    The analytical results suggest that the dominant volatiles in the ore-forming fluids are H2O,CO2 and CH4,with minor C2H6,H2S,N2 etc. Na+,K+ as well as Ca2+,Mg2+ are dominant cations whereas Cl-and SO42-are major anions. High K and CO2(CH4)constitute the main feature of the ore-forming fluids related to Yanshanian magmatism.
    成矿流体中的主要挥发分为H2O、CO2、CH4,并含少量C2H6、H2S、N2等,液相成分中的阳离子以Na+、K+为主,有少量Ca2+、Mg2+等,阴离子除Cl-外,SO42-的含量也较高。
