The uplift of the basement in the eastern Tianshan mountains was mainly completed during the Cretaceous, after which no rapid uplift occurred. The present tectonic framework of the eastern Tianshan mountains basically inherits that of the Mesozoic, but that of the western Tianshan mountains was mainly formed during the Cenozoic intracontinental orogeny. The difference is caused by scissor-like closure of the southern Tianshan oceanic basin starting from west to east and oblique collision of Tarim block with terranes lying toward north during the late Paleozoic.
