The diagenesis of detrital rock includes compaction and pressure solution, cementation and consolidation, recrystallization,metasomatism,the formation of endogenic minerals, etc The diagenesis of argillite rock consists of compaction and the inversion of clay minerals Their diagenetic process may be divided into four stages of syngenesis,lithogenesis,epigenesis and supergenesis Therefore,there are different rock types with varying diagenetic features occurring at the evolving stages and diverse locations of a depositional basin

中国南方震旦纪碎屑岩的成岩作用主要有压实和压溶、胶结和固结、重结晶、交代作用及自生矿物形成等，泥质岩的成岩作用主要为压实作用和成岩过程中粘土矿物的转化。 其成岩过程可分为同生、成岩、后生、表生四个成岩作用阶段。
