| 中文摘要: |
| 刚果(金) Luben矿区砂岩型铜钴矿位于加丹加省卢本巴西市，地处卢菲利弧成矿带。本次勘查基本查明了该区地质特征、构造及矿(化)带分布。勘查工作主要采用高精度磁法和土壤地球化学(简称化探)面积性测量发现磁异常和次生晕异常，确定铜钴矿成矿有利地段；通过矿区地质测量及槽探圈定地表矿(化)体，随后利用钻探控制矿体延伸情况，最终圈定砂岩型铜钴矿(化)体三个，控制长度分别为 1646 m、 472 m、 1244 m，真厚度分别为 17 m、 3 05 m、 6 47 m；后期钻探控制金属储量铜 23 36万 t，钴 18068 t。通过物化探工作，总结认为采用物化探方法在刚果金寻找铜钴矿效果显著，并且可极大地节约勘查成本；同时也可以为同地区、同类型矿床勘查工作提供一定的借鉴。 |
| 英文摘要: |
| The sandstone copper-cobalt deposit of Luben mining area in Congo (Kinshasa) is located in Lubumbashi city,Katanga,which is located in the Lufilihu metallogenic belt The geological features,faults and mineralized belt of the area have been generally identified through exploration activities in this time The exploration work mainly adopts high-precision magnetic method and soil geochemical survey to nd magnetic anomalies and secondary halo anomalies and determine the favorable areas for copper and cobalt mineralization The surface ore bodies (mineralization) in this mining area have been delineated by geological survey and trenching Then the ore body extensions have been controlled by drilling Three sandstone-type copper-cobalt ore bodies (mineralization) have been de ned,with controlled lengths as 1646 m,472 m and 1244 m respectively and thickness of about 17 m、 3 05 m、 6 47 m;The following drilling have controlled the metal reserves of copper 233,600 tons,cobalt 18,068 tons Through the geophysical and geochemical exploration,it is concluded that the geophysical and geochemical exploration methods are e ective to search for copper and cobalt deposits in Congo (Kinshasa),and can greatly save exploration cost At the same time,this conclusion can also provide some references for prospecting same type of deposits in the areas with same geological conditions |
