【Abstract】 In this paper, compositions of mineral and chemistry of sands in the Taklamakan Desert were compared in wide range. The chemical composition of amphibles, oxygen isotope composition and surface texture of quartz in sands from certian of typical regions were discussed. Based on these facts, a research for sand source of some districts was made with referring to geological- geographical conditions in the desert.更多还原
