Mineralogy of the Vorontsovskoe gold deposit (Northern Urals). Part 3: sulfosalts

Abstract

This paper continues a series of publications devoted to the mineralogy of the Vorontsovskoe gold deposit in the Northern Urals (Kasatkin et al., 2020, 2021). The article reports on sulfosalts of the deposit, their chemical compositions, as well as unit-cell parameters, optical properties and Raman spectra of some minerals. For eight new mineral species discovered by the authors (auerbakhite, vorontsovite, gladkovskyite, gungerite, luborzakite, pokhodyashinite, ferrovorontsovite, tsygankoite), we provide their density, hardness, refectance spectra and crystal structure. Arsiccioite, benavidesite, bernardite, boscardinite, veenite, weissbergite, vrbaite, heptasartorite, heteromorphite, guettardite, gillulyite, dalnegroite, drechslerite, sicherite, imhofte, christite, cupropolybasite, lafttite, lorandite, manganoquadratite, nowackiite, oyonite, parapierrotite, rebulite, roshchinite, twinnite, philrothite, hutchinsonite, stalderite, ecrinsite and enneasartorite are found for the frst time in Russian Federation.
