Abstract

Abstract

The basement of Junggar basin in the shape of triangle, interspersed in the Tarim plate, Siberia plate and Kazakhstan plate, is the key to initiating the dispute on the Xinjiang geological evolution. The igneous rocks of basement act as the role of "igneous probe". On the basis of the research into the detailed lithofacies, major elements and trace elements, the age dating research results of Sr-d isotope and zircon grain of the igneous rocks in different regions, together with the comprehensive results in Palaeozoic tectonic history, palaeontology, sedimentary formation, igneous rocks, intrusive rocks in the orogenic zone around the basin, indicate that the Junggar basement may have been a product of the soft collision and matching in tectonics between island arc systems located in the periphery of rigid bodies of the Kazakhstan plate, Tarim plates (?) and Siberia plate that occurred in different stages of the Paleozoic and subsequently experienced Mesozoic modification by tectonic-agmatic thermal events (such as the basic magmatic basal erosion).
