About KuznetsoviteHide

Valery A. Kuznetsov
Brown, yellow
Adamantine, Vitreous
2½ - 3
Specific Gravity:
8.64 - 8.82
Crystal System:
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.

Classification of KuznetsoviteHide


B : Phosphates, etc., with additional anions, without H2O
O : With only large cations, (OH, etc.):RO4 about 1:1
