  • The "Acid Test" for Carbonate Minerals and Carbonate Rocks

    The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric

  • What Is the Acid Test in Geology? ThoughtCo

    Every serious field geologist carries a small bottle of 10 percent hydrochloric acid to perform this quick field test, used to distinguish the most common carbonate rocks, dolomite, and limestone (or marble, which may be composed of either mineral).A few drops of the acid are put on the rock, and limestone responds by fizzing vigorously.

  • What's the Difference Between Dolomite and Calcite Marble

    Dolomite marble tiles are composed mainly of calcium magnesium carbonate, while calcite marble tiles contain calcium carbonate. Another important difference between the two tiles that you should note is that dolomite marble tiles tend to be slightly harder than calcite marble tiles.
