摘要
所谓成岩相是指具有特征的成岩组构的岩体。研究成岩相的目的主要是通过对沉积物中不稳定颗粒在不同的成岩条件下的后生变化特征的研究来弄清其成岩环境的变化。本文通过对湖南慈利晚二叠世生物礁成岩特征的研究,从礁相体系中划分出四种基本的成岩相类型:即海底成岩相、混合成岩相、埋藏成岩相和表生成岩相。部分成岩相又可进一步划分出成岩亚相。
Diagenetic factes refers to a rock body which is characteristic of diagenetic fabric. The main purpose of diagenetic factes study is to make it clear the evolution of diagenetic envirenment by studying epigenetic diversion of unstable particles in deposition under different diagenetic conditions. In this paper, four basic types of diagenetic factes were identified in the reef factes system by studying diagenetic characters of the Late Permian reef in Cili, Hunan Province. They were the sea floor diagenetic factes, fresh-saline water diagenetic factes, deep-buried diagenetic factes and fresh-water diagenetic factes. Some of the factes can be subdivided further
