DOLOMITE AND LIMESTONE Executive Summary MgCO Limestone is defined as a calcareous material or rock with a limestone content (CaCO 3) of at least 70%. Lime, limestone and dolomite products are used in four principal industries in South Africa: Cement manufacturing, metallurgy (steel refining), manufacturing and agriculture (fertilizers, fungicides,

About 250 million years ago, the present-day arc of the Alps was part of the continent Pangea, which was located far to the south, in the Earth’s tropical zone. Given the presence of mollusks, algae, coral and fish, this area saw massive limestone production.

The difference between dolomite and lime is the presence of magnesium in its structure, so that 50% of it is calcium carbonate and 40% of magnesium. In the decomposition of dolomitic limestone, about 22% of calcium and 11% of magnesium can

This can produce a porosity zone in the strata where dolomitization has occurred. These pore spaces can be traps for subsurface fluids like oil and natural gas.
