Abstract:On the basis of introducing metallogenic setting of the western Qinling area,the features of inclusion and H and O isotopes of the gold deposits in this area are studied.The results show that the gold deposits in this area, occurred mainly in epimetamorphosed clastic rocks and impure carbonate of Devonian,are characterized by multi-stage mineralization.Metallogenic fluids mostly belong to Na+-Ca2+-Cl--SO42- type thermal bittern with rich CO2 and low salinity.They mainly originated from atmosphere precipitation and were influenced by magamatism and wall-rocks of ore deposits.Mineralization was carried out under condition of middle-low temperature,weak reduction,and weak acid.
