碳酸岩占沉积岩体积的五分之一。全世界将近一半的石油、天然气产于其中。许多沉积矿床和热液交代矿床,如铁、锰、磷、镁、铜、铅、锌、汞以及放射性元素等矿床多产于碳酸岩中。碳酸岩本身也是建筑、化工、纺织等工业部门的重要原料,因而碳酸岩的研究愈来愈被重视。碳酸岩的合理分类是研究碳酸岩的必要途径。本文根据我们对燕山震旦系 Carbonatite accounts for one fifth of the volume of sedimentary rocks. Nearly half of the world’s oil and gas are produced. Many sedimentary deposits and hydrothermal metasomatic deposits, such as iron, manganese, phosphorus, magnesium, copper, lead, zinc, mercury and radioactive elements such as deposits prolific in carbonate rocks. Carbonate rock itself is also an important raw material in the construction, chemical, textile and other industrial sectors. Therefore, the research of carbonate rock is paid more and more attention. The reasonable classification of carbonates is a necessary way to study carbonatites. This article based on our Yanshanian Sinian
