Antlerite, a copper sulfate hydroxide mineral, was found as a minor part of a thin green film composed of very fine-grained antlerite, gypsum, and brochantite, encrusting rhodonite and associated with andradite and mica from Franklin. The impure nature of the aggregate precluded the determination of any additional data; the verification was made employing X-ray powder diffraction methods. (Dunn, 1995)
