...Carl Fries, Jr.; Waldemar T. Schaller; Jewell J. Glass Abstract Bixbyite,(Mn, Fe) 2 O 3 , has been found at five localities in the tin-bearing rhyolite in the Black Range in southwestern New Mexico. It occurs as small cubes implanted with specularite and cassiterite on fissure walls and in cavities...

... by coexisting bixbyite). Instead, it suggests a strong Jahn-Teller inhibitory effect to the substitution of Mn 3+ for Al 3+ in the distorted octahedral site of topaz. It is proposed that exsolution of an HF-enriched gas from cooling rhyolitic magma led to local scouring of Al, Si, and trace metals from...

... plugs. Volumes of rock (<1 to 100 km 3 ) in individual complexes composed of 1 to many separate extrusions suggest that the lavas were erupted from small to medium sized magma bodies. In addition to topaz, these rhyolites also contain garnet, bixbyite, pseudobrookite, hematite, and fluorite...

... diagram, the bixbyites from the Thomas Mountain Range contain around 50 at% Fe 2 O 3 and should therefore be considered of pneumatolytic origin, reflecting their formation from a cooling rhyolitic magma. The mineral braunite was first described by W. Haidinger, while its crystal structure remained...

Various examples of this frustrated magnetism are found in spin liquids, spin ices, spin glasses, multiferroics, and unconventional superconductors. A mineralogical example of a frustrated magnet is bixbyite, (Mn 3...
