Formation of the giant Luiswishi Cu-Co deposit in the Central African Copperbelt by Neoproterozoic syn-sedimentary-diagenetic processes overprinted by Pan-African orogenic mineralization events

•At Luiswishi Cu-Co deposit, the quartz-, dolomite-, and magnesite-(sulfide) veins occur in silicic, dolomitic, and magnesitic host rocks, respectively.•U-Pb dating of hydrothermal monazites from main ore vein and post-ore pyrite yielded ages of 523 Ma and 506 Ma.•Pyrite from different stages show distinct trace elements and sulfur isotope characteristics.•A two-stage model is proposed by Neoproterozoic syn-sedimentary-diagenetic overprinted by Pan-Afriacn orogenic mineralization events.
