Abstract
The mineralogy and mixing state were investigated by the high resolution scanning electron microscopy combined with energy-dispersive X-ray analysis on particles of the total suspended solid (TSP) samples collected during the Asian dust event, spring, 2009. Relatively large particles were dominated by quartz, plagioclase, K-feldspar, amphibole, biotite, muscovite, chlorite, and calcite. Clay minerals usually occur as thin coatings on the coarse minerals or as aggregates. Calcite nanofibers are often admixed with clay platelets in the clay coatings and aggregates. Dust particles were classified on the basis of their main minerals. The single-particle mineralogy and mixing state of the TSP sample are consistent with those of $PM_{10}$ samples in previous studies.
