From the earliest times of European contact with the subcontinent, the West Coast of South Africa and its forbidding interior was shrouded in mystery. The illustrious Bartolomeu Dias sailed down the Namaqualand coast in the first few days of and he reputedly sighted the mountains near Clanwilliam and named them Serra dos Reis.

() Onganja Mine - M46/3/ Until now (Smith, ) it was thought that in the central Damara Belt, South West Africa, the Red Granite and the Salem Granodiorite are two magmatic bodies separated by (essentially) marbles.
Three places were discovered, where the marbles are missing; in all three places the Red Granite intrudes the Salem Granodiorite.
Experimental melting done with samples from two of these localities. South Africa occupies the southern tip of Africa, its coastline stretching more than 2, kilometres (1, miles) from the desert border with Namibia on the Atlantic (western) coast southwards around the tip of Africa and then northeast to the border with Mozambique on the Indian Ocean.

The Karoo (/ k ə ˈ r uː / kə-ROO; from the!Orakobab word ǃ’Aukarob "Hardveld") is a semi desert natural region of South Africa.
No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat.
Geology. West Africa is remarkable for its geological variety. Like most of Africa, the region is largely composed of ancient Precambrian rocks (at least million years old; the oldest rocks may be about 3 billion years old), which have been folded and fractured over hundreds of millions of years.
The research focuses on mid- and lower- crustal terrains such as Namaqualand and the Damara belt in southern Africa, but also Archaean terranes in South Africa or Greenland. I am particularly interested in the structural controls of crustal melting, melt migration and the emplacement and assembly of granitic plutons and their effects on crustal.
