Calcite was discovered in 1852 by a mineralogist by the name of John P. Calcite. Calcite is a carbonate mineral that is usually white or colorless, but can have variety of colors due to impurities. It is one of the world’s most important minerals and is the most common. Calcite is one of the softest minerals and can be found in sedimentary and metamorphic rocks.

Calcite has more practical uses than most other minerals. This mineral can be found in limestone and marble which is makes up most of the Earth’s crust. The primary uses for Calcite is for construction uses to create cement or concrete. Calcite is also used for acid neutralization; spread across fields, used in rivers that became acidic by mining and in anti-acid chewable tablets. Limestone and marble which consist of a large amount of Calcite is also used for statues and monuments. The powdered form of Calcite is used as a whitening agent and is common in paint and chalk.

Calcite is the only mineral that bubbles or fizzes when it comes in contact with acid. While most minerals only have few crystal formations, Calcite has over 300. It is also one of the most colorful stones, covering all colors of the rainbow. Calcite contains electric properties. It shows electric impulses under pressure. You can see some samples of Calcite in caves. Most cave formations are result of calcite in the rock. Calcite is a very soft mineral and dissolves

really quickly, creating stalagmites, arches and other cave formations. It forms stalagmites in caves by dissolving when acidic rain water drips through the caves, making the Calcite in the rock dissolve and form stalagmites. Calcite has a glassy luster and a hardness of 3 on a mohs scale.

Many minerals have a lot of similarities and differences to Calcite. For example; Quartz and Calcite are similar...
