Canavesite, a magnesium carbonate borate hydrate mineral, occurs as white sprays of tiny mm-sized crystals on sheared red-willemite ore from Sterling Hill; it has not been reported from Franklin.
Verification was by X-ray diffraction, and nothing more is known of the occurrence. The fluorescence in longwave ultraviolet is violet (pers. comm. R. C. Bostwick). (Dunn, 1995)
