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