| 摘 要： | 索拉沟地区位于青海省东昆仑东部与西秦岭造山带的接合部位,地质构造复杂,岩浆活动较强烈,成矿背景条件良好,是青海省贵金属、铜多金属重要的成矿带之一。根据矿床产出的地质构造环境、成矿特征、矿物组成、电子探针、流体包裹体温压测试及元素组合等特点分析,推测矿床的形成经历了热水沉积成矿和热液叠加改造成矿,索拉沟银多金属矿为热水沉积-热液叠加改造型。

| Abstract: | The Suolagou area is located in the junction of eastern Kunlun Mountains in Qinghai Province and the west Qinling orogenic belt, showing complicated geological structure, relatively strong magmatic activities and a good metallogenetic setting, which is one of an important precious metal, copper-polymetallic metallogenic belt in Qinghai Province. According to geological tectonic setting, ore-forming, characteristics mineral composition, electron microprobe, temperature and pressure testing of fluid inclusions and characteristics of elements association, the forming of deposits undergone hydrothermal sedimentary mineralization and reformed mineralization,.Suolagou silver polymetallic deposit belongs to hydrothermal sedimentary-hydrothermal supraposition reformed one. |
