摘要
四川省青川县青溪铜多金属成矿带形成于晚元古代岛弧环境下的海底火山-沉积作用,后期岩浆活动、构造运动对矿区有叠加改造作用,使其具有多成因、多阶段性。本文通过对前震旦通木梁群细碧-石英角斑岩系化学成分分析,类比同类型矿床,总结该矿带地球化学特征及成矿作用。
Qingxi Tongduo metallogenie belt in Qingehuan CountySichuan Province, formed in seabed volcano - sedimentary in the late Proterozoie island arc environment, with late magmatism, teetonie movement superimposed, which makes the mine deposit area polygenetie and multi-staged. In this paper, through chemical composition analysis of spilite-quartz porphyrite in Tongbuliang group in the former Aurora, with analogy with deposits of the same type, the geoebemieal eharaeteristies and mineralization the deposit belt were summed up.
