摘　　要：对烧锅营子金矿石英流体包裹体进行了详细研究。流体包裹体均一温度为２８０℃～３２０℃、爆裂温度为２４０℃～２９０℃。成矿流体富含Ｎａ＋、Ｋ＋、Ａｕ＋、Ｃｌ－、Ｈ２Ｏ和ＣＯ２。金以ＡｕＣｌ－形式存在于成矿流体中。ＣＯ２含量与金矿化强度呈正相关。成矿流体ｐＨ值为５．３１～５．５３。成矿流体呈弱酸性、低盐度、低密度、相对氧化环境。The fluid inclusions of quartz in shaoguoyingzi gold deposit are studied in detail,which shows that the homogenization temperature of fluid inclusions ranges from 280320,decrepitation temperature from 240290;the ore-forming fluid is rich in Na+,K+,Au+,Cl-,H2O and the CO2;Gold in the form of AuCl- is existing in the ore-forming fluid ;the content of CO2 is in positive correlation with intensity of gold mineralization;the pH value of ore-forming fluid ranges from 5.315.53;the ore-forming fluid is of weak acidity,low salinity,low density and appears to be of the state of comparative oxidation.
