Calcite – Virtual Museum of Molecules and Minerals

Calcite is present in about one-third of the soils of the world, primarily in arid and semi-arid regions, where the source was either limestone parent rock or calcareous air-borne dust, although in some climates the soil calcite is the result of coral and shells. Calcareous soils typically have a pH above 7.5. Markgraf, SA, and RJ Reeder. 1985.

Chalk | Properties, Composition, Formation and Uses

These tiny structures are what give chalk its characteristic white color and fine-grained texture. Calcite Matrix: In addition to the coccoliths, chalk rock often contains a calcite matrix that binds the coccoliths together. This matrix forms as the calcium carbonate from the coccoliths dissolves and recrystallizes between the coccoliths ...

Full Guide To Calcite vs. Quartz (This Is The Difference)

Calcite is a much softer stone compared to quartz. Quartz rates 7, while calcite rates 3 in hardness on the Mohs scale. If you're unfamiliar, the Mohs scale of hardness determines a stone's hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score.

Calcite Vs. Quartz

On the Mohs hardness scale, which measures the ability of a mineral to resist scratching, quartz rates a 7, while calcite rates only a 3. This means that quartz can scratch calcite, but calcite can't scratch quartz. You can perform a scratch test using a common steel nail, which has a hardness of about 4.5.
