WebThe sandstone is called “Table Mountain Sandstone,” and is accompanied by a second kind of rock called the Graafwater Formation. As a result of its durable rock types, Table Mountain currently has some of the slowest erosion rates on earth, leading Live Science (a science news website) to call it the “ world’s strongest mountain .” WebThe Peninsula Formation, a quartz arenite complex, transgressively overlies the Graafwater and attains a maximum thickness of 1 800m in the Western Cape. The mature, cross bedded sediment is attributed to high energy current and strong winnowing processes on a stable but slowly subsiding shelf. greensheet cypress tx
