初论纳米比亚罗什皮纳地区斑岩型铜矿地质特征——以罗雷铜矿为例

Geological Characteristic of Porphyry Type Copper Deposit in Rosh Pinah in NamibiaL——Setting Lorlei Copper Deposit as an Example

摘要:

纳米比亚罗什皮纳地区成矿地质条件优越，已发现罗雷铜矿、斯克皮铅锌矿、罗什皮纳铅铜矿及海伯超大型铜矿床以及多处Cu，Pb，Zn，Au及Bi等多处矿（化）点，可望形成铜、铅、锌、钼等多金属矿床集中区，找矿潜力巨大。该文在分析该区地质背景的基础上，总结了罗雷铜矿的地质特征，对其成因进行了探讨，并对罗雷铜矿和海伯铜矿之间的大部地区铜矿找矿潜力进行了展望，指出激发极化法是该区隐伏铜矿床勘查的有效物探手段。

Abstract:

There is a huge potential non-ferrous ore concentration area in Rosh-pinah area of Namibia. Lorlei copper deposit, Scorpion zinc deposit, Rosh-Pinah lead-copper deposit and Haib supper copper deposit, as well as numerous mineralized spot of Cu, Pb, Zn, Au and Bi have been found. It is possible to discove those deposits, such as copper, lead, zinc and molybdenum in Rosh pinah area because of the great advantage of geological metallogenic conditions. Based on analyzing geological background, by summarizing the geological characteristics of Lorlei copper mine, and discussing the potentiality of those areas between Lorlei copper deposit and Haib copper deposit for prospecting, it is regarded that induced polarization method is an effective way of geophysical prospecting for exploring this kind of blind copper deposit.
