白云石形成作用减弱的原因之一是有利于白云石形成的浅水地台海面积减少和白云石形成转移到沿岸地带。对碳酸盐聚积作用产生影响的因素是:①气候因素;②构造因素(岩石圈板块的坳陷速度和位置决定有利气候条件下陆棚的存在);③全球海平面的变化(影响陆棚的深度和面积)等。这些因素之间的关系复杂,并且对碳酸盐聚积的影响各不相同,因此,实际上弄不清哪一个是主要因素。古生代和中—新生代,由于气候环境与海平面变化的关系、大气圈气体成分等碳酸盐的聚积与白云石的形成也各不相同。
One of the reasons for the weakened dolomite formation is that the shallow oceanic platform area, which contributes to dolomite formation, decreases and the dolomite formation shifts to the littoral zone. The factors that affect the carbonate accumulation are: ① climate factors; ② structural factors (the speed and location of lithospheric plate depression determine the existence of continental shelf under favorable climatic conditions); ③ global sea level changes The depth and area) and so on. The relationship between these factors is complex and has a different impact on the accumulation of carbonate so it is practically not clear which one is the main factor. Paleozoic and Meso-Cenozoic, due to the relationship between climate and sea level changes, the accumulation of carbonates such as gas components in the atmosphere and the formation of dolomites also vary.
