  • What type of rock is a limestone? - Quora

    Mar 05, 2019· Limestone is a naturally occurring sedimentary rock. It consists of calcium carbonate (CaCO3) in its very pure form. Limestone is made by the accumulation of fossils of various marine organisms such as corals, algae, and mollusks and also by deposition of calcium carbonate from oceans, lakes and other water bodies.

    Limestone is a very common sedimentary rock composed largely of mineral calcite. Limestone is mostly grey. Sometimes it is composed of pure calcite, but in most cases, limestone is filled with some impurities such as clay, sand, iron oxide and other materials, which make it show other colors: iron oxide makes it brown, yellow, or red; carbon makes it blue, black, and gray.
