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。
There are two types of gold deposits in the Jiaodong Peninsula with different geologic environments and different geologic features: the Zhongshencheng hydrothermal gold deposit and the epithermal hydrothermal gold deposit. In this paper, 328 ore geochemical samples from 5 deep-seated hydrothermal gold deposits and 5 shallow gold deposits were used to confirm that the former is characterized by relatively rich Bi and Au / Ag ratios, and the latter is characterized by high Ag, The Cu, Pb, Zn, As, Sb and Au / Ag ratios are low, and the function formulas for distinguishing two types of gold deposits are established. The model is in line with the study of deposit geology, deepening the understanding of gold deposits in the area.
