The geomorphology of solution cave sequences in the Kalk Bay Mountains, southern Cape Peninsula. BSc thesis, 1996, Shearer, H.

The Kalk Bay Mountains of the southern Cape Peninsula, South Africa, show marked development of pseudokarstic features such as caverns, dolines and grikes. These features have formed over at least 100 million years on supposed inert quartzitic sandstones of the Peninsula Formation of the Table Mountain Group. Pseudokarst on sandstone is relatively rare world-wide and various aspects of cave genesis are highlighted in the Cape Peninsula. Cape Peninsula pseudokarst is relict, occurs at high altitudes above the present water table and could provide clues to palaeoenvironmental conditions during the African erosion period.
The cave systems in the Kalk Bay Mountains occur in at least three levels in the thickly-bedded sandstone. These different levels are the result of differential uplift during the Miocene and Pliocene. The Cape Peninsula Mountains are tabular and blocky, as opposed to the fold mountains of the rest of the South Western Cape. Much more of the overlying sedimentary layers in the Cape Peninsula have also been removed by weathering and erosive processes. The caves can be compared to similar pseudokarst features on sandstone in areas such as Gran Sabana, Venezuela. The acidic water chemistry in Venezuela contributes to a very intensive weathering environment. Present day humid tropical conditions in Venezuela are likely to be similar to palaeoclimatic conditions in the Kalk Bay Mountains, contributing to sandstone cave genesis.

Laterisation on limestones of the Tertiary Wankoe Formation and its relationship to the African Surface, southern Cape, South Africa, 1999, Marker M. E. , Holmes P. J. ,
The existence of erosion surfaces has long been recognised as a macroscale feature of the southern African landscape. Evidence is presented here to demonstrate that laterisation as a soil process affected the calcareous Tertiary Wankoe Formation of the southern Cape. Remnants of the Tertiary African Surface along the southern Cape Coastal Plateau are characterised by deep weathering mantles capped by duricrusts of laterite and silcrete. The limestones have been assumed to be the coastal equivalent of the inland African Surface. Through field mapping of the study locality discussed below, and through sedimentological and geochemical analysis (X-ray fluorescence spectrometry) of selected samples, it was possible to demonstrate that the laterisation process also affected these older Tertiary Limestones. However, the evidence is rarely preserved, and nowhere have complete, intact laterised profiles survived. More often, strong weathering resulted in case-hardening of the topography and the formation of dense calcrete. The implication from this coastal locality is that laterisation as a soil forming process extended from the Mid Tertiary Period until the early Pleistocene Period within this particular sub-region of southern Africa. The significance of this locality within the broader context of the African Surface remnants which occur from the Cape Peninsula in the west to the Knysna area in the east, as well as the palaeoenvironmental significance of laterisation on a substrate which is not conducive to this type of weathering, are also examined.
