Abstract

Bismuth mineralization is studied in sulfde-magnetite ores of the Aktash deposit in Western Karamazar (Northern Tajikistan), which is hosted in the Middle–Upper Paleozoic sedimentary and intrusive rocks. The higher Bi contents are related to the presence of its numerous minerals including native bismuth, bismuthine, Cu–Ag–Pb–Bi sulfosalts (wittichenite, emplectite, aikinit, friedrichite and salzburgite) and Bi oxides (bismite, zavarazkite) in assemblage with galena, chalcopyrite, garnet, pyroxene, epidote and anglesite. The Ag-bearing varieties of wittichenite (Cu,Ag)3BiS3, aikinite (Pb,Ag)CuBiS3 and galenobismuthite (Pb,Ag)Bi2S4 are identifed. Most of the bismuth minerals were frst described not only for this deposit, but for the ore region as well. The mode of occurrence of Bi can be used to refne the genetic features of the deposit.
