About IzoklakeiteHide

Formula:
Pb27(Cu,Fe,Ag)2(Sb,Bi)19S57
Hardness:
3½ - 4
Crystal System:
Orthorhombic
Name:
Named after the type locality: Izok Lake, Mckenzie District, Nunavut, Canada. The Canadian Geographic Names database does not recognize Izok Lake as a valid place name, probably because of its small size.
Giessenite-Izoklakeite Series.

"There is apparently a quasi-continuous solid solution from giessenite to izoklakeite with increasing Sb/Bi ratio, which is nevertheless always < 1 except for izoklakeite of the type locality (∼ 1.04). The main difference is that the monoclinic symmetry of giessenite (Bi-rich) changes to orthorhombic in izoklakeite (Sb-rich) (Makovicky & Karup-Møller, 1986). The exact Sb/Bi ratio at which the symmetry changes is unknown." (Moëlo et al., 2008)
