According to the lithology and geochemistry analyses, the Permian and Triassic dolostones in Northeastern Sichuan Province can be classified into three types: reef dolostone, grain dolostone and gypsum-bearing muddy dolomicrite. The reef dolostone is formed in mixed water which is mainly controlled by frequent change of the sea level. Grain dolostone is formed in the deep burial dolomitic environment by mixing-water dolomitization. Penecontemporaneous or seepage-reflux dolomitization is the original mechanism for gypsum-bearing muddy dolomicrite.
