... are also abundant. Owyheeite, the most important ore mineral, has formed at the expense of andorite via a complex series of replacements. Single crystals of diaphorite, fizelyite, and owyheeite have been studied goniometrically. Diaphorite has been confirmed as monoclinic 2/m with beta =90 degrees 5...
