В Северном массиве (Чаунский район, Чукотка) определены по химическому составу и описаны ильменит, пирофанит MnTiO3 и псевдорутил Fe2Ti3O9. Содержание Mn в минералах группы ильменита слабо возрастает с циннвальдитизацией гранитов. Псевдорутил сформировался при высокотемпературном окислении ильменита и пирофанита. Пирофанит и эндогенный псевдорутил обнаружены в Северном массиве впервые.

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.
