中文摘要:
      利卡西市(Likasi)西南部位于加丹加Cu-Co-U-Au多金属弧形成矿带的中南段,成矿条件优越,具有较大的找矿潜力,但地质工作程度相对较低。该文利用ALOS、ETM数据,开展1∶5万遥感地质解译和蚀变信息提取,进一步查明了区内的地层展布、构造格架和矿化蚀变分布等情况,通过野外调查验证,证实了所解译的南北向大断裂和隐伏花岗岩体的存在,在遥感异常区也发现了较好的铜钴多金属矿化。结合成矿地质条件分析,进行找矿预测研究,圈定出层控型、次生富集型和热液脉型铜钴多金属找矿靶区18处。此研究成果对该区部署地质矿产调查等工作具有参考指导作用。
英文摘要:
      The southwestern area of Likasi City is located in the central and south section of Katanga Cu-Co-U-Au polymetallic arc-shaped metallogenic belt, which has favorable ore-forming conditions and great prospecting potential, but the degree of geological work is relatively low. This paper used ALOS and ETM data to carry out 1:50,000 remote sensing geological interpretation and alteration information extraction, further ascertained the stratigraphic distribution, tectonic framework and mineralization alteration distribution, etc. Through field investigation, confirmed the existence of interpreted large NS faults and concealed granite body, also found better copper-cobalt polymetallic mineralization in the remote sensing abnormal areas. Combined with the analysis of metallogenic geological conditions, prospecting prediction research had been carried out, and 18 copper-cobalt polymetallic prospecting targets of stratum-controlled type, secondary enrichment type and hydrothermal vein type had been selected. The research results will provide reference and guidance role for geological and mineral survey in this area.
