Limestone, Shell, Dolomite | Florida Department .

Limestone is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg(CO 3) 2). It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil corals, urchins and shells.

During the development of calcium carbonate limestone, other elements are present and some of them get into the calcium carbonate structure. One of these is the metal element magnesium. It so happens that magnesium atoms are similar enough in size to calcium, only slightly smaller, and its electron valence matches that of calcium. This means magnesium can substitute for, or take the place of ...
