Cape Fold Belt
The
Cape Fold Belt
is a
fold and thrust belt
of late
Paleozoic
age, which affected the sequence of
sedimentary rock layers
of the Cape Supergroup in the southwestern corner of
South Africa
. It was originally continuous with the
Ventana Mountains
near
Bahía Blanca
in
Argentina
and other fold and thrust belts in
Antarctica
and
eastern Australia
. The rocks involved are generally
sandstones
and
shales
, with the shales (Bokkeveld group) persisting in the valley floors and the erosion resistant sandstones forming the parallel ranges, the Cape Fold Mountains, which reach a maximum height of 2325 m at
Seweweekspoortpiek
(‘Seven Weeks
Defile
Peak’ in Afrikaans).
