Improving Mindat.orgUnidentified mineral

23rd Sep 2016 02:22 UTCReiner Mielke Expert

Not really an error however the dark grey mineral in this photo http://www.mindat.org/photo-99259.html is galena. I think it should be mentioned. However it makes me wonder if that is arsenohauchecornite because violarite is usually associated with the galena not arsenohauchecornite. Violarite tarnishes bronze just like this sample and has a good cleavage whereas arsenohauchecornite has a conchoidal fracture which this specimen does not display. Without analysis I would not call this arsenohauchecornite.
