Thus, dust records of ac- cumulated aeolian dust deposits (red clay and loess deposits; dust samples of deep-sea sediments; terrestrial material in ice-cores) are of significant importance in reconstructing past climatic and environmental processes, circula- tion patt erns, dust source areas and emissions (Pye, K. 1987, 1995;	cache/hungeobull-3015.pdf	txt/hungeobull-3015.txt
