his is a fnal paper in a series of publications devoted to the mineralogy of the Vorontsovskoe gold deposit in the Northern Urals. The article reports on oxygen compounds (oxyhalides, oxides, hydroxides, carbonates, sulfates, tungstates, phosphates, arsenates and silicates) of the Vorontsovskoe deposit, their chemical composition and, for selected minerals, unit-cell parameters and optical properties. Armenite, claudetite, ramsdellite, hingganite-(Nd) and chapmanite are found for the frst time in Russian Federation. As a conclusion for the entire series of publications, the general features of mineralogy of the Vorontsovskoe deposit are discussed, thanks to which it is considered as a unique mineral locality not only in Urals but in general in Russia.
Keywords: Vorontsovskoe deposit, Northern Urals, oxygen compounds, frst mineral fnds in Russia.
