Witherite

Witherite

Named for Dr. William Withering, an English mineralogist, botanist, chemist, and physician who was the first to describe the mineral. Occurs typically as a product of alteration of barite in low-temperature hydrothermal deposits, though it is possible that it can be of sedimentary origin with the barium being supplied by volcanic activity in hot springs. Can also be found, albeit rarely, in coal. Witherite is a widespread mineral with many localities worldwide.
