A concretion is a compact mass of mineral matter, usually spherical or disc-shaped, and they vary greatly in size. They usually form early in the burial history of sediment, before the rest of the sediment has hardened into solid rock. Concretions occur when a considerable amount of cementing material collects locally around a nucleus, often organic (a leaf, tooth, a section of fossil or shell or dead matter) and commonly a marine invertebrate.
