About Kuznetsovite
Formula:
(Hg+2)Hg2+(AsO4)Cl
Colour:
Brown, yellow
Lustre:
Adamantine, Vitreous
Hardness:
2½ - 3
Specific Gravity:
8.64 - 8.82
Crystal System:
Isometric
Name:
Named in honor of Valery Alekseevich Kuznetsov (Валерия Алексеевича Кузнецова) (12 April 1906, Nikolsk, Vologda province, Russian Empire - 4 August 1985, Novosibirsk, USSR), Russian geologist. He was an expert in magmatism and endogenous ore formation (mercury and non-ferrous metals) and discovered the Aktash and Peza mercury deposits (Gorny Altai).
According to Borisov et al. (2003) it might be possible that kuzetsovite - as terlinguaite - contains the [Hg3]4+ polycation.
