Description :
In this paper, 33 representative surface sediment samples were collected from the Kumtagh Desert and analyzed in the laboratory to obtain heavy mineral components and geochemical element contents. Results show that various kinds of heavy minerals are present in these samples, with high levels of epidote and hornblende. The AA. investigate the source region of these sediments. They also evaluate the effect of physical weathering process on the mineralogical and geochemical composition of the desert sands.
