Calcite is one of the most widely distributed minerals on the Earth's surface. It is a common constituent of sedimentary rocks, limestone in particular. It is also the primary mineral in metamorphic marble. It is a chemical or biochemical calcium carbonate corresponding to the formula CaCO 3 and belongs to the carbonate mineral.

calcite (kăl´sīt), very widely distributed mineral, commonly white or colorless, but appearing in a great variety of colors owing to impurities. Chemically it is calcium carbonate , CaCO3, but it frequently contains manganese, iron, or magnesium in place of the calcium.
Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, Ca C O 3 (the other forms being the minerals calcite and vaterite). It is formed by biological and physical processes, including precipitation from marine and freshwater environments.
Most often found as a massive, white to buff or gray, carbonate rock-forming mineral, dolomite is one of the three most abundant carbonate minerals, calcite and aragonite being the other two. Dolomite differs from calcite and aragonite in its crystal structure.
Some interesting facts about calcite are that it is part of the Earth's crust and has the chemical name of calcium carbonate. Its chemical formula is CaCO 3.Calcite is found in nature in many different shapes and colors and is a common mineral that is often collected.

What Is Calcite Used For? Calcite is a mineral used in many ways, serving as a construction material and aggregate, a pigment, agricultural soil additive and an ingredient in pharmaceutical products. Calcite is most often found in limestone and marble, with many applications in those forms.
Calcite commonly forms pseudomorphs after many different minerals and the hard parts of animals. It occurs as a secondary mineral in igneous rocks as a product of decomposition of lime silicates. It is found lining the amygdaloidal cavities in lavas.
Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or x-ray testing.
Calcite is the principal mineral of the rock group known as carbonates. Calcite is a major component in limestone and dolomite. Uses. Calcite is the mineral component of limestone which is used primarily as construction aggregates, and in production of lime and cement.
Dolomite: Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. Learn more about the structure, properties, and uses of dolomite in this article.
Calcite Properties and Meaning. Calcite is a member of the Carbonate family. It comes in many, many beautiful colors. It is found in many, many locations around the world and is readily obtainable. Read more about Calcite crystal healing properties and view the photos below.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.
Calcium Carbonates. Calcium carbonate (CaCO 3) is a chemical compound of calcium. It is the main component of the shells of marine organisms such as oysters, snails shells, pearls, coral and eggshell. Calcium carbonate occurs as minerals aragonite and calcite.
