Topographic levels in isolated sand massives at SW Turkmenistan

Abstract

Five topographic levels (steps) are distinguished in the sand massives at SW Turkmenistan. The levels height corresponds the coastlines of early and late Khvalynian seas, the author considers them to be Khvalynian terraces reworked by wind after the sea regression. Searches for oil and gas should take into account the presence of the Khvalynian topographic levels of different age.
