Calcite - Wikipedia

Over 800 forms of calcite crystals have been identified. Most common are scalenohedra, with faces in the hexagonal {2 1 1} directions (morphological unit cell) or {2 1 4} directions (structural unit cell); and rhombohedral, with faces in the {1 0 1} or {1 0 4} directions (the most common cleavage plane). Habits include acute to obtuse rhombohedra, tabular forms, prisms, or various scalenohedra. Calcite exhibits several twinningtypes adding to the variety of observed forms. It may occur as fibrous, granular, lamella

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 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.

What Are the Differences Between the Minerals Calcite and ...

Feb 26, 2020  Chemical Composition. Calcite is a calcium carbonate mineral while quartz is a silicon dioxide crystal. Visually, you cannot tell the difference in the mineral composition, but you can perform a test to determine if the crystal you have is calcite. Calcium carbonate reacts with an acid to produce bubbles on the surface of the crystal.
