Formula:
Pb3Sb2S6
Previously given as Pb5.4Sb3.6S11.
System:
Monoclinic
Lustre:
Metallic
Hardness:
2 - 3
A minerals 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."
Originally described from Bayerland Mine, Pfaffenreuth, Waldsassen, Oberpfälzer Wald, Upper Palatinate, Bavaria, Germany.
