General Calcite Information Chemical Formula: CaCO3 Composition: Molecular Weight = gm Calcium % Ca % CaO Carbon .
The trigonal crystal system is subdivision of the hexagonal crystal system. It only has one minor difference from the hexagonal system, in that trigonal minerals have threefold symmetry, whereas true hexagonal minerals have sixfold symmetry
The trigonal system is sometimes included in the hexagonal system as a division, called the rhombohedral division with the other hexagonal classes grouped into the hexagonal division. However, the difference between the two ...

Description : Calcite is most common minerals. This name came from Latin word calx, which meaning lime. It is soft gemstone. Calcite crystals are trigonalrhombohedral. Calcite is transparent to opaque. It used for making lenses.

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
Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M ...
