Ikunolite
Ikunolite is a bismuth selenium sulfide and is isostructural with joseite (not approved) and laitakarite. It forms trigonal, columnar, steel-gray, metallic crystals; also occurs as fine-grained, massive aggregates. It was discovered in 1959 and named in 1986 by Akira Kato for the type locality: Ikuno mine, Ikuno-cho-ono, Asago City, Hyogo Prefecture, Honshu Island, Japan, where it occurs with ferberite, bismuth, and bismuthinite in a quartz vein. Other notable localities include: Mullenback uranium deposit, Baden-Baden, Black Forest, Baden-Wurttemberg, Germany; Vysokogorsk deposit, Primor'ye, Russia; Stanos, Chalkidiki Prefecture, Macedonia Department, Greece; Zálesi, Javorník, Olomouc Region, Moravia, Czech Republic; Pangushan mine, Anyuan Co., Ganzhou Prefecture, Jiangxi Province, China; Viceroy mine, Harare district, Zimbabwe; and the Elsmore tin mine, Elsmore, Gough Co., New South Wales, Australia.
