An aragonite sea contains aragonite and high-magnesium calcite as the primary inorganic calcium carbonate precipitates. The chemical conditions of the...

Aragonite is a carbonate mineral and one of the three most common naturally occurring crystal forms of calcium carbonate (Ca CO3), the others being calcite...

A calcite sea is a sea in which low-magnesium calcite is the primary inorganic marine calcium carbonate precipitate. An aragonite sea is the alternate...

the prolonged and pronounced stratification results in the formation of aragonite crystals abiotically in the water column. The cumulative warming at the...

seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. Most...

coleoid cephalopods (squids and cuttlefish) have an internalized vestigial aragonite/calcite-chitin shell known as gladius or cuttlebone, which can serve as...

families it is called a gladius. Cuttlebone is composed primarily of aragonite. It is a chambered structure that the animal can fill with gas or liquid...

uses. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at...

near deep-sea hydrothermal vents illustrates the influence of both ancient and modern local chemical environments: its shell is made of aragonite, which...

Carbonate sedimentary rocks are composed of calcite (rhombohedral CaCO 3), aragonite (orthorhombic CaCO 3), dolomite (CaMg(CO 3) 2), and other carbonate minerals...

Trochidae and the Turbinidae. Nacre is composed of hexagonal platelets of aragonite (a form of calcium carbonate) 10–20 μm wide and 0.5 μm thick arranged...
