Les Montmins Mine (Ste Barbe vein), Échassières, Ébreuil, Allier, Auvergne, France
Mine des Montmins (Filon Ste Barbe), Échassières, Ébreuil, Allier, Auvergne, France
Early 20th century tungsten mine, working wolframite-bearing quartz veins hosted by micaceous slates and granite. Located about 3 km NE of Echassières.
Famous for a wealth of well-crystallised secondary oxysalt minerals (mainly phosphates and arsenates).
The nearby Le Mazet vein (http://www.mindat.org/loc-188986.html) has a very similar mineralogy.
NOTE on the mineral list:
An "Unnamed (Pb-U-Al Phosphate)" described by Cuchet et al. (2000) later turned out to be simply parsonsite, see http://www.mindat.org/min-29119.html.
NOTE on the published mineral photos:
- The photo of "mawbyite" published in Boisson et al. (2000) most probably shows a carminite. Single-crystal XRD studies of crystals with identical shape showed them to be carminite (Uwe Kolitsch, unpublished results).
- The dufrénites shown in the locality photo gallery here on Mindat may in part be natrodufrénite (probably none of them has been analysed (semi-)quantitatively).
