Tourmaline, rutile, and associated minerals from veinlets cutting chromitites are characteristic of the Kamennoozerskoe occurrence belonging to the Shabrovskii district in the Central Urals. Tourmaline belongs to the dravite–oxy-dravite series and contains Cr (0.52–2.06 apfu), Ni (up to 0.03 apfu), and V (up to 0.02 apfu). Raman spectroscopy indicates Fe3+ in tourmaline. Rutile associated with tourmaline contains, wt %: Sb2O5 4.68–11.69, Cr2O3 2.00–8.02, and WO3 0.88–1.14. It is suggested that tourmaline and associated minerals were formed under oxidizing conditions.
