摘要：

Samples of dust deposits were periodically collected from July 1, 1997 to January 30, 1999, at Souss-Massa basin, in the South of Morocco. Granulometrical, geochcmical and mineralogical characterisations show that quartz, calcite and feldspars dominate the mineral contents of the dust deposit with a minor clay fraction. It indicates the mineralogical composition of dust collected in peri-Saharan regions. The material collected in the summer period is dominated by local dust against a mixture of local and proximal dusts in the winter period. (C) 2004 Published by Elsevier Ltd.
