Spangolite



Spangolite, a copper aluminum sulfate hydroxide chloride hydrate mineral, was first reported from Sterling Hill by Jenkins (1993a). It occurs as aggregates of 30 micron, hexagonal, bright-green, platy crystals which were verified using X-ray diffraction methods and semi-quantitative chemical analysis methods. This spangolite was found intimately associated with brochantite "in a small, partially oxidized sulfide pod in ore near the footwall contact of the east limb of the Sterling Hill orebody." The specific site was "on the south wall of the 740 crosscut, 800 level, at approximate mine coordinates 730N, 960W" (Jenkins, 1993a). Spangolite has not been reported from Franklin. (Dunn, 1995)
