Dolomite / limestone | Mid-Georgia Gem and Mineral Society

The limestone forms when calcium (Ca ++) and bicarbonate (HCO 3-) combine with the biologic materials found in the sea bed calcite or aragonite. But when the magnesium is introduced in the groundwater, some of the calcite in the limestone is converted to dolomite. It is possible for the dolomite to form in rocks near the seas in arid climates.
