Formula: Fe2O3
ⓘ Ilmenite
Formula: Fe2+TiO3
ⓘ Jacobsite
Formula: Mn2+Fe3+2O4
Description: Occure in small amounts in massive Mn-ore (dominated by braunite). In rare cases it's the dominant ore.
ⓘ Johannsenite
Formula: CaMn2+Si2O6
Colour: pale brown

ⓘ Tephroite
Formula: Mn2+2SiO4
Description: Van Der Wel (1974) reported only a few grains in the ore, later A.O. Larsen found masses to 2kg. It's a quite pure tephroite (Tph96Fa3Fo1).
ⓘ Titanite
Formula: CaTi(SiO4)O
