摘　　要：本文概述了沉积岩后生蚀变的概念、判断依据、成因及分类 ,着重阐述了氧化蚀变和还原蚀变各亚类的矿物 地球化学标志及其特征 ,分析了后生蚀变与铀矿化的关系 ,指出后生蚀变控矿分带性的两种模式 ,最后简要说明了后生蚀变的研究方法。This paper introduces the concept, the recognition criteria, the genesis and classification of the epigenetic alteration of sedimentary rocks in brief, and expounds the mineral-geochemical indications and characteristics of oxidation and reduction alterations in different geochemical zones in detail, and proposes the two models of ore-controlling zonation of epigenetic alteration. The authors finally introduce research methods of epigenetic alteration.
