一、进展与现状 碳酸盐岩的岩相古地理研究是碳酸盐岩石学的核心内容,它与石油、天然气以及其它沉积矿产的勘探和开发有极为密切的关系。 把碳酸盐岩的主要沉积环境浅海,划分为两种性质大不相同的陆表海和陆缘海的是伊迪和肖。古代碳酸盐岩大都是在陆表海中形成的,而现代我们所看到的浅海却大都是陆缘海,因此,在用现代碳酸盐沉积物的沉积环境去推论古代碳酸盐岩的古沉积环境时,就应格外谨慎。欧文进一步提出陆表海清水沉积作用的概念,并用沉积环境中的水动力能量划分出三个能量带,从而奠定了碳酸
I. Progress and Status The lithofacies palaeogeography of carbonate rocks is the core of carbonate petrology. It is closely related to the exploration and development of petroleum, natural gas and other sedimentary minerals. It is Eddie and Shaw that divide the shallow sea, which is the main sedimentary environment of carbonate rocks, into two types of land surface sea and continental margins which are quite different in nature. Most of the ancient carbonate rocks were formed in the land surface sea, while the shallow sea we have seen in modern times is mostly continental marginal sea. Therefore, in the depositional environment of modern carbonate sediments, it is deduced that ancient carbonate rocks Ancient sedimentary environment, it should be extra careful. Owen further proposed the concept of land surface seawater sedimentation and divided the three energy bands with hydrodynamic energy in sedimentary environment,
