Unique Carboniferous-Permian tectonic-metallogenic framework of Northern Xinjiang(NW China):Constraints for the tectonics of the southern Paleoasian Domain.
新疆北部石炭纪-二叠纪独特的构造-成矿作用：对古亚洲洋构造域南部大地构造演化的制约

The late Paleozoic tectonic-metallogenic framework of North Xinjiang of the southern Paleoasian Domain was characterized by a serious of Carboniferous-Permian events,including:(1)late Carboniferous-Permian Chinese Altay island arc and its metamorphism,granulite in the Chinese Altay,radiolarian chert and high-pressure/ultra-high-pressure metamorphism;(2)late Carboniferous-early Permian adakites,Alaskan-type mafic-ultramafic complexes,and calc-alkaline magmatism,together with porphyry copper deposits,which occurred in the North Xinjiang;and(3)late Carboniferous ophiolite and island arc volcanic rocks located in the Tian Shan.Combined with the facts that there was no typical foreland basin,no typical collisional-type granitoid,and there were large amount of strike-slip faulting,it is suggested that in the Carboniferous-early Permian North Xinjiang was characterized by the coexistence of compression-extension-strike-slip structures with active magmatism and metallogeny.These phenomena all indicate that there were active margins during the late Carboniferous-early Permian,leading to the notion that the complicated aeeretionary orogeny along the southern Paleoasian Domain may have lasted to the latest Carboniferous-Permian.
