The Neoproterozoic Katanga Supergroup hosts one of the world's greatest concentration of sediment-hosted copper-cobalt deposits (Demesmaeker et al., 1963; Cailteux et al., 2005b), and forms the Central African Copperbelt that stretches on both sides of the Zambian – Democratic Republic of the Congo (hereafter Congo) …
What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
The Kamoa copper deposit, 25 km west of the Kolwezi Cu-Co district in Democratic Republic of Congo, is one of the largest high-grade copper deposits in the world.
