摘要
The recognition of carbonate origin in lake facies of the second member of Funing Formation, the west slope of Jinhu Sag existed different viewpoints, so the major part of this research was the sedimentary facies of the carbonate rock. After the analysis of the components of carbonate rock, the conservation of fossil, the distributed law of the stratum thickness and cryptite, the facies can be classified into carbonate sheet, carbonate dam, and carbonate strand and corcass. Finally, the sedimentary model of the carbonate rock in lake facies was established.
