碳酸盐岩沉积环境的分析及岩相古地理的研究是碳酸盐岩石学的一个十分重要的内容。在勘探与碳酸盐岩有关的矿产时,都要对它的岩性、岩相作详细的观察和分析,探讨其沉积环境,并揭示其和矿产形成、分布和富集的内在联系。近二十年来,对沉积模 The analysis of carbonate sedimentary environment and the study of lithofacies palaeogeography are very important contents of carbonate petrology. In the exploration of carbonate-related minerals, its lithology and lithofacies should be observed and analyzed in detail, the sedimentary environment should be explored, and the intrinsic relationship with the formation, distribution and enrichment of minerals should be revealed. Nearly two decades, the deposition mode
