白云岩是地质历史中常见的一种碳酸盐岩，但在现代近地表环境下却很难见其踪迹，因此其成因问题成为研究热点。近年来的研究表明，白云石的形成与有机物密不可分。本文在调研大量文献的基础上，从形成白云石动力学障碍这一微观机制出发，探究了其成因。结果表明，微生物的新陈代谢所起的调节作用是白云石形成过程中的关键因素。另外，有机大分子如多糖、羧甲基纤维素、羧基等也能以与硫酸盐还原菌类似的方式促进白云石的形成，这为研究白云石的成因机制提供了新的思路。

Dolomite is commonly found in the ancient carbonate but rarely in the holocene sediments,which forms the fa-mous “dolomite problem”.In recent years,researches had shown that organic matters are inevitable in the formation of dolomite.On the basis of the investigation of a large number of domestic and foreign literature,this paper explored influ-ence factors of dolomite formation from the perspective of the microscopic mechanism of dolomite dynamic obstacles.The results showed that microbial metabolism regulating played a key factor in dolomite formation,for example,sulfide pro-duced by sulfate-reducing bacteria can reduce the energy of magnesium ion dehydration,which accelerates the dissociation of magnesium ion and promotes the precipitation of dolomite.Studies had also shown that organic macromolecules such as polysaccharides,carboxymethyl cellulose,carboxyl-group,can promote the formation of dolomite in the same way of the sulfate reducing bacteria.This provided a new thought for the research of dolomite genetic mechanism.
