Barite occurs in hydrothermal ore veins (particularly those containing lead and silver), in sedimentary rocks such as limestone, in clay deposits formed by the weathering of limestone, in marine deposits, and in cavities in igneous rock. It commonly forms as large tabular crystals, as rosettelike aggregates of those crystals, or as divergent plates known as crested barite.
