山东黄埠岭金矿床7 号脉原生晕地球化学特征

黄埠岭金矿床是蚕庄金矿的主要生产采区之一，已开采黄金金属量1. 6 t 以上。利用原生晕地球化学研究对危机矿山进行深部矿体定位预测以解决后备储量不足的问题。黄埠岭金矿床7 号脉原生晕地球化学的指示元素相关性、元素组合、元素含量空间分布等特征研究表明: 因子得分F4、F5 增高可作为矿体上部的标志; 而Hg /Ni 等累加指数值增高时为矿体的上部，反之为矿体的下部。本研究还评价了其深部含矿性并圈定了3 个深部靶区。

Geochemical characteristics of primary halo in vein No.7 of Huangbuling gold deposit in Shandong

Huangbuling gold deposit is one of the main mining areas of Canzhuang gold deposit, and the exploitation of gold mining has been more than 1.6 t. The authors forecast deep seated orebody location for crisis mines using primary halo geochemistry to solve the problem of inadequate reserves. The study of correlation of indicator elements, elements combination, and spatial distribution charactrisitics of elements contents for primary halo geochemistry of vein No. 7 in Huangbuling gold deposit shows that the high values of factor scores F4 and F5 can be used as the signs of the upper part of orebody. The high values of cumulative index （Hg/Ni） can be used as the sign for the upper part of orebody, and otherwise as the lower part. The study has also evaluated the ore-bearing of deep orebody, and blocked out three target areas.
