What is the Cape Supergroup?
An 8-km-thick layer of sediment, known as the Cape Supergroup (see below), accumulated on the floor of this rift valley. Thus the Cape Fold Belt “erupted” from the eroding African landscape to form the parallel ranges of mountains that run for 800 km along the southern and south-western Cape coastline today.
How were Cape ranges formed?
The Cape Fold Mountains of South Africa, above, were created as the ancient Falklands Plateau crashed into the African plate. Fold mountains are created where two or more of Earth’s tectonic plates are pushed together.

What are two types of folding?
A symmetrical fold is one in which the axial plane is vertical. An asymmetrical fold is one in which the axial plane is inclined. An overturned fold, or overfold, has the axial plane inclined to such an extent that the strata on one limb are overturned. A recumbent fold has an essentially horizontal axial plane.
