Calcite: Mineral information, data and localities
Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varietiesCalcite is a rockforming mineral with a chemical formula of CaCO 3 It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks Some geologists consider it to be a "ubiquitous mineral" Calcite Mineral Uses and Properties GeologyCalcite is a carbonate mineral CaCO3 (Fig 113), and the most stable polymorph of calcium carbonate (calcite, aragonite, and vaterite) The color is milky white due to transparency with a Calcite an overview ScienceDirect TopicsCalcite Comments: White, divergent calcite scalenohedral crystals Location: Santa Eulalia, Chihuahua, SA, Mexico Scale: 8 cm © Dave BarthelmyCalcite Mineral Data
