Abstract
The Songxi Ag(Sb) deposit is a large-scale new type Ag(Sb) deposit discovered in the early of 1990’s. There exist arguments on its genesis between submarine basic volcanic exhalation and shallow-seated medium-low temperature volcanic hydrothermal filling, with the ore-forming fluid either composed mainly of submarine hot brine, or derived mainly from magmatic water, and some amount of meteoric water. Analyses of N2-Ar-He and He isotopic compositions in fluid inclusions clearly show that the ore-forming fluids of Songxi Ag(Sb) deposit are composed predominantly of formation water or basinal hot brine, the contents of magmatic water in the fluid inclusions are quite low, usually lower than 5%. According to the source of ore-forming fluids, the Songxi Ag(Sb) deposit should be belong to sedimentary basinal brine transformed deposits.
