摘要
Abstract
The Sarekuobu gold deposit is located on the south margin of Altay mountain, in Xinjiang. It is hosted in pyroclastic rocks and cal careous sandstone of Devonia Kangbutiebao Formation. It is controlled by NW tren d faults. There are three kinds of mineralizing hydrothermal alternation: silica te, skarnization and chloritization. The silicified ores are characterized by hi gh contents of SiO2 and Fe2O3+FeO, while skarnized ores by high contents o f CaO and Al2O3. Different ores are rich in Au, Ag, Cu, Pb, Zn, Bi, Mo, W el ements. Its temperature is about 240℃～310℃. Fluid composition features high C l-/SO42-. The Ar-Ar dating (320 Ma±6 Ma) reflects the latest hydrothe rmal mineralizing age. It is genetically a volcanic exhalation-sedimentary super imposition deposit.关键词
