The Goujiahe gold deposit is located in the western Wudang Mountain of South Qinling, which is controlled by ductile slip-shear belt and occurs in sericite chlorite-quartz schist and metamorphic quartz sandstone. The mineralization type is mainly composed of fracture alteration type and quartz vein type mineralization, in which the former formed the main orebody. The main fracture alteration type orebody is distributed in nearly NS-trending fault in stratoid or lenticular form, and the secondary orebodies were filled in NW_and NE-trending secondary faults, forming quartz vein ore bodies. Three metallogenic phases were recognized:the early quartz-sulfide stage, the middle quartz-sulfide-gold and silver stage and the late quartz-carbonate stage. The fluid inclusions of the quartz-sulfide-gold and the silver stage and the quartz-carbonate stage of the main orebody were observed and measured, the D, O, C isotope analysis of different stages of quartz and calcite and dolomite was conducted. The results show that most of fluid inclusions are enriched in liquid primary inclusions in crowded ran-dom distribution. The homogeneous temperature peak is mostly 220℃ and 170℃, the salinity is 1.40% to 14.46% and 1.34% to 7.31%, the density is 0.60~0.97 g/cm³ and 0.86~0.96 g/cm³ for the quartz-sulfide-gold and silver stage and the quartz-carbonate stage respectively. The hydrogen and oxygen isotope study of the two phase yielded 12.9‰~14.5‰ and 11.9‰~13.8‰, and the carbon and oxygen isotope study of calcite and dolomite yielded the values of δ¹³C_V-PDB=-12.4‰~-12.0‰, δ¹⁸O_V-PDB=-18.4‰~-18.1‰, suggesting that the original ore-forming fluids were metamorphic in genesis, characterized by mesothermal and low-salinity nature. Geological and fluid features and metallogenic tectonic background suggest that the Goujiahe gold deposit may be of the orogenic-type mineralization system.
