MIDDLE-LATE CARBONIFEROUS SEDIMENTARY FACIES AND MODEL IN THE SOUTH OF CHINA

Upper-Middle Carboniferous Series in the south of China is mainly carbonate with its extensive distribution, large thickness and various types of facies.Its main feature is that the carbonate platform facies develops well.Duriag this period, a shallow sea with basically normal salinity had been existing in this area, and the relief of the sea bottom was less distinct; thus, the circulation of water was unb- locked. However, there were still some basins with relatively deep water and quiet banks with shallow water within the platform.
