Gallium-containing chlorite, mica, and magnetite (up to 14, 13, and 5-7 wt % of Ga) along with Ga hydroxides (oxyhydroxides?) were found for the first time in massive sulfide deposit in the Urals. The minerals identified within the cement of chalcopyrite-sphalerite breccias of the Shemur copper-zinc-massive sulfide deposit (Northern Urals) are associated with Ga-enriched sphalerite, chalcopyrite, and, less commonly, pyrite (33-364, 67-363, and 4-230 g/t, respectively).
