MCALLISTERITE



Mcallisterite, a magnesium boron hydroxide hydrate mineral, was found by [Dunn] as a colorless to white substrate for hexahydrite and starkeyite from Sterling Hill. It is also found as white formless blebs within starkeyite. It was verified using X-ray diffraction methods, and no analytical or physical data have been obtained. It occurs as part of an apparent efflorescence assemblage, associated with starkeyite, hexahydrite, and gypsum on franklinite-willemite ore from Sterling Hill. It has not been reported from Franklin. (Dunn, 1995)
