About SchirmeriteHide

Formula:
PbAgBi3S6 - Pb3Ag1.5Bi3.5S9
Formula originally suggested to be AgPb2Bi3S7 by Karup-Møller (1973).
Colour:
Lead- to iron-gray
Lustre:
Metallic
Hardness:
2
Crystal System:
Orthorhombic
Name:
Named after Jacob Frederick L. Schirmer, Superintendent of the US Mint at Denver, Colorado. (See http://www.mindat.org/mesg-6-153088.html for discussion on origin of name).
Makovicky and Karup-Møller (1977) redefine schirmerite from the type locality ("Type 2") as a disordered monoclinic phase with a composition intermediate between PbAgBi3S6 and Pb3Ag1.5Bi3.5S9. According to Moëlo et al. (2008) the composition is between those of gustavite and (Ag,Bi)-rich heyrovskýite; they state that such a disordered intergrowth is not a valid species. Schirmerite is currently a discredited species.

Moëlo et al. (2008) discuss whether schirmerite "Type 1" (as defined by Bortnikov et al., 1987) is equivalent to schapbachite or corresponds to an ordered dimorph.
