Summary:New data on the composition of jordanite–geocronite Pb–Sb–As sulfosalts in the vein–disseminated gold ore at the Berezitovoe deposit were provided. Within the studied quartz–sulfide sample, some grains of Pb–Sb–As sulfosalts, uniform in composition and azonal, are drastically different from each other in As and Sb contents forming a quasi-continuous range of solid compounds from jordanite to geocronite. Jordanite–geocronite minerals at the Berezitovoe deposit (relative to the Darasun deposit) are characterized by a higher Pb concentration with a low polymetal total. It is assumed that such typomorphic features of the composition of Pb–Sb–As sulfosalts are indicative of specific formation conditions of gold mineralization in polymetallic ores at the Berezitovoe deposit.
