| Abstract: | The main depositional systems identified in No 1 member of Xujiahe formation, which developed in early late-Triassic gulf of NW Sichuan basin, include carbonate platform, bartier island-lagoon, and braid delta, etc. Shallows and sponge bioherms are the main facies of carbonate platform systems. Barrier island-lagoon systems can be subdivided into:barrier beach, storm washover, lagoon, and bayhead delta, etc. Braid delta systems mainly consist of braid river deposits in delta plain facies, rapid accumulation deposits, slump deposits and turbidites in delta front and prodelta facies. Organic geochemical analysis shows that sponge bioherm, lagoon and prodelta facies have good potential of hydrocarbon generation. |
