Is It Calcite or Dolomite? | Rock & Gem Magazine
2019-8-27 · When calcium carbonate crystallizes, calcite crystals are the more likely result. But if enough of the element is present, magnesium atoms can substitute for some of the calcium atoms, and the result is calcium, magnesium carbonate, or dolomite. This isomorphic substitution comes into play in limestone and dolostone.
