n.
A common crystalline form of natural calcium carbonate, CaCO3, that is the basic constituent of limestone, marble, and chalk. Also called calcspar.

calcite

(ˈkælsaɪt)
n
(Minerals) a colourless or white mineral (occasionally tinged with impurities), found in sedimentary and metamorphic rocks, in veins, in limestone, and in stalagmites and stalactites. It is used in the manufacture of cement, plaster, paint, glass, and fertilizer. Composition: calcium carbonate. Formula: CaCO3. Crystal structure: hexagonal (rhombohedral)
calcitic adj

cal•cite

(ˈkæl saɪt)

n.
a common mineral, calcium carbonate, CaCO3, found in a great variety of crystalline forms: a major constituent of limestone, marble, and chalk.

cal·cite

(kăl′sīt′)
A usually white, clear, or pale-yellow mineral consisting of calcium carbonate. It occurs in many different forms and is the main component of chalk, limestone, and marble. Calcite is the mineral used to represent a hardness of 3 on the Mohs scale.
