东准噶尔碰撞造山作用与花岗岩类及有关金属成矿系列

东准噶尔是中亚－兴蒙巨型构造成矿域的重要组成部分，石炭纪一二叠纪经历了强裂的板块碰撞造山作用，发育多种多样的花风岗类及有关金属矿床。花岗岩类及有关金属矿床的形成演化明显受间造山作用的制约。从碰撞造山前→洋－陆俯冲→陆－陆碰撞→陆内造山挤压－伸展→板内裂谷，区域花岗岩类从大洋Ｍ型科长花岗岩类→岛弧Ｉ型钙碱性花岗岩类→造山隆起区Ｉ型钙碱性花岗岩类、Ｓ型偏碱性花岗岩类→陆内俯冲断裂深熔Ｉ型钙碱性花岗岩类

Collisional orogenesis and granitoids and related metallogenic series from eastern Junggar

Eastern Junggar is an important part of Central Asian-Xingmeng Macroscopic Tectonic-metallogenic domain. During Carboniferous and Permian periods, there happened intensive collision of plates, intracontinental expression-extension and intraplate rift in the area, and well-developed varied granitoids and metallic ore deposits, of which, intraplate fracture anatexis I-type calc-alkali granitoid and related Cu-Au metallogenic series, and post-orogenic extension A 2-subtype alkli granitoid and related Sn metallogenic series were formed. The forming geodynamic setting of the ore-bearing granitoids and the related metallic ore deposits was a very transition stage from collisional compression to extension. The matching of forming of the granitoids and the related metallic ore deposits with collisional orogenesis in time, space and geodynamic setting proposes that the Diagenic and Metalligenic Model for Collisional Orogenesis (by Chen Yanjing) should be the forming model of the granitoids and the related metallic ore deposits in the eastern Junggar area.
