Columbite: Mineral information, data and localities.
Columbite was long used as a species name but is now split between the iron end-member columbite-(Fe) and the manganese end-member columbite-(Mn) and consequently is the name of an isomorphous series (see Columbite-(Fe)-Columbite-(Mn) Series). The name columbite usually refers to (the more common) columbite-(Fe), formerly known as ferrocolumbite.
Columbite-(Mg): Mineral information, data and localities.
The columbite group name refers to columbium, an old name for the element niobium. Type Locality: ⓘ Muzeinaya pegmatite vein (Muzeinyi pegmatite), Pyandzh River Valley, Gorno-Badakhshan, Tajikistan. This page provides mineralogical data about Columbite- (Mg).
Columbite-(Mn): Mineral information, data and localities.
Name: Originally referred to as manganocolumbite, it was changed to the current form in 2008 (Burke 2008). The name refers to the relationship to the other columbite group species, with dominant manganese. The columbite group name refers to columbium, an old name for the element niobium.
