustrine sulphate. |
