Abstract

Felbertalite has been found in quartz veins in the Felbertal scheelite deposit as rare elongated crystals < or = 0.5 mm long and < or = 0.2 mm in diameter. It always occurs in contact with Ag-bearing lillianite and a Se-free junoite-like mineral; other associated minerals are cosalite, galenobismutite, members of the bismuthinite-aikinite series, galena, native bismuth and traces of chalcopyrite. Felbertalite is opaque with a metallic lustre; while in reflected light with distinct anisotropy and perceptible bireflectance in air and oil; reflectance approximately 39-43% in air, 25-27% in oil. It has H. 3.3-3.4, D (sub calc) 6.948 g/cm (super 3) . EPMA gave Cu 3.56, Ag 1.02, Pb 30.10, Cd 0.38, Bi 48.3, Te 0.23, S 16.76, = 100.36, leading to the simplified formula Cu (sub 2) Pb (sub 6) Bi (sub 8) S (sub 19) . Indexed XRD powder data are tabulated; strongest lines 2.904(100), 3.768(88), 3.379(77), 3.496(62), 3.432(45) Aa; a 27.637, b 4.0499, c 20.741 Aa, beta 131.258 degrees , V 1745.1 Aa (super 3) ; Z = 2, space group C2/m. The name is for the valley of Felbertal where the mine is located.
