纳米比亚Opuwo矿区Nosib砂岩铜矿床成矿特征

Metallogenic characteristics of sandstone copper mines of Opuwo area in Namibia

纳米比亚铜矿资源丰富、矿床成因多,其中砂岩型矿床在纳米比亚的中部和西北部均有发育。Opuwo矿区位于纳米比亚西北部,发育众多的铜矿(化)点,目前还没有发现可以开发利用的铜矿床,其中以砂岩铜矿规模最大、分布最广。文章通过对OU和OM两个砂岩铜矿体的调查研究,根据已有的地质及物化探成果,总结了纳米比亚Opuwo矿区砂岩铜矿成矿规律以及赋存特征,为该区寻求可开发利用的铜矿床提供找矿依据。

Namibia is rich in various type of copper resources, and in the central and northwestern areas, numbers of significant sandstone copper mines have been discovered. Opuwo copper mineralization area is located in the northwest of Namibia, in where there area lot of copper mineralizaions belts（spots）. To date, no copper deposit has been mined in this area. The sandstone copper deposits in Opuwo have the largest tonnage and the widest distribution.Through the invstigation and study on two sandstone copper orebodies of OM and OU, combined with the analysis of the existing geological, geophysical and geochemistry data, this article has summarized the metallogenic characteristics of sandstone copper mines, and attempts to provide key clues for copper exploration in Opuwo area.
