摘要

     Based on fieldwork and the study of petrology, three 3 sandrock samples from Middle Triassic in Youjiang Basin were analyzed with LA-ICP-MS U-Pb isotope dating. The results show that the ages of eight groups of crust or recycling crust components are 1100, 950, 850, 750, 440, 360, 300 and 260 Ma, respectively. Compared with former data, statistics results of aging data in this study indicate that the provenance of Triassic sandstone from Youjiang Basin may belong to the Yangtze block, the Cathaysia block and N Viet Nam Old Land.
