| 摘 要： | 都兰县察汗乌苏地区位于柴达木盆地东南缘,地处东昆仑多金属成矿带中东部.区内地质构造复杂,岩浆活动频繁,变质作用强烈,区域Pb、Ag化探异常分布集中,铁、铜、铅、锌矿产分布密集,特别是鄂拉山组陆相火山岩系是青海省唯一发现含独立银矿的地层,因此评价研究本区出现的高、大、全Ag、Pb异常特征及其成矿规律,对本区寻找接触交代型银多金属矿具有十分重要的意义.

| Abstract: | The study area is located in the southeast of the Caidam Basin in the middle-east part of the multi-metallogenetic belt in the eastern Kunlun. The region has a complex geological structure, frequent magmatic activity and strong metamorphism. The distribution of Pb and Ag geochemical anomalies are centralized. The Elashan group lava series is the only horizon in Qinghai province where silver ore has been found. The evaluation of Ag and Pb has important significance for researching contact metasomatism silver polymetallic ore in the region. |
