Abstract

Age determination of the Tien Shan is critically revised and a conclusion is drawn on mostly Late Pliocene age of the mountains, Maximum value of neotectonic uplifts at Ghissar Alai is 5 to 6 kilometres, and this of Chatkal-Kuramin Mountains is 4 to 5 kilometres. Out of these values 3,5 to 4 km and 2,5 to 3 km, fall respectively on the Late Pliocene, including late Akchagylian up to 1 to 1,5 km early Apsheronian 1,5 to 1,7 km and late Apsheronian 1,0 to 1,5 km. Formation of the present topography at Pamir-Alai place earlier as compared with the Chatkal-Nurata region topography (Akchagyl Apsheron in the first case and Apsheron Pleistocene in the second). The difference of the relief age may be used as one of basic principles of morphotectonic subdivision of the area. (L'Ed.).
