摘　　要：Objective The Yanyuan and Sichuan Basins,located at the southwestern margin of the Yangtze Block,are separated by the Kangdian Oldland.The provenance of the Upper Triassic sediments deposited in the Sichuan Basin has been extensively studied much based on detrital zircon UPb geochronology(Zhang et al,2016;Zhu et al.,2017;Yan et al.2019).
