Wodginite

Wodginite is a manganese, tin, tantalum oxide mineral with the chemical formula Mn2+(Sn,Ta)Ta2O8.

[4] Typical occurrence of wodginite occurs in zoned pegmatites in amphibolite.

It is associated with tantalite, albite, quartz, muscovite, tapiolite, microlite and microcline.

The most studied is the Tanco pegmatite in Manitoba, Canada; also in Red Lake, Ontario.

Also from Paraíba and Minas Gerais, Brazil; Krasonice, Czech Republic; Orivesi, Finland; Kalba, eastern Kazakhstan; Ankole, Uganda; Miami district, Zimbabwe and Karibib and Kohero, Namibia.

The figure shows, that the columbite group (including tantalite ) and wodginite can be seen as a superstructure of ixiolite . [ 6 ]
