广西大乐铜多金属矿床找矿方向及EH4电磁测深证据

广西大乐铜多金属矿区位于大瑶山西侧铜铅锌多金属成矿带的北段,属典型的后期改造交代—充填型热液矿床。在对矿区实际调研的基础上提出了本区矿化体形成分布受"层+构"双重因素控矿模式制约。根据其控矿特征利用EH4电磁测深技术对其进行地球物理勘探,在显著的物性差异条件下,综合矿区地质情况和物探异常特征圈定异常区14个,为下一步深部找矿方向和深部验证提供了充分的依据,同时深部异常分布特点为提出的控矿模式提供了有力的佐证。

The Ore Prospect Directions and EH4 Electromagnetic Sounding Evidence in Dale Copper Polymetallic Deposit, Guangxi

Dale copper polymetallic deposit in Guangxi is located in the west of Dayaoshan Mountain Cu, Pb, Zn polymetal ore belt north; which is a typical post-reform accountable - filling type hydrothermal deposits. On the basis of the actual research on mine proposed formation of the mineralized zones distributed by "layer configuration" dual mode restricts ore-controlling factors. According to its controlled features use EH4 electromagnetic sounding technique its geophysical exploration in significant physical differences conditions, integrated mining geology and geophysical anomalies delineated anomalous zone 14, as the next step deep prospecting direction and depth verification provide a sufficient basis, while the deep anomaly distribution provides a strong evidence for the ore control model proposed by the author.
