Sedimentary geology of a late Precambrian copper deposit at Kitwe, Zambia
Abstract
A preliminary depositional model is proposed for an orebody in a calcareous mud/carbonate/evaporite sequence of the Zambian Lower Roan Formation. A complex of tidal flat, marine and lagoonal lithofacies are described. Copper grades decrease seawards and laterally around sea floor topographic and lithologic features. Ore shoots have a predictable lineation possibly caused by tidal currents. Features indicative of the contemporaneous nature of mineralization and sedimentation are common.
