Tripuhyite

Tripuhyite is an iron antimonate mineral with composition FeSbO₄.

The name of the mineral comes from the localilty of Tripuhy, Ouro Preto, Minas Gerais, Brazil, where it was discovered. Hussak and Prior first described the mineral tripuhyite as an oxide of iron and antimony, and assigned it the composition Fe₂Sb₂O₇. When a mineral with composition FeSbO₄ was later discovered in Squaw Creek, New Mexico (US), it was considered erroneously as a new mineral and it was given the name squawcreekite. However, other studies had shown that the original tripuhyite was also FeSbO₄. In 2002, the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA), approved the redefinition of tripuhyite as FeSbO₄ and the discreditation of squawcreekite.
