On the basis of his prolonged field works and ample literature the author discusses Pre-Quaternary and Quaternary evolution of the relief and main tectonic structures within the region, which is almost unknown to the Soviet reader. Geomorphological evidences are given for the planation surfaces having been formed at high levels and age of the surf aces is speculated, a sequence of upwarping and thrust-sheet structures formation is established, as well as alternation of tectonic activity and relative quiescence, rate and amplitudes of vertical and horizontal displacements are determined. Main topographic characteristics and stages of evolution of the region-are compared with those of adjacent regions (the Himalaya, Pamir and Tibet).
