摘　　要：通过对胶东,小秦岭两大金矿产区典型金矿床中成矿期流体成分对比的研究,结合地质特征,得出了胶东金矿床成矿流体与花岗侵入作用有关,小秦岭金矿区矿床成矿流体与变质热液有密切联系的结论,并从流体成分的演化特点推定:胶东金矿有迭加成矿的可能。并对两矿区成矿物质可能存在的迁移方式做了设想。Based on the geological feature and the contrast of fluid composition in mineralizingperiod of the typical gold deposits in Jiao-Dong Gold Field with that in Xiao-Qin-Ling,it is concluded that the mineralizing fluid of Jiao Dong Gold Deposits is related to the granitic intrusion,while Xiao-Qin-Ling Gold Deposits is closely related to the metamorphic hydrothermal fluid.Based on the characteristics of the evolution of fluid composition, it is inferred that Jiao-Dong Gold Deposit is probably of superimposed mineralization.The possible migrational modes of the mineralizing materials in the two fields are inferred.
