System:TrigonalColour:White, Yellow, Red, ...
Lustre:Vitreous, PearlyHardness:3
Member of:Calcite Group
Name:Ancient name. Named as a mineral by Gaius Plinius Secundus (Pliny the elder) in 79 from Calx, Latin for Lime.
Polymorph of:Aragonite, Vaterite
Isostructural with:Nitratine, Otavite


Calcite Group. Calcite-Rhodochrosite Series.

A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent cleavage in most varieties.

Occurrences of Calcite

Geological Setting:Found in most geologic settings and as a later forming replacement mineral in most other environments in one form or another, it is most common as massive material in limestones and marbles. It forms as chemical sedimentary deposits as limestone, can be regionally or contact metamorphosed into marbles and rarely forms igneous rocks (carbonatites). Also is a common gangue mineral in hydrothermal deposits.

Crystallography of Calcite

Crystal System:Trigonal
Class (H-M):3m (3 2/m) - Hexagonal Scalenohedral
Space Group:R3c
Cell Parameters:a = 4.9896(2) Å, c = 17.061(11) Å
Ratio:a:c = 1 : 3.419
Unit Cell Volume:V 367.85 ų (Calculated from Unit Cell)
Z:6
Morphology:Over 800 different forms have been described. Most commonly as acute rhombohedrons or prismatic with scalenohedral terminations, or combinations of the two.
Twinning:At least four twin laws have been described, the most common being when the twin plane and the composition plane are {0112}. Also common with twinning on {0001} with {0001} as the compositional surface, producing re-entrant angles. Uncommon with {1011} or {0221} as twin planes, producing somewhat heart-shaped crystals ("butterfly" twins).
