Mar 2, 2023 · Two lithofacies assemblages are identified in the Chang 7 Member. The assemblage composed of clayey shale, laminated silty shale, quasi-laminated silty shale, and laminated argillaceous siltstone lithofacies mainly occurs in the deep-water sedimentary environment of the semi-deep–deep lake facies in the lower Chang 7 Member. Most of the silt-sized fraction is quartz, but very little of the clay sized fraction is quartz.
