Dunes of the Southern Kalahari,that are both marginally dynamic as well as more stabilised, research has focussed both on the processes operating on partially and variably vegetated surfaces, and the palaeoenvironmental histories of dunefield accumulation. Whilst commonly classified as linear dunes, this chapter examines the rang
