Calcite: The mineral Calcite spar information and pictures

calcite (kăl`sīt), very widely distributed mineral, commonly white or colorless, but appearing in a great variety of colors owing to impurities.Chemically it is calcium carbonate, CaCO 3, but it frequently contains manganese, iron, or magnesium in place of the calcium.It crystallizes in the hexagonal system, its crystals being characterized by highly perfect cleavage.

Calcite - Wikipedia

Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in ...

Calcite Mineral Data

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).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 ...

Calcite pseudomorphs after gypsum are characterized by a thin, fine-grained rim (15–20 μm) of randomly oriented calcite crystals and a core of parallel columns of calcite crystals in a stockade-like arrangement (Fernández-Díaz et al. 2009). This textural feature is the consequence of an initial nucleation of randomly oriented calcite ...

Calcite: Mineral information, data and localities.

Calcite is often the only mineral present, but in some sedimentary environments, calcite may be associated with dolomite, gypsum, anhydrite, chert, or halite. In hydrothermal veins, quartz and other common vein minerals such as pyrite, dolomite, fluorite, galena, and chalcopyrite may occur with calcite (Kauwenbergh, 2010) .

Calcite Mineral | Uses and Properties

Calcite group structures are taken by nitrates and carbonates of relatively small cations, including Li, Na, Mg, Ca, Fe 2+, Zn, Co 2+, and Cd. The structure of calcite and its related species is ionic and resembles that of NaCl, the place of the spherical Cl ions being taken by planar (CO 3) 2-or (NO 3) 1-groups. These groups are arranged in parallel position in the crystal with their ...
