It may also include significant amounts of niobium.<ref name=Handbook/><ref name=Webmin/>
==Background== Wodginite was first described in 1963 for an occurrence in the Wodgina pegmatite, Wodgina, Pilbara Region, Western Australia.<ref name=Mindat/>
Typical occurrence of wodginite occurs in zoned pegmatites in amphibolite. It is associated with tantalite, albite, quartz, muscovite, tapiolite, microlite and microcline.<ref name=Handbook/>
It occurs in pegmatites in a wide variety of locations. The most studied is the Tanco pegmatite in Manitoba, Canada; also in Red Lake, Ontario. It is reported from the Strickland quarry, Portland, Middlesex County, Connecticut; the Herbb #2 pegmatite, Powhatan County, Virginia; the McAllister mine, Rockford, Coosa County, Alabama; the Peerless mine, Pennington County, South Dakota. 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.<ref name=Handbook/><ref name=Mindat/>
