Sulphosalts, Benjaminite and Matildite from the Ikuno Deposits, Hyogo Prefecture, Japan –Au-Ag Mineralization...Se-bearing benjaminite and matildite are described from the polymetallic zone of the Ikuno deposits, Japan...Japan. The former is the first occurrence in Japan, and is from two separate veins, the Nanten and Daimaru...24)Σ2.98(Bi7.00Sb0.01)Σ7.01 (S10.89Se1.12)Σ12.01 (Nanten) and (Ag2.90Cu0.10)Σ3.00(Bi6.74Pb0.18Sb0.07)Σ6...of the formula Ag3Bi7S12 as the ideal one for benjaminite, and that of matildite based on 4 atoms is Ag1
