Where available, the new aquifer maps are based on an extensive review of available hydro-geological maps, but scientists also had to consult many individual studies. According to Helen Bonsor from the BGS, one of the authors of the paper, the greatest groundwater volumes are in large sedimentary aquifers in North African countries such as Libya, Algeria, Chad, Egypt and Sudan.

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.

The mass stiffness of residual dolomite from

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 .
