FORMATION STAGES OF STEPPE LANDSCAPES IN EURASIA. QUATERNARY
Abstract
The article dwells on the formation of ancient steppe flora, which took place at the final stage, in the Quaternary (1.5—2 mln. years ago), due to sharp cooling of the climate which led to mass extinction of thermophilic flora, the expansion of the steppes, including within southern mountainous areas. Both in the plains and in the mountain steppes changed their shape and floristic composition. For example, Pamir (southern Central Asia) experienced changes in types of mountain belts.
Key words
