Summary:Sb-and As-sulphosalts are abundant within salband ores from the Sacarimb epithermal Au-Te vein system, South Apuseni Mts., Romania. Similar to the main ore, tetrahedrite-tennantite, bournonite-seligmannite and jordanite-geocronite are the three main groups, although the first group is prominent in the salband, whereas the second prevails in the vein filling. Various Ag- and/or Cu- bearing Bi sulphosalts are also identified and documented here for the first time. These include cosalite, aikinite, lillianite homologues and members of the galena-matildite series. Sulphosalts are the main carriers for a first population of tellurides. Reopening of the veins is interpreted from a range of brecciation textures typified by "emulsion-like" halos surrounding the sulphide/sulphosalt grains. Deposition a second population of tellurides is associated with this event; Bi-sulphosalts relates to this episode only. [I.K.B.]
