Chesnokovite

This page is currently not sponsored. Click here to sponsor this page.
Russian mineralogist Boris Valentinovich Chesnokov
Formula:
Na2[SiO2(OH)2] · 8H2O
Crystal System:
Orthorhombic
Name:
In honor of Russian mineralogist Boris Valentinovich Chesnokov (Борис Валентинович Чеснокова) (11 June 1928 - 25 October 2005). He was a specialist in the mineralogy of the Southern Urals and founder of a Russian school of mineralogy technogenesis. He also described about 10 new minerals.
Alters to Thermonatrite and Opal when left exposed to normal atmospheric humidity.
