摘要
东昆仑分布有丰富的多种热液金矿床 ,成矿时代以印支期和燕山早期为主。热液金成矿作用受控于构造热事件。板块构造活动 ,特别是陆内造山作用是热液金成矿作用的原动力。昆中断裂带和昆南断裂带控制区域成矿带 ,北西向次级构造既控制成矿亚带又是主干导矿构造 ,容矿构造亦以北西向或近北西向断裂占优势。
There are plenty sources of hydrothermal gold deposits in eastern Kunlun Mountains. Mineralization ages were mainly in Indosinian epoch and early Yanshanian epoch. The hydrothermal mineralizations are controlled by thermal tectonic events. Original dynamical power was resulted from plate tectonic activities, especially from intracontinental orogenesis. Two regional metallogenic belts are constrained by the middle Kunlun faulted zone and the south Kunlun faulted zone. Secondary NW-structures dominated metallogenic subzones and are major structures as passageway for ore fluids. Host structures dominantly are NW- or near NW-faults too.
