The geology of the northern Kalahari region in Botswana is described. The discussion is concerned with the Kalahari Beds which may range in age from the Cretaceous to Recent. The observed occurrences correlate to some extent with the established sequence of the Kalahari Beds in the adjacent Zaire basin. Expressions of six major post-Karroo geomorphological cycles are thought to be present. The older Kalahari Beds of residual and fluviatile silcretes and silcalcretes are relatively thin compared to probably equivalent formations in the main Kalahari region to the south and it is considered that they accumulated in an independent drainage system separated from the main Kalahari basin by the stable Ghanzi ridge. The dune-bedded Kalahari Sands are common to both regions although they may also have been attenuated over the ridge. The youngest deposits are the sands and silts of the Okavango delta which accumu? lated in a downwarped area. A hypothesis is presented linking the early flow of the Okavango with the Zambezi and relating a major change of course and consequential formation of the swamps to Plio-Pleistocene cymatogenic move
