A variety of Baryte

A Pb2+-rich (plumboan) variety of baryte deposited by very acid hot springs. Generally also contains minor strontium and minute traces or radium, making recently deposited hokutolite mildly radioactive (although this disappears in a few decades and is no longer detectable in specimens in old collections).

Originally described from Hokuto springs, Taipei Co., Taiwan Province, Taiwan and Peitou, Taipei Co., Taiwan Province, Taiwan.

See also radian barite.
