Connellite



Connellite, a copper chlorine sulfate hydroxide hydrate mineral, was identified from Sterling Hill using X-ray methods only. It occurs as tiny blue microcrystals associated with aurichalcite and cuprite or with sarkinite (Peters et al., 1983). Because there was no direct confirmation of the presence of sulfur, there is some possibility, considering the use of nitrogen-based explosives, that this could be buttgenbachite. However, the common occurrence of small amounts of copper sulfates locally and the absence of secondary nitrate minerals at Sterling Hill, suggests that the crystals are connellite. Connellite has not been reported from Franklin. (Dunn, 1995)
