摘要
河北省大营子金矿床成矿流体地球化学特征为 :成矿流体属Na+ -K+ -Ca2 + -Mg2 + -F--Cl-型 ;盐度为中低等 ;成矿温度为 2 80℃ ;成矿压力约为 74 7MPa ;成矿深度约为地下 3km 属中温中深成热液矿床 矿床形成于中性 -弱碱性且丰对还原条件下 ;成矿流体为混合来源 。
The characteristics of fluid inclusions in Dayingzi gold deposit,Hebei Province are as follows The fluid belongs to Na + -K + -Ca 2+ -Mg 2+ -F - -Cl - type The salinity is low medium degree Ore forming temperature is about 280℃ with pressure 74 7 MPa,which indicates the ore forming depth is about 3 km,thus the deposit belongs to low middle temperature system The fluid originates from mixed resource,i e ,former magmatic water mixed with the later subterranean halogmenic water
