本文从生物地质学观点出发,采用岩石薄片鉴定、电子扫描、光谱元素分析及藻菌分离试验等方法,对我国南方各地区碳酸盐岩中的豆粒、鲕粒、团粒、球粒、粪粒、内碎屑、灰泥、栉壳结构方解石及原生白云岩分析鉴定,并进而对藻菌的生境与生物化学作用进行讨论,认为生物化学作用是形成原生碳酸盐岩的内在主导因素,提出了碳酸盐岩的系统分类及原生碳酸盐岩的岩石分类命名法则,并指出分类对沉积环境分析及研究石油生、储、盖层的重要意义。
In this paper, from the point of view of biogeology, rock tablets, oolong grains, pellets, pellets, fecal pellets of carbonate rocks in various areas of southern China were identified by means of identification of thin slices of rock, electronic scanning, spectral elemental analysis and isolation of algae. , Internal debris, stucco, gut-shell calcite and primary dolomite, and discussed the habitat and biochemistry of algae. It is concluded that biochemistry is the inherent dominant factor in the formation of native carbonate rocks The systematic classification of carbonate rocks and the rock classification nomenclature for primary carbonate rocks are also pointed out. The importance of classification for the analysis of sedimentary environment and the study of petroleum production, reservoir and caprock are also pointed out.
