中文摘要: |
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。 |
英文摘要: |
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, eight deep lead blind orebodies, and 34 deep tungsten blind orebodies have been found. These orebodies occur as stratiform or veins, among which a primary orebody, named Cu1, bends toward northwest and southwest by 20°, respectively. According to the comprehensive analysis of ore-controlling conditions, ore-forming regularity, and ore-body lateral incline charateristics, combined with the exploration results in recent years, it is proposed that the next prospecting direction in this area is mainly in the middle and deep part and the ore-body lateral incline direction to the southwest of No.32 exploration line. |
