摘要
中非卢菲里安地区以巨量铜钴资源闻名,同时也赋存大量铅锌资源。通过对该地区铅锌矿床地质特征、矿床成因、成矿期次以及物质来源进行系统的分析总结,获得以下认识:铅锌矿体主要赋存在恩古巴群及罗安群内的碳酸盐岩沉积地层中,属于后生层控型硫化物矿床,与MVT型铅锌矿成矿模式相似;矿化主要集中在680~600 Ma和500~450 Ma 2个时期,前者与卢菲里安造山高峰期相对应,后者则属于后造山期;该地区成矿金属元素以壳源为主,硫化物以海相物源为主,主要受卢菲里安造山活动影响而形成的高盐度热卤水从罗安群及铁镁质基岩中萃取金属元素并在断裂构造发育地区富集成矿。此外,本文还对该地区铅锌矿找矿方向提出了一定建议。
        The Lufilian area of Central Africa is well known for its world-class copper and cobalt deposits,and it also hosts several large epigenetic sulphide Zn-Pb-( Cu) ore deposits. A systematic analysis and summary on the origin,metallogenic phases,material sources and geological characteristics of typical deposits in this region yields the following understandings. Lead-zinc bodies are predominantly present in the carbonate sedimentary strata within the Nguba Group and the Bancroft Formation,thus attributed to the epigenetic stratabound sulfide ore deposit. Similar to the MVT-type lead-zinc mineralization model,the mineralization of this area is mainly concentrated in two periods of 680 ~ 600 Ma and 500 ~ 450 Ma,the former corresponds to the peak of the Lufeilian orogenic period,while the latter belongs to the post-orogenic period; The metallogenic elements in this area are mainly crust sources,and the sulfides are mainly marine sources,the high salinity hot brine formed mainly by the Lufilian orogenic activity that extracted metallic elements from the Roan Group and mafic magma and enrich mines in tectonic active areas. In addition,some suggestions on the prospecting direction of lead-zinc deposits in this region are given in this paper.
