Sand Concretion (Mineral)

Sand concretions are naturally occurring spherical or nodular masses that form when mineral cements such as calcite or iron oxides, precipitate from groundwater and bind loose sand grains together. A small object, such as a shell, piece of organic matter, or even a small rock, acts as a nucleus in the loose sand. The minerals precipitate out of the solution and start to crystallise around the nucleus.This is a perfect example.
