  • Falkmanite: Mineral information, data and localities.

    www.mindat.org/min-1446.html A mineral closely related to boulangerite, or possibly only a lead-rich variety of the latter. Although the IMA currently considers falkmanite as a grandfathered species, an IMA Commission report (Moëlo et al., 2008) is undecided on the status and concludes that "A solution of the crystal structure of falkmanite is necessary for its definite classification."

Although falkmanite of the ideal composition proposed by Ramdohr & ödman (1940), Pb3Sb2S6, could not be synthesized even with the help of halide fluxes, a phase with composition similar to boulangerite, (Pb5Sb4S11), but with dissimilar X-ray diffraction pattern was synthesized by sulfidation of bournonite at 400 and 500°C.
