ARID GEOMORPHOLOGY IN THE WORKS OF HERMAN NIKOLAYEVICH PSHENIN

Abstract

G.N. Phenin ascertained that the range of the Fergana Basin downwarping during the N-Q stage amounts to 2000–3000 m, and not to 6000–7000 m as had been previously assumed. He also suggested an expansion of the Central Asia mountain systems to be but a particular case of a general regularity; the latter consists in that stages of greater differentiated tectonic activity in particular morphostructural zones (e.g. axial, frontal, medium-high and low mountains) alternate with stages of general uplift or subsidence of the entire mountain system.
