BASSANITE



Bassanite, a calcium sulfate hydrate mineral, was first reported from Sterling Hill by Fred Parker [in a letter in the The Picking Table, 17, #2, 4]. It subsequently was verified by [Dunn] as white, massive microcrystalline material, using X-ray diffraction methods, but no physical or chemical data have been obtained. It has not been reported from Franklin. (Dunn, 1995)
