This week’s Mineral of the Week (MotW) is any mineral from the Alunite Group. So any of the species below (from Mindat).
Chosen as one of them, plumbojarosite (photo), occurs at the Magnet Mine, Tasmania, and that mine is the subject of a presentation to be given on Zoom mid-week. See https://www.facebook.com/events/555303648455392/
