An assemblage of Al-low titanite and ilmenite is present in Ti-rich microgranodiorites intruded in the Moldanubian Zone of the Bohemian Massif. Titanite is characterized by coupled substitution (Al, Fe 3+) + (F, OH) ⇔ Ti +O, with a slight excess of (Al, Fe 3+)-OH component over of (Al, Fe 3+)-F component. Ilmenites have FeTiO 3 amount between 86 and 95 mol. % and are partly enriched in the MnTiO 3 (pyrophanite) component (4-10 mol. %). The relatively low content of MnTiO 3 component in ilmenite, together with absence of magnetite suggests that first crystallization phase of microgranodiorites connected with origin of ilmenite started in conditions of low fO 2. However, titanite together with ferroactinolite originated in late-magmatic stage most likely due to hydration reaction such as clinopyroxene + ilmenite + quartz + H 2O = titanite + amphibole during some increasing of fO 2 and fH 2O.
