摘要
Kamwale铜钴矿区位于赞比亚—刚果(金)铜矿带的北西部,是非洲中部卢菲利(Lufilian)弧形构造带北西段的一部分。区内地层以新元古界加丹加超群罗安群、孔德龙古群和恩古巴群地层为主。该区经历了多次推覆运动,相互叠加,构造主要为褶皱及断裂(块)构造,整体相对比较复杂。该矿床属于层控型铜钴矿床,矿体主要产于加丹加超群罗安群矿山组(R2)内,呈层状或似层状产出;矿体的产出主要受到中元古界加丹加超群罗安群(ROAN)地层和成矿后的推覆构造作用所控制。通过本次补充勘查工作,综合分析认为主矿体在东西两侧及深部还未进行工程封闭控制,还有扩储空间;矿区中部的成矿地质条件良好,仍有找矿前景。
The Kamwale copper-cobalt mine is located in the northwestern part of the Zambia-Congo(Gold)copper belt and is part of the northwestern section of the Lufilian curved tectonic belt in central Africa.The strata in the area are dominated by the Neo⁃proterozoic Katanga super-group Luo'an group,the Kundelungu group and the Nguba group stratum.The area has undergone many nappe movements,superimposed on each other,and the structure is mainly wrinkle and fracture(block)structure,and the whole is relatively complicated.The deposit is a layer-controlled copper-cobalt deposit.The ore body is mainly produced in the coal section of the Luo'an Formation in the Katanga Group(R2),which is layered or layered.The output of the ore body is mainly affected by the Me⁃soproterozoic.The Katanga Group Luoan Formation(ROAN)stratum and the ore-forming nappe structure are controlled.Through this supplementary survey work,the comprehensive analysis believes that the main ore body has not been closed to the east and west sides of the project,and there is still room for expansion;the prospecting conditions in the middle of the mining area are good,and there is still prospecting prospecting.
