摘　　要：胶东绿岩型金矿分布在绿岩带中，容矿围岩为斜长角闪岩、黑云变粒岩等。控矿构造为ＮＷＷ向脆韧性断裂带，带内岩石含金平均高达５８８×１０－９，矿体轴向组分分带自上而下为：ＡｓＺｎＳｂＰｂ—ＢｉＡｕＡｇＣｕ—ＳｎＣｏＮｉＭｏ序列；由矿体到围岩水平组分分带表现为对称分布：ＣｕＡｓ—Ｂｉ—ＡｕＡｇＰｂＺｎ—Ｂｉ—ＡｓＣｕ。This paper discussed the general geological characteristics of gold deposits in Jiaodong greenstone belt at first. Based on variation of metallogenetic elements in different horizon and adjoining rocks, we set up vertical zone and horizontal zone of major constituent elements, from upper vein to lower vein it is AsZnSbPb BiAuAgCu SnCoNiMo; from ore body to adjoining rocks it is AuAgPbZn Bi AsCu. Finally, an example for finding gold deposits is given to illustrate good applications of this major constituent element zone.
