COMPOSITION OF SAND STORM PARTICLES IN THE SOUTHERN FAR EAST

Abstract

Lithostructural composition of the dust storm material (DMS) sampled in the southern Far East in the spring of 2002-2004 has been analyzed. Samples were taken near Vladivostok, where the eolian dust precipitation varied from 0.1 to 6.5 g/m2 at that time. Pelitic and fine-silt particles predominate in eolian dust. Grain size, mineral, and chemical compositions of the DSM are compared to data on the DSM in adjacent territories of China, Korea, and Japan, as well as to background data on aerosol precipitation in southern Primorye. Possible mechanisms of the eolian dust transport from inner parts of Asia at different climatic variations in the Pleistocene-Holocene are discussed. © Pleiades Publishing, Inc. 2006.
