Special features of recent tectonics at the zone of the Pamir and Tien Shan structures contact

Abstract

On the basis of repeated leveling data processing and analysis two zones- Gissarskaya and Petrovskaya-have been distinguished within Garm geodynamic polygon, which is situated in the zone of Pamir and Tien Shan structural contact. The zones differ in recent tectonics character. The Gissarskaya zone coincides with the Foremost zone of the S6uth Tien Shan, the Petrovskaya one-with the Outer Pamir-Kunlun zone, their boundary being at the Vakhsh up thrust line. Recent structures evolution is inherited from Late and Middle Pleistocene erogenous structures. The whole area of the Garm polygon rises now the rates of the recent rise being lower at the Foremost zone of the South Tien Shan as compared with Outer Pamir — Kunlun zone.
