Moorhouseite is a rare mineral with the formula CoSO4•6H2O, a naturally occurring cobalt(II) sulfate hexahydrate. It is the lower-hydrate-equivalent of bieberite (heptahydrate) and aplowite (hexahydrate). It is also hydrated equivalent of cobaltkieserite. It occurs together with moorhouseite within efflorescences found in the Magnet Cove Barium Corporation mine in Walton, Nova Scotia, Canada.[6][7]
