Abstract: Based on boreholes and stratigraphic sections, we draw maps about uniformly thick residual formation in the Longmen Shan Foreland Basin with Surfer 8.0 software, work out the total amount of sediment of residual formation, and figure out the sediment flux in each phase: 21.4t/(m2·Ma),184.2t/(m2·Ma),278.0t/(m2·Ma), 147.6t/(m2·Ma),703.5t/(m2·Ma), and 272.0t/(m2·Ma). Then we denude back the sediment to the orogenic belt based on material balance method and carry out depressure correction. We can work out the aggregate thickness denuded is about 2 514 m on Longmen Shan during the late Triassic Epoch, and the speeds of denudation in each phase are: 0.009 mm/a,0.114 mm/a,0.13
