Marrite With Galena
Miniature, 4.1 x 2.2 x 1.9 cm
Lengenbach, Binntal, Switzerland (TYPE LOCALITY)
ex. Dr. Mark Feinglos Collection A validated specimen of this ultra-rare silver-lead-arsenic sulfide species from Lengenbach. Mark exchanged it from Dr. Jaroslav Hyrsl who in turn obtained it in trade from the Natural History Museum in Bern, Switzerland, in about 1995. Although microcrystalline, the specimen has some display value - more than most such. The two arrows point to the marrite microxls (one or two at each arrow). The rest is galena. The marrite is dull on the surface, as opposed to the galena, which is bright. Really microscope stuff, but very rare, and a silver mineral, so likely of interest to some folks. (TYPE LOCALITY)
