Calcite Minerals Are Trigonal Rhombohedral

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 - Crystals & Minerals Galore

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380-470°C, and vaterite is even less stable. Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural crystals.

10-6-2007 · If the minerals form without impurities they will take regular shapes visible to the eye, with names like cubic, rhombic, hexagonal, etc. Calcite represents the most common repeating arrangement of CaCO3 molecules (officially called a trigonal-rhombohedral crystal) while aragonite is a different arrangement called orthorhombic, less stable, that will revert to calcite over a long period of time.

Hexagonal crystal family - Wikipedia

The trigonal crystal system is the only crystal system whose point groups have more than one lattice system associated with their space groups: the hexagonal and rhombohedral lattices both appear. The 5 point groups in this crystal system are listed below, with their international number and notation, their space groups in name and example crystals.

ALEX STREKEISEN-Calcite-

The Carbonate, of which the best know is Calcite, contain a discrete (CO 3) 2-radical that may be considered as a single anion in the structure, but is in fact a trigonal planar complex. The triangular nature of the (CO 3 ) 2- radical dominates the structures of the carbonates and results in trigonal (rhombohedral) or orthorhombic (pseudo-hexagonal) symmetry.

Calcite | mineral | Britannica

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 stone formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under rather extreme experimental conditions.
