A pisolite is a sedimentary rock made of pisoids, which are concretionary grains – typically of calcium carbonate which resemble ooids, but are more than 2 mm in diameter.^[1] These grains are approximately spherical and have concentric layers reaching 10 mm in diameter.

The name derives from the Hellenic word for pea. Bauxites, limonites and siderites often have a pisolitic structure.
