Baryte, more commonly Barite, (BaSO4) is a mineral consisting of barium sulfate. The barite group consists of baryte, celestite (SrSO4), anglesite (PbSO4), and anhydrite (CaSO4). Baryte itself is generally white or colorless, and is the main source of barium.
Baryte occurs in a large number of depositional environments, and is deposited through a large number of processes including biogenic, hydrothermal, and evaporate among others. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore, and in some meteorites. It is often associated with the minerals anglesite and celestine. It has also been identified in meteorites.
