Abstract: The Shamitumba copper-cobalt deposit is a typical deposit in the central part of the Zam‐ bia-Congo（DRC）copper-cobalt metallogenic belt（Lufrian tectonic belt）in Central Africa. Through the systematic collection，collation and analysis of previous research data，combined with the field geological exploration data of the mining area，the regional geological background，geological characteristics of the deposit，mineralization types and genesis of the deposit are systematically elaborated and discussed. The results show that there are multi-stage geological tectonic movements in the region. The mining area is lo‐ cated at the intersection of the Shamitumba—Kawama anticline and the Ludjiba—Kawama anticline. The continuity of strata and ore bodies is destroyed by structural cutting and dislocation. The Luo an group stra‐ tum exposed in the mining area is a set of clastic rock-argillaceous rock-siliceous rock-carbonate rock al‐ ternating sedimentary formation，which is generally subjected to regional shallow metamorphism. Among them，the mine group（R2）and the Muwaxia group（R4）are important ore-bearing strata of the deposit. The average abundance of Cu element in the Luo an group stratum is 218×10-6 ，which is much higher than the average value of Cu element in the crust sand shale 45×10-6 ，which is the main ore source layer of the deposit. There are four types of mineralization bodies in the deposit. One is the oxidized ore body in
the ' tectonic rock slice' of the Luo an Group mine group，which is developed in the Kawama2，Shamitum‐
ba and M 'Pongo ore sections. The second is the sulfide ore body that occurs in the fourth lithologic section
（R4.2）of the Luo an Group，represented by the R4 ore section and the KT3 ore body of the Atlantic ore
section ; the third is the oxidized ore body in the upper part of the fourth lithologic section of the Luo an
group（R4.2），which is developed in the Atlantic ore section. The fourth is the oxidized ore body that oc‐
curs in the lower part of the fourth lithologic section（R4.1）of the Luo an Group，which is developed in
the SS2-3 and Kawama1 ore sections. The deposit is strictly controlled by stratigraphic lithology，tectonic
action and hydrothermal activity，which belongs to the composite genetic deposit of syngenetic sedimentary
diagenesis-hydrothermal transformation enrichment-supergene oxidation.
