The second type of calcium carbonite is aragonite.

It consists of calcium carbonate in crystalline form (aragonite).

It can therefore be observed in the form of crystals on calcite, dolomite or on aragonite.

Aragonite is considered essential for the replication of reef conditions.

It can therefore be observed in the form of crystals on calcite, dolomite or on aragonite.

In aquaria, aragonite is considered essential for the replication of reef conditions.

The structure of the human body contains only four minerals: apatite, aragonite, calcite, and crystobalite.

There are 4 minerals in your organism: apatite, calcite, aragonite and cristobalite.

Human body contains four minerals: apatite, aragonite, calcite, and christobalite.

Aragonite will change to calcite at 470°C, and vaterite is even less stable.

Aragonite will change to calcite at 380–470 °C, and vaterite is even less stable.

Calcium carbonate (CaCO3) comes in two crystalline forms, the minerals aragonite or calcite.

Under high-Mg conditions, its polymorph aragonite will form instead; the marine geochemistry in this regard can be described as an or , depending on which mineral preferentially forms.

The latter transforms to calcite at 380–470 °C, while Vaterite is still less stable.

Under high-Mg conditions, its polymorph aragonite will form instead; the marine geochemistry in this regard can be described as an aragonite or calcite sea , depending on which mineral preferentially forms.
