Abstract
Based on geological exploration work,this article systematically summarizes the geological background and geological characteristics of the deposit,and analyzes the genesis and prospecting indicators of the deposit.The results show that the formation of the copper-cobalt deposit experienced three mineralization periods,namely the sedimentation period,the structural hydrothermal superimposition and reconstruction period,and the oxidation period.The deposit is controlled by strata and faults,and the Neoproterozoic Katangan Lu'an Group strata are the initial source beds.After the diagenetic mineralization period,the structural activities and metamorphism during the Lufeng orogeny reformed the deposit,activating,migrating,and enriching the mineralization elements again.In the oxidation environment near the surface,the copper and cobalt elements are transferred under the action of physical and chemical weathering,forming new secondary enrichment mineralization zones after in situ or off-site deposition.The genesis type of this deposit is summarized as a syngenetic sedimentation-hydrothermal reconstruction-secondary enrichment copper-cobalt deposit.关键词
