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 ...
