| 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280℃;成矿压力约为74.7 MPa;成矿深度约为地下3 km.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,为先期岩浆热液叠加了后期地下热卤水所致.

| Abstract: | 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 |
