Calcite Mineral Uses and Properties
GeologyUsesFormationConstructionMechanismDietPropertiesSafetySignificanceCalcite is a rock-forming mineral with a chemical formula of CaCO3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a \"ubiquitous mineral\" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. These rocks are extremely common and make up a significant portion of Earth's crust. They serve as one of the largest carbon repositories on our planet.

OverviewEtymologyUnit cell and Miller indsPropertiesUse and applicationsNatural occurrenceFormation processesIn Earth history

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even less stable.

Calcite, the most common form of natural calcium carbonate (CaCO 3), a widely distributed mineral known for the beautiful development and great variety of its crystals. It is polymorphous (same chemical formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under rather extreme experimental conditions.

Aragonite: The mineral aragonite information and pictures

Calcium carbonate forms as both Aragonite and Calcite, and these two minerals only differ in their crystallization.Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or x-ray

Aug 13, 2018  Which mineral crystallizes, calcite or aragonite, depends on the water chemistry. Seawater is full of ions that compete with calcium and carbonate. Magnesium (Mg 2+ ) clings to the calcite structure, slowing down the growth of calcite and forcing itself into calcite's molecular structure, but it doesn't interfere with aragonite.

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.
