北衙金矿的氧化特征及找矿意义

The Characteristics of Oxidation and Prospecting Significance of Beiya Gold Deposit

北衙金矿是一个与Ｆｅ，Ｐｂ，Ｚｎ，Ａｇ、伴生的氧化型金矿，由于原生矿石中物质分布不均匀，矿体的氧化程度也存在明显的差异．通过对氧化带的研究，发现矿石中Ａｕ，Ａｇ，Ｐｂ，Ｚｎ为明显的正消长关系．一般来说，矿体氧化带发育并出现铅、锌的次生矿物，金的含量也比较高。

Beiya gold deposit is an oxidizing type gold dedeposit accompanied with Fe,Pb,Zn,Ag.Due to the fact that the distribution of the materials in the ore is nonhomogeneous,the oxidizing degree of ore bodies is obviously different.On the basis of studies of oxidation zone,it is discoveried that the Au,Pb,Zn,Ag in ore are obviously positive correlation.The oxidation zone of the ore bodies is well devoloped and in which secondary minerals of lead and zinc are appeared,the gold content is higher.It is a profitable position of mineralization.
