dolomite | Formation, Structure, Properties, Uses, & Facts

Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. The bulk of the dolomite constitutes dolostone formations that occur as thick units of great areal extent in many sequences of chiefly marine strata. (The rock dolostone is referred to by only the mineral name—i.e., dolomite—by many geologists.)

Calcite, limestone and marble | Earth Sciences Museum

Limestone is a rock made of calcite. Most limestone is grey, but all colours of limestone from white to black have been found. Scientists test natural rock to see if it is limestone by pouring cold diluted hydrochloric or sulphuric acid (10% solution or vinegar) on it. Limestone gives off bubbles of carbon dioxide.

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

Difference Between Calcite and Dolomite

Dolomite differs from calcite because of the presence of magnesium. • Calcite reacts quickly with acids and produce carbon dioxide bubbles. But dolomite is weakly reacts with acids producing bubbles very slowly. When hot acids or powdered dolomite is used they may react quickly. • Dolomite is slightly harder and denser than calcite.
