La calcite a servi à l'établissement des lois fondamentales de la cristallographie. Elle est rhomboédrique. Ses formes sont très nombreuses dans la nature. Citons, parmi les plus fréquentes : le rhomboèdre, le scalénoèdre, le prisme hexagonal. Elle possède trois clivages parallèles aux faces d'un rhomboèdre. Sa densité est 2,71 et sa dureté 3. C'est un cristal uniaxe négatif présentant une forte biréfringence (spath d'Islande). La craie est une variété de calcite.

L'indice de saturation calcique (ISC).

Pour déterminer l'indice de saturation on peut utiliser soit l'adjectif "calcique" soit la locution "de la calcite". Le terme "calcique" signifie "relatif au calcium"; il est moins précis que "calcite" qui désigne le carbonate de calcium (CaCO3), forme la plus répandue du calcium dans la nature. Au Québec, "indice de saturation calcique" est cependant le terme le plus employé. 7, record 7, French, - indice%20de%20saturation%20calcique
