Abstract

New data showing typical features of the Pasechnoe deposit mineralization have been obtained in results of the comprehensive geological and mineralogical-geochemical investigation. It was revealed that among ore minerals there are sulfides of iron, lead, arsenic and bismuth, the bismuth sulfotelluride, native bismuth, gold, copper, the gold intermetallid – maldonite, sulfosalts of bismuth, lead and silver, oxides and arsenates of bismuth, molybdenite, scheelite, and cassiterite. The bismuth mineralization is closely related to the native gold and is a typomorphic indicator of the forming conditions of the gold mineralization. The revealed characteristic peculiarities in the ore composition and geological structure of the deposit testify the belonging of this ore occurrence to the gold-bismuth formation.
