刚果(金)Shandwe铜矿床成因及找矿方向

Genesis and Prospecting Direction of Shandwe Copper Deposit in Congo(DRC)

加丹加弧形铜钴成矿带是世界第三大铜矿带,带内金属矿产丰富,Shandwe铜矿床位于该带的北西部。使用物探电法勘察技术,并结合地质填图、工程钻探等手段,对该矿床的矿体规模、矿化程度、矿石类型、围岩及蚀变、构造和地球物理特征等进行系统分析。认为该矿床的形成受地层沉积、构造运动、热液流体和风化淋滤等多重因素综合作用和影响,属于沉积-叠加改造-次生富集型层状铜钴矿床,具有很大的找矿潜力。经综合分析提出了2个找矿方向。

Katanga arc copper-cobalt metallogenic belt is the third largest copper belt in the world,which is rich in metal minerals.Shandwe copper deposit is located in the northwest of the belt.Using geophysical electrical prospecting technology,combined with geological mapping,engineering drilling and other means,the ore body scale,mineralization degree,ore type,surrounding rock and alteration,tectonic and geophysical characteristics of the deposit are systematically analyzed.It is believed that the formation of the deposit is affected by multiple factors such as stratigraphic deposition,tectonic movement,hydrothermal fluid and weathering leaching.It belongs to the sedimentary-superimposed transformation-secondary enrichment layered copper-cobalt deposit and has great prospecting potential.Two prospecting directions are proposed by comprehensive analysis.
