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.
