Paganoite

Comments: Scanning electron microscope photomicrograph of blocky subhedral to euhedral crystals of paganoite and more fine-grained mottled material that is aerugite. (Eur. J. Mineral, 13:169).
Location: Johanngeorgenstadt, Saxony, Germany, mined in the mid-1800’s, nothing was preserved of its previous history until it was located in 1981 by the American mineral dealer David New in the back of a drawer in an old mineral shop in Germany.. Scale: See Image.
