| 中文摘要: |
| 黄草沟银多金属矿床位于东天山博格达—哈尔里克构造带东段的小石头泉地区。矿体产于下石炭统雅满苏组第二亚组(C1y2)火山岩地层中,受断裂构造控制,主要呈脉状；矿石类型以石英脉型为主,金属矿物以辉银矿、黄铜矿、褐铁矿、黄铁矿、闪锌矿为主,非金属矿物以石英、方解石为主；矿区普遍发育硅化、碳酸盐化、绿帘石化等低温蚀变组合。黄草沟银多金属矿床成矿地质特征与浅成低温热液型成矿系统一致,应属于浅成低温热液型银多金属矿床。 |
| 英文摘要: |
| The Huangcaogou Ag polymetallic deposit is hosted in the volcanic rocks of the Yamansu Group in the Bogeda-Haerlike area, eastern Tianslian, NW China. The main orebodies are vein type and controlled by faults. The mineralization styles mainly appear as quartz vein. The ores commonly have vein structures and the main metallic minerals are argentite, chalcopyrite, pyrite, limonite and sphalerite; the gangue minerals are dominated asquartz and calcite. The wide hydrothermal alteration includes silication, carbonatation and epidotization. The study of geological characteristics of the Huangcaogou Ag polymetallic deposit suggested that the mineralization is similar to the epithermal mineralization system. Therefore, we propose that Huangcaogou Ag polymetallic deposit may be considered as an epithermal Ag deposit. |
