| Abstract: | Western Tianshan orogenic belt of Xinjiang is in the central and southern part of ancient Asian tectonic region where magmatic activities were very intense in the Paleozoic and intrusive rocks extensively developed.This paper sums up the space-time distribution,geological characteristics and geochemical features of Paleozoic intrusive rocks in Western Tianshan,and they are considered as the products of the South and North Tianshan oceanic basin evolution.In the Early Carboniferous and before,Paleozoic intrusive rocks are zonally distributed in the mountains and they are mainly a set of calc-alkaline intrusive rocks related to convergence and subduction of oceanic basins.In the Late Carboniferous and after,Paleozoic intrusive rocks presents planar distribution,and they are mainly a set of Al-rich granite related to collision and a set of post-orogenic K-rich granite. |
