Calcite Crystals and Mineral SpecimensByminerals
Calcite is a rock-forming mineral. It is very common and is found all over the world in sedimentary, metamorphosis, and igneous rocks. Some geologists consider it a "ubiquitous mineral." Calcite is a very common and widespread mineral with many different shapes and colors.
Calcite is an important component of limestone and marble. They are one of the largest carbon deposits on our planet. Calcite has more uses than any other mineral. It is used as a building material, agricultural soil treatment, construction aggregate, pigment, pharmaceutical, and more. Calcite and aragonite are mutually exclusive. Although calcite and aragonite contain the same chemical composition, they differ in the crystal structure. These two minerals can only be distinguished by complex scientific optical tests.
