Calcitenoun
(geology) a very widely distributed crystalline form of calcium carbonate, CaCO3, found as limestone, chalk and marble
Calcitenoun
Calcium carbonate, or carbonate of lime. It is rhombohedral in its crystallization, and thus distinguished from aragonite. It includes common limestone, chalk, and marble. Called also calc-spar and calcareous spar.
Calcitenoun
a common mineral consisting of crystallized calcium carbonate; a major constituent of limestone
Calcite
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as .
Dolomitenoun
(mineral) A saline evaporite consisting of a mixed calcium and magnesium carbonate, with the chemical formula CaMg(CO3)2; it also exists as the rock dolostone.
Dolomitenoun
A mineral consisting of the carbonate of lime and magnesia in varying proportions. It occurs in distinct crystals, and in extensive beds as a compact limestone, often crystalline granular, either white or clouded. It includes much of the common white marble. Also called bitter spar.
Dolomitenoun
a kind of sedimentary rock resembling limestone but consisting almost entirely of the mineral dolomite
Dolomitenoun
a light colored mineral consisting of calcium magnesium carbonate; a source of magnesium; used as a ceramic and as fertilizer
