HILLOCKS OF SOUTH-WEST TURKMENIA AND THEIR CORRELATIVES

Abstract

On the coastal and especially piedmont plains of South-West Turkmenia, specific near-bush consolidated hillocks (tommocks) are widespread, the origin of which depends on eolian processes. In nature the eolian formations correlative with the hillocks-tommocks are rather numerous, beginning with small near-bush hillocks and up to big eolian constructions forming under analogous conditions of a wind flow in the shadow of uplands («shadow dunes») or in the regions of travelling sands (Baer knolls). Wind is the main agent under the influence of which the material for these formations ns accumulating, but the emergence of a concrete variety of these forms is determined by the regime of winds, the level of ground-water, as well as by the properties of plants or other obstacles which create the wind shadow.
