摘要：The grain size dislribution and quartz grain (1.0-0.8 mm) abrasion degree for the contemporary aeolillnsands occurring in a zone oflaiga and steppe in the neighbourhood of Lake Baileal, in Eastern Siberia, is comparedwith similar features in other aeolian sediments. Five sites in a taiga zone, one in a forest-steppe lone and one in asteppe zooe: have been investigated. Whereas the morpho-fonning influence: of the wind is obvious in lIle areainvestigated, the role of the wind is important only in respect of grain size distribution and is not an imponantfoctor in determining in quanz grain abrasion size.
