Résumé / Abstract

The new mineral lautenthalite, a Pb analogue of devillite, is described. Aggregates and single crystals up to 0.5 × 0.3 × 0.03 mm³ in size occur on anglesite and in association with devillite-serpierite in vugs of a silver-rich galena ore which was found near and probably affected by an ancient silver smelter in Lautenthal, Harz Mountains, Germany. The mineral name refers to this locality. Type material is kept at the Mineralogisches Institut, Ruhr-Universität, Bochum, Germany. The mineral is transparent blue, non-fluorescent with a white streak and a vitreous lustre. It shows two good cleavages parallel to (001) and (010). The crystals are platy after {100}, and bounded by {010}, {101}, {102}, {110}, and {514} crystal faces
