Geology. The Magaliesberg has ancient origins. Its composition is ascribed to successive geological processes over a very protracted history. Its quartzites, shales, chert and dolomite were deposited as sediments in an inland basin on top of a 3 billion year old Archaean Basement Complex, known as the Kaapvaal process of sedimentation lasted for about 300 .

In South Africa, the stiffness of dolomite residuum has traditionally been viewed as relatively low. For reasons of economy, available dolomite residuum stiffness data mostly stem from plate load tests on each of the materials forming the residual profile, typically chert gravels and wad, rather than on the actual mix of materials that typically occurs in situ .

So the name "Dolomite" became soon established, and in 1794 Richard Kirman introduced the Dolomite as a new mineral; the name from there became used to name the dolostone rocks and finally gave the Dolomites their actual name. In the 19th century the genesis of both the Dolomite Mountains as the rock forming them became a major problem in geology.
