Characteristics of ore-formimg fluid of Dahu gold deposit, west Henan Province, China

摘要：

The Dahu is a big gold deposit in the north part of the Xiaoqinling gold area. We take it ad key study for fluid inclusion so as to understand the ore-forming process. The results indicate that the main cations of fluid inclusions are K+, Na+,Mg2+, Fe2+ and the anions are HCO-, Cl-, F-, SO42-.The inclusions have a high CO2 content in gas component. In terms of the parameters it indicates that the fluid inclusions of the Dahu gold deposit exhibits mid-low temperature with mid-low salinity and weak acidity.
