Geelwal Karoo mineral sand deposit, on the west coast of South Africa. Tectonic activity, which results in coastlines rising from the ocean, may also cause a beach system to become stranded above the high-water mark and lock in the heavy mineral sands. Similarly, a beach system that is drowned by the subsidence of a coastline may be preserved ...
The sand, silt and mud deposits were lithified by pressure and then folded during the Cape Orogeny to form the Cape Fold Belt, which extends along the western and southern coasts.

The central highland, or peak, of the crater is surrounded by a small sand-filled trough; this, in turn, is surrounded by a larger circular trough. Linear rock ridges alternating with light orange sand deposits cross the image from upper left to lower right; these are called yardangs by geomorphologists. Yardangs form by wind erosion of exposed ...
