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

    Calcite is a "ubiquitous" mineral. Ubiquitous means "found everywhere." Calcite occurs in igneous metamorphic and sedimentary rocks and is the most commonly encountered carbonate mineral. If you place one drop of cold hydrochloric acid on calcite the entire drop of acid will erupt with bubbles and a vigorous fizz will last for a few seconds.

  • What Are the Differences Between the Minerals Calcite and

    Calcite is a calcium carbonate mineral while quartz is a silicon dioxide crystal. Visually you cannot tell the difference in the mineral composition but you can perform a test to determine if the crystal you have is calcite. Calcium carbonate reacts with an acid to produce bubbles on the surface of the crystal.
