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 .
Limestonenoun
An abundant rock of marine and fresh-water sediments; primarily composed of calcite (CaCO3); it occurs in a variety of forms, both crystalline and amorphous.
Limestoneadjective
Made of or with limestone.
Limestonenoun
A rock consisting chiefly of calcium carbonate or carbonate of lime. It sometimes contains also magnesium carbonate, and is then called magnesian or dolomitic limestone. Crystalline limestone is called marble.
Limestonenoun
a sedimentary rock consisting mainly of calcium that was deposited by the remains of marine animals
Limestone
Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
