摘　　要：选取了阳山金矿带单脉资源量最大的311号脉,依托与不同勘探线和不同标高进行系统、科学采样,对13 000多个数据结果进行分析,研究311号脉原生晕特点和不同成矿阶段形成矿体原生晕的叠加规律,得出了阳山金矿带安坝矿段311号脉的构造叠加晕的综合特征:矿体原生晕轴(垂)向分带序列从上至下是As、Sb、Hg→Au、Ag、Cu、Pb→Bi、Mn、Mo、Co,即挥发的、活泼的As、Sb、Hg等元素强异常分布于矿体前缘,Bi、Co的强异常分布于矿体的尾部。建立了构造叠加晕理想模型,预测了盲矿区估算(334?)资源量共计23 234 kg。No. 311 vein, which is the biggest single vein in Yangshan gold ore belt, is selected as research target in this article. Depending on systematic and scientific sampling on different prospecting lines and elevations, and more than 13000 analyzing data, the primary halo characteristics and the superimposed rule of the primary halos formed by different mineralization stages are studied. The comprehensive characteristics of structural superimposed ha- lo of No. 311 vein in Anba ore section have been obtained as follow. The ore body primary halo axis belt sequence from the top to the bottom is As, Sb, Hg→Au, Ag, Cu, Pb→Bi, Mn, Mo, Co. Namely volatile, active As, Sb, Hg abnormity distributes in the front part of ore body, while Bi, Co abnormity distributes in the rear part. The ideal structural superimposed halo model is established. And the total amount of resources （334？） predicted in the blind mining area is 23 234 kilograms.
