Through the analysis of clay minerals, major and trace elements of the Carboniferous mudstone samples collected from cores in Bachu, Tazhong and Tahe areas and field outcrops around Xiaohaizi in Bachu and Sishichang in Akesu, palaeosalinity character of water environment was revealed by quantitative semiquantitative analysis. The results indicate the range of palaeosalnity is 4.7‰～33.9‰, and display that the majority of mudstone samples show semi-saltwater sedimentary environment and freshwater-brackish environment is secondary while saltwater environment is less.
