Bixbyite

It is commonly associated with beryl, quartz, spessartine, hematite, pseudobrookite, hausmannite, braunite and topaz in pneumatolytic or hydrothermal veins and cavities and in metamorphic rocks. It can also be found in lithophysal cavities in rhyolite. Typical localities are Jhabua and Chhindwara districts, India and the Thomas Range in Juab County, Utah. It is also reported from San Luis Potosi, Mexico; northern Patagonia, Argentina; Girona, Catalonia, Spain; Sweden, Germany, Namibia, Zimbabwe, and South Africa.

Bixbyite was named for the American mineralogist Maynard Bixby (1853–1935), responsible for its discovery in 1897. It should not be confused with bixbite, a red form of beryl; to avoid confusion, this name has been deprecated from the CIBJO and the IMA.
