Abstract

The AA. investigated dust fallout characteristics at a height of 3 m and rare earth element (REE) geochemistry of different landforms in the Taklamakan sand sea, which has frequent dust events. The seasonal fallout and concentrations of PM10 particles and monitoring results of their land surface concentrations show that the Taklamakan sand sea is surrounded by dust sources, and it's an important dust deposit area. The particle size characteristics of dust sediment suggest that the dust-conveying capacity of the Taklamakan sand sea is much stronger than that of the Gobi and degraded surfaces on the sand sea edge. It is highlighted that the areas surrounding Taklamakan sand sea are the main dust source areas. Taklamakan sand sea is also an important source of reworked dust
