摘要 碰撞造山事件与成矿作用具有强烈的对应耦合关系,而且成矿规模与碰撞的强度呈正相关关系。碰撞造山带的壳幔物质相互作用与成矿作用的强度也呈正相关关系,特别是多期次碰撞造山带,均发生过强烈的壳幔物质相互作用,孕育着丰富的矿产资源。详细地研究了碰撞造山的构造演化过程,划分了相应的成矿构造单元和成矿区带。从碰撞造山的角度提出西天山、西昆仑山、阿尔金-北祁连山、东昆仑山、秦岭-大别山、西南三江、康滇陆缘等造山带为重要的成矿区带。 There is a strong coupling relationship between collisional orogeny and metallogeny and a posi-tive correlation between the size of ore deposits and the strength of collision.In a collisional orogenic belt,the strength of crust-mantle interaction is also positively correlated with metallogeny;especially in a multi-stage collisional orogenic belt,crust-mantle interaction was stronger and the belt contains abundant mineral resources.The tectonic evolution of collisional orogenic belts is studied in detail and corresponding tectono-metallogenic units and metallogenic provinces and belts are distinguished.From the view-point of collisional orogeny,the author proposes that the West Tianshan,West Kunlun,Altun-North Qilian,East Kunlun,Qinling-Dabie,Sanjiang(Three-Rivers)in southwestern China and Kangdian continental-margin orogenic belts are important metallogenic belts.
