What Is Limestone’s Color?

Limestone is a sedimentary rock that is mostly formed of calcium carbonate and is typically white in colour. Limestone, on the other hand, can be tinted by impurities; iron oxide can turn it red, brown, or yellow, while carbon can turn it grey, black, or blue.

Other names for limestone are decided by the look of the rock, how it was formed, its composition, and other variables. Limestone is also known by the following names:

Chalk is a soft limestone with a very thin texture that is often light grey or white. Chalk is made up of the calcareous shell remnants of a variety of microscopic sea creatures.

Travertine is made up of evaporated rainwater that occurs in caverns.

Coquina – Coquina is made up of shattered shell waste seen on beaches.

Lithographic limestone – Lithographic limestone is thick and usually has consistent and fine grain sizes. The grains create thin, easy-to-separate beds, resulting in a highly smooth surface.

Tufa — Tufa limestone is formed when calcium-rich waters, such as those found in hot springs, lake margins, and other places, precipitate.

Fossiliferous limestone is a type of limestone that is made up of shell and skeleton fossils.

Calcium carbonate oolites, which are spheres formed from concentric precipitation on shell pieces or sand grains, make up the majority of oolitic limestone.
