Abstract

Abstract

Sefu deposit is a newly discovered Au-Cu deposit in Gangdese porphyry Cu belt. Its Au orebodies are epithermal type and superimposed on the vein type Cu orebodies. According to detailed geological survey, five periods of hydrothermal activity are distinguished in and around Sefu and Jigongxi. They are Early Eocene magnetite mineralization, Late Eocene-Early Oligocene ductile shearing related one, Early Miocene molybdenum and copper mineralization, and gold mineralization at last. Petrography, microthermometry, laser Raman spectroscopy together with hydrogen and oxygen isotope analysis are conducted on the fluid inclusions in quartz formed during these five periods. It is found that fluid related to magnetite mineralization is the mixture of magma originated aqueous fluid of high temperature, high pressure, high salinity, and formation water. Fluid related to molybdenum mineralization is the mixture of meteoric water and magma originated aqueous fluid of high temperature, high pressure, and high salinity. Fluid related to copper mineralization is the mixture of medium-high temperature, low salinity fluid and containing medium density CO₂, which was originated from magma, and low temperature, low salinity fluid which is from meteoric water. Fluid related to gold mineralization is the mixture of medium temperature, low salinity fluid with low density CO₂, CH₄ and N₂, which was originated from magma, and medium temperature, low salinity fluid, which is from meteoric water. Estimation results of trapping temperature and pressure based on microthermometry also show 1.5-4.1 km erosion had happened before molybdenum and copper mineralization, and 6 km erosion had happened before gold mineralization. After gold mineralization, 0.8-1.2 km erosion had happened. Exploration should focus more on gold orebodies in the near north-south striking faults in Sefu area in future.
