盐田桥铜多金属矿床位于湘东金银铜铅锌成矿带,区内北东向隆起带活动强烈,岩浆活动频繁,成矿地质条件十分优越。区域性长寿—衡阳—观音阁断裂带是区内主要控矿构造,它既是导矿构造,又是容矿构造,矿体全部分布于硅化构造角砾岩带膨胀部位内。目前地表已发现1条铅矿体,深部探获20条铜盲矿体、8条铅盲矿体和34条钨盲矿体,矿体呈脉状、似层状产出,其中主矿体Cu1具中间向西南、西北侧伏20°特征。根据区内控矿条件、成矿规律及矿体侧伏特征的综合分析,结合近几年勘查成果,提出了该区下一步找矿方向主要在中深部及32号勘探线往西南方向矿体侧伏方向。

The Yantianqiao copper polymetallic ore deposit is located in the gold-silver-copper-lead-zinc metallogenic belt of eastern Hunan province.The northeastward uplift and the magmatism in the deposit are active,which is beneficial to the ore formation.The regional Changshou-Hengyang-Guanyinge fault zone in the Yantianqiao ore deposit not only controls the formation of the Hengyang basin and the outcropping of many rock bodies but also is the ore-controlling structure in the deposit.So far,one shallow lead orebody,20 deep copper blind orebodies,eig...
