Stratigraphy of copper occurrences in the Zambian Copperbelt
Abstract
Stratigraphic work still in progress has resulted in a revised correlation of the Lower Roan from Chililabombwe to Luanshya. The Upper Roan/Lower Roan boundary has been redefined at several localities and an attempt has been made to correlate the Lower Roan across the Kafue Anticline. At the regional scale, the stratiform nature of major and minor copper occurrences is highlighted. Not only the prominent orebodies but also anomalous copper values can be correlated over a large area. A sedimentary model emphasizing the close association of ore occurrences with transgressions of the Katanga sea is proposed.
