摘要
萨热阔布金矿床位于新疆阿尔泰山南缘泥盆系康布铁堡组火山碎屑岩中 ,受断裂控制 ,成矿热液蚀变以硅化、似夕卡岩化、绿泥石化为主 ,硅化蚀变矿石富Fe2 O3+FeO、SiO2 ,而似夕卡岩蚀变矿石富CaO和Al2 O3,各种矿石富集Au、Ag、Cu、Pb、Zn、Bi、Mo、W等多种元素。成矿温度为中温 (2 40℃～310℃ ) ,流体成份以Cl-/SO4 2 -高为特征 ,矿石矿物中石英Ar-Ar年龄 (32 0Ma± 6Ma)反映最终成矿构造热液叠加年龄 。
The Sarekuobu gold deposit is located on the south margin of Altay mountain, in Xinjiang. It is hosted in pyroclastic rocks and calcareous sandstone of Devonia Kangbutiebao Formation. It is controlled by NW trend faults. There are three kinds of mineralizing hydrothermal alternation: silicate, skarnization and chloritization. The silicified ores are characterized by high contents of SiO 2 and Fe 2O 3+FeO, while skarnized ores by high contents of CaO and Al 2O 3. Different ores are rich in Au, Ag, Cu, Pb, Zn, Bi, Mo, W elements. Its temperature is about 240℃～310℃. Fluid composition features high Cl -/SO 4 2- . The Ar-Ar dating (320 Ma±6 Ma) reflects the latest hydrothermal mineralizing age. It is genetically a volcanic exhalation-sedimentary superimposition deposit.
