| 中文摘要: |
| 刚果(金)加丹加省 PR12114铜钴矿区位于卢菲利安成矿带刚果(金)段的中西部，为层控氧化铜钴矿矿床，该矿床受罗安组地层及构造控制明显。为了指导在该区域寻找同类型铜钴矿床，本文对其区域地质背景、矿区地质特征、土壤地球化学特征、控矿因素等进行了阐述，分析认为矿区整体为复式向斜，铜钴矿体赋存在罗安组地层内，受北西西—近东西向断裂及推复构造控制，蚀变矿物为孔雀石、蓝铜矿、水钴矿等，地表多见古采坑、民采点，罗安组地层硅化强多为正地形，区内土壤地球化学铜钴异常与地层及矿体位置较吻合，以上可作为重要找矿标志。本文研究成果对该区域内寻找同类型铜钴矿床具有重要的指示意义。 |
| 英文摘要: |
| The PR12114 copper-cobalt mining area in Katanga Province, Democratic Republic of the Congo(DRC), is located in the central and western part of the Congo section of the Lufilian mineralization belt. It is a strati.fied controlled copper-cobalt oxide deposit, which is significantly controlled by the strata and structure of the LuanFormation. In order to guide the search for the same type of copper-cobalt deposits in this area, this paper elabo.rates on the regional geological background, geological characteristics of the mining area, soil geochemical charac.teristics, and ore-controlling factors, etc. The analysis suggests that the mining area as a whole is a compound syn.cline, and the copper-cobalt ore bodies are located in the strata of the Roan Formation, controlled by the northwest-west -near-east-west faults and thrust complex structures. The altered minerals include malachite, azurite, cobalthydrate, etc. Ancient mining pits and folk mining sites are often seen on the surface. The strata of the Roan Forma.tion are highly silicified and mostly have a normal terrain. The soil geochemical copper and cobalt anomalies in thearea are in good agreement with the positions of the strata and ore bodies. The above can be used as important pros.pecting indicators. The research results of this paper have important indicative significance for the search of thesame type of copper-cobalt deposits in this area. |
