黔桂地区泥盆、石炭系层状白云岩，厚度大，层位稳定，主要分布于与陆相连的碳酸盐岩台地外缘及孤立碳酸盐岩台地上。研究认为，白云岩的形成模式主要有５种，即潮汐泵汲白云石化模式、正常海水白云石化模式、近地表混合（水）白云石化模式（可分为海水较高和海水较低二种模式）、埋藏成岩环境白云石化模式（又可分为压实排挤流和热（盐）水为主混合的二种模式）及构造热液白云石化模式。不同的白云石化模式具有各不相同的机理和特点
Devonian and Carboniferous stratiform dolomites in Guizhou and Guangxi are of great thicknesses and stable layers. They are mainly distributed on the outer margin of carbonate platforms connected to the continent and on isolated carbonate platforms. According to the study, there are mainly five types of dolomite formation patterns, that is, tide pump model of dolomitization, normal seawater dolomitization mode and near-surface mixing (water) dolomitization mode (which can be divided into two modes: higher seawater and lower seawater ), Burial diagenetic environment dolomitization model (again can be divided into compaction of the squeezing flow and heat (salt water) mainly composed of two kinds of patterns) and tectonic hydrothermal dolomitization mode. Different dolomitization patterns have different mechanisms and characteristics
