Mantle plume can form kilometer-scale lithospheric doming uplift and make a notable impacts on paleogeographical pattern.According to the Emeishan Large Igneous Province & mantle plume researches informations ,as well as outcrops and drilling data of Qixia Fm. in Sichuan basin, the paleogeographical pattern and sedimentary facies distribution on the spatial and temporal consequences,which were controlled by mantle plume uplift, has been evaluated in this region. The doming uplift formed by Emeishan mantle plume controlled the paleogeomorphology and further influenced the sedimentary facies distribution.During the Qixia period of the middle Permian, the higher part of the doming uplift is in the SW area of the Upper Yangzi plateform,and towards the east and northeast,the slope of doming uplift gradually goes down geographically. The gradient break and escarpment were not development on the slope. This kinds of paleogeographical pattern with local sea level change controlled the Qixia period sedimentary facies distribution and strata thickness,and formed carbonate ramp platform model. According to the lithological correlation and sedimentary structures on different places of the doming uplift,the open platform subfacies,shallow ramp subfacies and deep ramp subfacies could be recognized. The open platform is located on the higher part of the doming uplift which is in the SW area of the Upper Yangzi plateform, the ramp area developed on the slope of the doming uplift which towards the east and northeast parts of the Upper Yangzi plateform. The paleogeographical pattern and sedimentary facies distribution of this area could be believed as the early developed stage from carbonat ramp to platform，and the evidences of the Emeishan mantle plume movement.
