Calcite - Origin and occurrence Britannica
2020-8-16 A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth’s calcite is of magmatic (i.e., igneous) origin; it is the chief constituent of the rare rock called carbonatite. Calcite also occurs widely in veins: some of the veins are wholly or largely calcite; others contain valuable ore minerals

Calcite marble mineral Britannica
In calcite: Origin and occurrence. The resulting rocks are calcite marbles. Some calcite marbles, however, appear to have had dolostone rather than limestone precursors; i.e., the dolostone underwent dedolomitization during metamorphism. The calcite grains in some marbles have cleavage planes that are curved; this is usually interpreted to reflect recrystallization during deformation or plastic

Calcite - 1911 Encyclopedia Britannica
The name calcite (Lat. calx, calcis, meaning burnt lime) is of comparatively recent origin, and was first applied, in 1836, to the "barleycorn" pseudomorphs of calcium carbonate after celestite from Sangerhausen in Thuringia; it was not until about 1843 that the name was used in its present sense. The mineral had, however, long been known under ...
