秦祁昆造山带重要成矿事件与构造响应

古亚洲构造域和特提斯构造域叠加作用的秦祁昆造山带,在中国显生宙大陆壳形成中起着重要作用。其构造演化复杂,成矿作用多样,古生代及中、新生代为重要成矿时期,并伴有元古宙的重要成矿事件。通过秦祁昆造山带成矿事件的研究,将成矿事件与所处的构造位置紧密联系,发现重要成矿事件均对应特殊的构造响应。其中,西昆仑古元古代塔什库尔干磁铁矿,是一个重要的成"铁"事件;阿尔金与东昆仑构造带交汇的祁漫塔格矿集区是一个重要的构造结,新发现的重要矿产是构造转换、多期次构造作用的产物;祁连山北邻龙首山中产出的金川巨型岩浆铜镍矿床,是元古宙大规模幔源物质上涌的岩浆事件;马元铅锌矿是比较典型的MVT型矿床类型,与秦岭的构造演化历程相一致。

Important metallogenic events and tectonic response of Qinling, Qilian and Kunlun orogenic belts

Qinling,Qilian and Kunlun orogenic belts were formed by the superimposition of Paleo-Asian and Tethys structural domains,which had played an important role in the formation of China's continent during Phanerozoic.The tectonic evolution is complex,and mineralization has diverse characteristics.The significant metallogenic periods are Paleozoic,Mesozoic and Cenozoic,with the important ore-forming events occurring in Proterozoic.Based on studies of the ore-forming events of Qinling,Qilian and Kunlun orogenic b...
