An assemblage of ilmenite, pyrophanite and pseudurutile in Severny granite (the Chukchi peninsula)
- National Mineral Resources University (Mining University)
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.
