Ilmenite, pyrophanite MnTiO3 and pseudorutile Fe2Ti3O9 are detected by chemistry in Severny granite (Chaunsky District of Chukotka) and described. The Mn content in ilmenite groupe minerals slightly increases with zinnwalditisation high-temperature oxidation of ilmenite and pyrophanite formed pseudorutile. It’s a first occurrence of pyrophanite and endogenous pseudorutile in Severny granite.
