Abstract The barite bed at Fukazawa mine overlies a massive black ore zone and underlies a ferruginous chert bed (tetsusekiei) It is characterized by simple mineralogy which consists predominantly of barite with small but variable amounts of pyrite sphalerite chalcopyrite galena hematite quartz and traces of intimately intergrown chlorite-sericite
