History of tectono-magmatic evolution in the Western Kunlun Orogen

<正>Based on the statistical and analytical data on more than 170 isotopic ages published since the 1980s of magmatic rocks, metamorphic rocks, tectonites and ores from the Western Kunlun Orogen, and the characteristics of sedimentation, magmatism, metamorphism and tectonic activities in the region studied in conjunction with geological field investigations and necessary supplementary isotope data, five stages of tectono-magmatic evolution, i.e. Ar3-Pt21 tectono-magmatic active stage (Ⅰ) , Pt22 stable stage (Ⅱ), Pt31-P2 active stage (Ⅲ), T1-T2 stable stage (Ⅳ) , and T3-Q active stage (Ⅴ) can be distinguished in the Western Kunlun Orogen. Moreover, the tectono-magmatic active style and general trend, the characteristics of tectonic settings, etc. of each stage and substage in the region studied are also discussed .
