Well logs,  outcrops and the principles of the sequence stratigraphy   have  been used to reconstruct sequence stratigraphic framework and to predict the coal distribution of the Upper Triassic coal measures in the Baoding Basin of western Yangtze platform(Sichuan Province). A total of 12 sequence boundaries and 11 fourthorder sequences have been identified in the succession above the No40 coal seam within the Daqiaodi Formation. With the evolution of the basin from a  faulting basin to a largescaled depressional basin，the rate of basin subsidence，thus the rate of new accommodation creation，was slowing down gradually and the coal accumulation had a tendency of strengthening first and then weakening. During the  early stage of the faulting basin，the coal accumulation was less evident and was restricted in a limited area. During the intermediate stage of the faulting basin(sequences Ⅳ-Ⅷ)，coal seams were mainly formed in the LST，near the initial transgressive surface，and in the midlate HST. The coal accumulation center was mostly located in the delta plain setting where a moderate rate of new accommodation creation was maintained. During the late stage of the faulting basin(sequences Ⅸ-XI)，the main coal seams were located in the late TST and early HST，both close to the maximum flooding surface. The coal accumulation center migrated to the depositional center of the basin where the  highest rate of new accommodation creation was kept.
