  • The first and second members of Bilute formation are the major ore-bearing horizons in Haoyaoerhudong gold deposit. The rock types contain carbonaceous meta-siltstone, silty slate, carbonaceous slate and phyllite, etc. Au content is 7.14 times of the crustal abundance in the formation and the carbon content is higher, with values of 1% to 7%. The metallogenic process can be divided into four stages:The homogenization temperature of fluid inclusions in the early quartz vein stage and the quartz-pyrite stage are from 245.2 to 323.3℃ and from 236.9 to 317.5℃ respectively; And the homogenization temperature are between 231.7 and 324.5℃ in the quartz-polymetallic sulfide stage and between 187.6 and 312.9℃ in the quartz-carbonate stage. According to the results of laser raman microprobe, The main liquid phase composition are H2O with minor amounts of CO2 and the main gas phase composition are CO2 with minor amounts of CH4 and N2 in fluid inclusions. Hydrogen and oxygen isotopic features indicate that the ore-forming fluid is closely related to magmatic hydrothermal. A large number of organic compounds in the gas phase composition may be generated in the thermal degradation of organic matter prompted by the magma invasion. The deposit type belongs to the black rock-hosted gold, with a high comparability of that in central Asian metallogenic belt.
