In the late Triassic epoch, China is one of the few wide spread and resourceful coal basin countries, but the exploration of most regions is not enough for the development and utilization of coal resources, especially. Stratigraphic sequence and coal are well developed in Shaoshan coal field in the upper Triassic formation which is a primary coal-bearing stratum. Due to the complexity of regional tectonics and coal accumulation, there is not a clear understanding about sedimentary environment and paleogeography in late Triassic. Based on the analysis of outcrop and drilling data in detail, the research work of the paper consist of identification of sedimentary facies type and model of the study area and the drawing of lithofacies palaeogeography maps. The research findings are basis to the exploration and forecast of coal resources in Shaoshan coal field of eastern Hunan.
