... of ikunolite and the distribution of Se among various sulfides and sulfosalts at Rędziny, in the metamorphic cover of the Variscan Karkonosze pluton, in Lower Silesia, Poland, have been documented by electron-microprobe analysis. At Rędziny, selenium becomes concentrated at the lower-temperature stages...

...N. L. Markham Abstract The bismuth sulfide mineral ikunolite (Bi 4 S 3 ) was first described by Kato (1959) from the Ikuno mine, Hyogo Prefecture, Japan. A second occurrence of this mineral has recently been found in specimens from the bismuth-molybdenite pipes at Kingsgate in the New England...

... à une température encore plus faible. Les sulfures de bismuth (bismuthinite et un minéral méconnu à Pb–Bi–S), sulfoséléniures (ikunolite) et sulfotellurures (tétradymite, joséite-A, joséite-B et une phase Bi–Te–S méconnue) ont cristallisé à des conditions variables: tétradymite à...

..., lillianite homologues, matildite), native elements (bismuth, electrum), and bismuth chalcogenides (joséite-A, joséite-B, ikunolite, and unnamed Bi-Pb-bearing sulfotellurides). The bismuthinite derivatives are mainly bismuthinite (including cuprian varieties), gladite-krupkaite, paarite, salzburgite...

..., laitakarite, ikunolite, joséite-A, joséite-B) allows compositional fields among naturally occurring Bi–Te–Se–S compounds to be established. New compositional data for ingodite, laitakarite, pilsenite, kawazulite and tellurobismuthite extend previously known compositional limits. Recognized minerals can...

... or josëite-B, there is possibly a complete solid solution series from tellurian ikunolite, Bi 4 (S,Te) 3 , to sulfurian pilsenite, Bi 4 (Te,S) 3 . The unnamed mineral of Yingchen (1986) is apparently tellurian ikunolite. Rucklidgeite, Bi 3 Te 4 , has an antipilsenite, Bi 4 Te 3 , structure type. The unnamed...
