摘要: Musoshi铜矿床位于中非赞比亚-刚果(金)铜钴成矿带内,与Konkola铜钴矿床毗邻,为 该成矿带上的典型矿床。以Musoshi铜矿床最新勘查资料为依据,对矿区地层、构造、矿化特征、矿石 矿物组合等进行阐述,并对矿床成因进行探讨。研究结果表明,矿床大地构造位于卢弗里安成矿带 (加丹加多金属成矿带),铜矿化(体)均产于加丹加系迈恩统的下罗安阶中,含矿岩性为粉砂岩及泥 质粉砂岩,矿化富集程度与岩体中矿物质富集程度呈显著的正相关;矿化具有明显的层控性,沿走 向、倾向连续性均较好,矿石矿物以黄铜矿、黄铁矿、辉铜矿、孔雀石为主,脉石矿物主要包括石英、钾 长石、白云母;加丹加系罗安群是矿床形成的矿源层,经后期构造作用、热液叠加改造作用等,最终形 成同生沉积成岩-热液改造富集-表生氧化的复合成因矿床,矿区深边部仍具有巨大的找矿潜力。

Abstract: The Musoshi copper deposit is located in the Zambia-Congo(DRC)copper-cobalt metallo⁃ genic belt in Central Africa,adjacent to the Konkola copper-cobalt deposit,and is a typical deposit in the metallogenic belt. Based on the latest exploration data of Musoshi copper deposit,the strata,structure,min⁃ eralization characteristics and ore mineral assemblage of the mining area are expounded,and the genesis of the deposit is discussed. The results show that the geotectonic location of the deposit is located in the Lufrian metallogenic belt(Katanga polymetallic metallogenic belt),and the copper mineralization(body)is pro⁃ duced in the lower Luo 'an stage of the Mai 'en series of the Katanga system. The ore-bearing lithology is siltstone and argillaceous siltstone,and the degree of mineralization enrichment is significantly positively correlated with the degree of mineral enrichment in the rock mass. The mineralization has significant strat⁃ abound characteristics,and the continuity along the strike and dip is good. The ore minerals are mainly chal⁃ copyrite,pyrite,chalcocite and malachite,and the gangue minerals mainly include quartz,potassium feld⁃ spar and muscovite. The Katanga system Luo 'an group is the ore source layer formed by the deposit. After the late tectonic action and hydrothermal superposition transformation,the composite genetic deposit of syn⁃ genetic sedimentary diagenesis-hydrothermal transformation enrichment - supergene oxidation is finally formed. The deep edge of the mining area still has great prospecting potential.
