摘要
该铜钴矿区位于刚果(金)加丹加省利卡西市东北部,勘查工作采用高精度磁测扫面快速、有效地划分了构造,圈定了磁异常靶区;通过土壤地球化学测量,对物探异常性质进行了划分,进一步缩小靶区;地表地质测量大致查明了矿区内恩古巴群Likasi组下段(Ng^(1.1)),中上段(Ng^(1.2-1.3)),恩古巴群Monwezi组(Ng^(2))的地层、岩石、构造等,确定了向斜、背斜构造位置;在槽探施工过程中发现了两条铜矿(化)体和一处铜异常点,为矿区后续钻探、勘查提供依据。
The copper and cobalt mining area is located in the northeast of Likassi City,Katanga Province,Congo(DRC).High-precision magnetic scanning was used to quickly and effectively divide the structure and delineate the magnetic anomaly target area.Through soil geochemical survey,the geophysical anomaly properties are classified and the target area is further reduced.The surface geological survey has roughly identified the strata,rocks and structures of the lower section(Ng^(1.1)),middle and upper section(Ng^(1.2-1.3))and Monwezi formation(Ng^(2))of the Encuba Group in the mining area,and determined the synclinal and anticlinal structure positions.Two copper oredodies(or mineralization bodies)and one copper anomaly were found in the process of trough exploration,which provides a basis for subsequent drilling and exploration in the mine.
