通过详细测制西藏改则地区上三叠统日干配错组(T3r)剖面，取得认识有：在沉积学方面，通过对实测剖面的岩性、沉积构造分析，将日干配错组第一段划分为半深海陆棚相到碳酸盐台地相，日干配错组第二段划分为滨浅海碳酸盐台地相，并从中划分出浅滩亚相和浅水缓坡亚相，通过地层对比和化石资料，提出日干配错组时代属晚三叠世；控盆机制方面，在晚三叠世，研究区的应力背景与班公湖-怒江洋盆的打开同步，盆地以张扭性为主。

By measuring profiles of the Upper Triassic Riganpeicuo Formation in Gaize,Tibet ,the main conclusions and results are summarized as following:On the sedimentological aspects:with the lithology,sedimentary structure analysis,the first member of the Rigain Peicuo Formation is divided into bathyal shelf facies to carbonate platform facies; the second member of the Rigain Peicuo Formation is divided into infraneritic carbonate platform facies, which is divided intoshoal subfacies and shallow gentle slope subfacies.By contrasting with stratum and fossils, the period of Rigain Peicuo Formation is Later Triassic.On the basin-controlling mechanism aspects:Later Triassic, the stress of the study aera has synchronous to the opening of the Bangong Co-Nujiang ocean basin and the basin mainly is tenso-shear structural.
