| 摘 要： | 尼日利亚的巴古多(Bagudo)锰矿是近年新发现的具有找矿潜力的沉积变质型锰矿床,位于马如—安卡费金铜铁成矿带的西北缘附近。矿区共圈定了3个锰矿区,锰矿体出露于地表,整体呈NW向或近SN向延伸。矿体中的条纹状锰矿石和块状锰矿石均属低磷中铁中品位的氧化锰-硅酸锰混合矿石,且块状锰矿石锰品位低于条纹状锰矿石。目前矿区的勘查深度主要为-50m以上的浅表部分,深部的勘查工作尚未进行。由于锰矿石具弱磁性,故而高精度磁异常的部位具有找锰意义。

| Abstract: | Bagudo Mn deposit is a potential metamorphic sedimentary Mn deposit newly discovered in recent years. It occurs near the NW margin of the Maru-Ankafegin Au-Cu-Fe ore belt. Three Mn-bearing areas are delineated in the property with Mn ore bodies exposed at surface extending NW-SN. Both the massive Mn ore and laminated Mn ore are composed of Mn oxides and Mn silicates with medium Mn grade and low P and medium Fe content. Mn grade of massive ore is lower than that of the laminated ore. Now the Mn ore exploration is confined to 50 m underground. Because Mn is weak magnetically the magnetic anomalies in the property should be potential for further exploration. |
