Morphostructure and recent tectonics at the lower reaches of the Obikhingow River (near the Garm test site, Tadjikistan)

Abstract

Repeated levelling of high precision was carried out in 1948 to 1975 along the Garm geodynamical test site profile (right bank of the Obikhingow River) 35 km long. The profile runs across two large morphostructures, such as Sukhob-Vakhsh intermontane trough and erogenous uplift of the Peter the 1st Ridge. The Holocene tectonic movements of the morphostructures are estimated on the basis of the young fluvial terraces distortions, Geodetic data (usually of relative character) on the recent tectonic movements rates indicate mostly tendencies of the block morphostructures evolution during the Late Holocene.
