Grain Size and Sedimentary Sorting Characteristics of Atmospheric Dust in the Cele Oasis, Southern Margin of Taklimakan Desert

Grain size is a proxy indicator of airflow intensity and also provides scientific basis for the prevention dust hazards. However, variations in grain characteristics that occur during transport deposition processes are seldom discussed. Here, atmospheric samples were collected before after sand–dust storm analysis. The results showed distributions unimodal transportation but always became bimodal deposition. This indicates distribution aeolian deposits was caused by sedimentary sorting. coarse-grained component, which between 20 200 ?m, mainly deposited storm. may indicate strength field. fine-grained ranged from 0.4 to component can remain suspended atmosphere long period time. Oasis shelterbelts be used reduce aerosol through interception particles foliage. variation found this study deepens our understanding sediment sorting process.
