摘要
The Jialingjiang Formation of Lower Triassic in Sichuan Basin is composed of carbonate platform sedimentary system and carbonate-terrigenous clastic sedimentary system,and including four major sedimentary facies such as carbonate-terrigenous clastic tidal, restricted platform,open platform and evaporite platform.In the end of Feixianguan stage of Early Triassic, there was a large-scale regression and regional exposure and erosion in the Upper Yangtze maritime space, and until early Jialingjiang stage the Upper Yangtze maritime space underwent extensive transgression and accepted the deposition again. herefore, at the bottom of Jialingjiang Formation of Lower Triassic developed partial exposure unconformity surface and inner of the Jialingjiang Formation mainly developed lithology-lithofacies transformational sequence interface.
