First Find of Trace Metal Minerals at the Albaza Gold Deposit
- 6 Downloads
The results of mineralogical–geochemical study of the Albaza gold deposit (Khabarovsk Krai) are presented here. The ore mineral assemblage, in addition to already known sulfides of iron, arsenic, lead, zinc, and copper, contains sulfides of Sb, Bi, and Mo, as well as native bismuth, bismuth tellurides, cobalt sulfoarsenide, nickel sulfoantiminide, silver sulfobismuthide, lead–antimony–bismuth sulfosalts, and oxides of tin and titanium, among others. These features of the ore chemical composition suggest attribution of the deposit to a gold–trace metal formation. The genesis of the deposits of this formation is related to granitic magmatism that occurred at the transform continental margin under conditions of movement of the lithospheric plates.
