【摘要】 胶东半岛存在不同地质环境和不同地质特征的两类金矿床——中深成热液金矿和浅成热液金矿。本文利用５个中深成热液金矿和５个浅成金矿的３２８件矿石地球化学样品，查明前者以相对富含Ｂｉ和Ａｕ／Ａｇ比值高为特征，后者以富含Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ、Ａｓ、Ｓｂ和Ａｕ／Ａｇ比值低为特征，建立了判别两类不同成因金矿床的函数式。模式与矿床地质的研究结论一致，深化了对区内金矿床的认识。更多还原

【Abstract】 Jiaodong peninsula, one of the most important goldproducingarea, exits two genetic types of gold ore deposits of different geological environments and featuresthe mesothermol and the epithermal gold deposit. Using 328 ore samples of 5 mesothermal and 5 epithermal gold deposits in this article, we found that the former is highly composed of Bi and Au/Ag, the latter occurs with highly content of Ag,Cu,Pb,Zn,As,Sb and low Au/Ag. We also made formulas about differentiating types of gold deposits. These achievements are concord with the results of geological research, and thus this work deepens the knowledge of gold deposits in this region.更多还原
