The grain size distribution and quartz grain (1.0-0.8 mm) abrasion degree for the contemporary aeolian sands occurring in a zone of taiga and steppe in the neighbourhood of Lake Baikal, in Eastern Siberia, is compared with similar features in other aeolian sediments. Five sites in a taiga zone, one in a forest-steppe zone and one in a steppe zone have been investigated. Whereas the moipho-forming influence of the wind is obvious in the area investigated, the role of the wind is important only in respect of grain size distribution and is not an important factor in detemiining in quartz grain abrasion size.
