Qinghai Province is located in the northern QinghaiTibet Plateau. Due to its special tectonic location， the geological structure and lithofacies palaeogeography are rather complicated. Its lithofacies palaeogeography has been studied for less than in other provinces. To some extent， this became a restricting factor of the exploration work. Based on the new data and research results of the coalbearing strata sections including regional geology， coal exploration and petroleum geology， the authors compiled the lithofacies palaeogeographic maps of Qinghai Province including the Carboniferous， Permian， and Triassic; and discussed the depositional environments. During the Carboniferous， the Qaidam and Qilian palaeolands existed in northern Qinghai Province. From north to south， the Jun UL， Qimantag， Anyemagen and Jinshajing troughs were developed. The Jun UL and Qimantag troughs expanded. The Anyemagen restricted ocean basin， Xijir Ulan restricted ocean basin and Jinshajiang restricted basin were formed. This study provided a foundation for further compilation of lithofacies palaeogeographic maps of the main coal formation periods in Qinghai Province， and has an important practical significance in predicting the areas favorable for coal formation.
