Colemanite is a borate mineral found in evaporate deposits. Colemanite is a mineral formed when borax deposits occur, then usually covered with boron containing water. Then, when the water evaporates, the boron remains on the colemanite. The mix of boron and borax form mineral deposits of colemanite.
It was named after William T. Coleman (1824-1893), the owner of the mine where it was found.
