摘要
在纳米比亚西北部东卡奥科带寻找铜矿床过程中,通过对铜矿化及伴生组合的激电异常与钻孔揭露结果比对分析,发现激电方法能够较好地确定铜矿化富集部位,激电异常在该区的找矿中有明显的指导意义.诺西布群砂岩与其上覆地层的泥质粉砂岩、页岩、白云岩形成氧化-还原的成矿环境,断裂与褶皱构造为成矿物质的运移、富集提供了空间.研究矿化类型、矿化富集部位和激电异常特征,是提高该区找矿效果的重要途径.
In the process of prospecting copper ore in east Kaoko belt of northwestern Namibia, by comparison analysis between the copper mineralization and associated combination of induced polarization anomaly and drilling revealed results, it can be seen that induced polarization method can better determine copper mineralization enrichment sites, therefore, the induced polarization anomaly have obvious ore-prospecting significance in the region. Nosib group sandstone and its overlying strata of argillaceous siltstone, shale, dolomite formed oxidation-reduction metallogenic environment, fracture and fold structure provides space for metallogenic material migration and enrichment. The mineralization types and mineralization enrichment parts and induced polarization anomaly characteristics, is the important way to improve the prospecting effect in the region.
