Litochlebite, Ag2PbBi4Se8, a new selenide mineral species from Zálesí, Czech Republic: description and crystal-structure

Original language description

Litochlebite, Ag(2)PbBi(4)Se(8), is a new selenide mineral from the Zalesi uranium deposit, Rychlebske hory Mountains, northern Moravia, Czech Republic. It occurs as irregular grains up to 200 mu m, which form aggregates up to 1-2 mm in size in a quartzgangue. Litochlebite is opaque, dark grey to black, has a dark grey streak and a metallic luster. No cleavage was observed; the mineral is brittle with an irregular fracture. The VHN(10g) microhardness 230 (227-234) kg/mm2 corresponds to a Mohs hardnessof about 3; the calculated density is 7.90 g/cm3. Litochlebite is monoclinic, space group P21/m, with a 13.182(2), b 4.1840(8), c 15.299(2) angstrom, beta 109.11(1)degrees, V 797.3(2) angstrom3, and a: b: c 3.1506: 1: 3.6565. Its average composition (electron-microprobe data) is Cu 0.10, Ag 10.27, Cd 0.05, Pb 11.73, Bi 43.27, Se 32.93, S 0.01, total 98.36 wt.%. The resulting empirical formula, written on the basis 15 apfu, is (Ag1.84Cu0.03)1.87) (Pb1.09Cd0.01)1.10Bi3.99Se8.04.
