A Neoproterozoic (1300 Ma - 900 Ma) continental rift, consisting of several volcanosedimentary basins is situated along the Wand NW -margin of the Kalahari Craton. The basins did not develop contemporaneously but show a younging trend from SW to NE. The lithostratigraphy of these basins is similar, comprising a lower succession of bimodal volcanic rocks and continental red beds. In most basins an upper succession contains grey and green, fine-grained, pyrite-bearing siliciclastics and subordinate carbonates. The rocks have been moderately deformed and experienced lower greenschist facies metamorphism during the Damaran orogeny. Both lower and upper successions host copper mineralisation. Minor copper occurrences in altered basalts are erratic and subeconomic. However, sediment-hosted copper-silver mineralisation is widespread at the base of the marine and lacustrine succession. Mineralisation of economic grade occurs at Klein Aub (Namibia, mine closed in 1987) and Lake Ngami (Botswana). At Klein Aub, isotopic age determinations of copper-sulphides, metal and ore mineral zonation patterns and age-sensitive replacement patterns all document a late or post-deformational origin of the orebodies. At Lake Ngami metal and ore mineral zonation patterns and ore replacement textures indicate ascending diagenetic mineralising fluids prior to the main folding event as zonation patterns were folded together with the surrounding strata. A subordinate type of mineralisation is breccia-hosted and postdates the diagenetic phase.
