About HolubiteHide

Formula:
Ag3Pb6(Sb8Bi3)S24
Colour:
steel-grey
Lustre:
Metallic
Specific Gravity:
5.899 (Calculated)
Crystal System:
Monoclinic
Name:
Named after Milan Holub (1938 - ), a key Czech geologist specialized in the Kutná Hora ore district.
Chemically similar to oscarkempffite, clino-oscarkempffite, izoklakeite, and staročeskéite. Co-described with also chemically (and stoichiometrically) similar lazerckerite.

Holubite is a new member of the andorite branch of the lillianite homologous series with N = 4.
