| 摘 要： | 为了解胶东金翅岭金矿成矿流体特征,开展流体包裹体研究。结果表明:矿石石英中主要发育H2O-CO2包裹体、富CO2包裹体和H2O溶液包裹体3种类型,成矿流体均一温度、盐度及密度分别为120～362℃,3.2%～9.0%,0.34～0.94 g/m3,为中低温、低盐度及低密度流体;包裹体液相成分阳离子以K+、Na+、Ca2+和Mg2+为主,阴离子以SO42-、Cl-和F-为主;气相成分以H2O、CO2和CH4为主。结合矿区前人研究,认为该成矿流体是多源流体混合并经历水岩反应演变而成。

| Abstract: | To clarify the characteristics of ore-forming fluid of the Jinchiling gold deposit,fluid inclusion study was carried out.The results show that the inclusions consist of three types: H2O-CO2,CO2 and H2O inclusions.The compositions of cation and anion ions in liquid and gas of the inclusions are mainly respectively Na+,K+,Ca2+,Mg2+;SO42-,Cl-,F-;H2O,CO2 and CH4.The homogenization temperature,salinity and density of the fluid inclusions for the mineralization change from 120 ℃ to 362 ℃,3.2% to 9.0% and 0.34 g/m3 to 0.94 g/m3,respectively,which show that these inclusions belong to middle-low temperature,low salinity and low density fluid.Combined with analyses of other researches,it is found that the ore-forming fluid following water-rock reaction is the mixture of multi-source fluid during its evolution. |
