| 中文摘要: |
| 在刚果(金)卡通格铌钽矿区已查明控矿构造具有明显磁性特征,与成矿关系密切的花岗岩体具有强放射性；为进一步评价该矿区的找矿前景,为下一步的工作指明方向,使用航空物探磁、放综合测量方法,快速查明了矿区的航磁航放特征,推断出已知矿体受北北东向F1断裂带控制,该断裂带多处走向发生改变,表明该地段有多期次岩浆活动。圈定了与成矿关系密切的花岗岩出露区及下伏方位,沿着花岗岩体边界的F1断裂带开展工作有望找到规模更大的花岗伟晶岩型铌钽矿床。 |
| 英文摘要: |
| In a Nb-Ta mining area in the Congo (Kinshasa), it has been found that the ore-controlling structures have obvious magnetism, and the granite closely related to mineralization have strong radioactivity. In order to further evaluate the prospecting prospect of the mining area and point out the direction for the next work, the aeromagnetic and aeroradiometric characteristics of the mining area are quickly identified by using the comprehensive methods of aerogeophysical magnetic and radiometric survey, and infer that the known ore body was controlled by the NE-trending F1 fault zone, The trend of this fault zone has changed in many places,indicates that there are multiple magmatic activities in this area. the granite outcropping area and underlying orientation closely related to mineralization are delineated. It is expected to find a larger-scale granite pegmatite-type Nb-Ta deposit along the F1 fault zone at the boundary of granite. |
