A mineral form of crystalline calcium carbonate similar to calcite. It is found in the shells of marine invertebrates such as pāua and in living coral reefs.

A translucent white mineral found in calcium carbonate.

a calcium carbonate mineral with the same chemical composition as calcite, but with a different crystal form [CaCO3]

A calcium carbonate (limestone) mineral, used by shell- or skeleton-forming, calcifying organisms such as corals (warm- and coldwater corals), some macroalgae, pteropods (marine snails) and non-pterop [..]

(n) a mineral form of crystalline calcium carbonate; dimorphic with calcite

One of the two most abundant forms of calcium carbonate in the ocean. The other is calcite.

Aragonite is a mineral form of calcium carbonate (CaCO3) that is often used by marine species to form skeletons and shells.

A mineral species of calcium carbonate (CaCO3) with a crystal structure different from that of vaterite and calcite, which are the other two forms of CaCO3. It is precipitated from ocean surface waters mainly by organisms (e.g., coral) that use it to make their shells and skeletons.

Aragonite is a form of calcium carbonate (CaCO3). It has a different crystal lattice and crystal shape than calcite. See section 2.3.2.2.

 

varies in color and can be white, gray, colorless, yellow, pale green, violet, or brown. It is also the primary mineral that makes up the organic compound commonly known as Mother of Pearl. It was fir [..]

is said to be a grounding stone. It is often used to center and ground physical energies and is said to be very useful during stressful times. Aragonite

A form of calcium carbonate.

<chemical> A mineral identical in composition with calcite or carbonate of lime, but differing from it in its crystalline form and some of its physical characters. Origin: From Aragon, in Spain. (01 Mar 1998)
