摘要

By using sedimentology, paleontology and sequence stratigraphy, rock particle size analysis and other methods, the detailed sedimentary characteristics of Tongziyan Formation in Longyong coalfield has been studied in the aspectes of lithology, sedimentary structures, depositional system. The results showed that the Tongziyan Formation is mainly composed of fine-grained lithic quartz sandstones and quartz sandstones with different types of beddings. The evolution of the sedimentary environments of Tongziyan Formation can be divided into three phases: early, middle and late periods.
