About ChernikoviteHide

Formula:
(H3O)2(UO2)2(PO4)2 · 6H2O
Colour:
pale yellow
Lustre:
Vitreous
Hardness:
2 - 2½
Crystal System:
Tetragonal
Name:
Synthethic material was known first, and referred to as 'hydrogen autunite'. Chernikov reported natural material in 1958, using the same name, but it was never approved by the IMA. The mineral was renamed in 1998 by Daniel Atencio in honor of Andrei Andreevich Chernikov (Андрея Андреевича Черникова) (b. 1927), mineralogist and geochemist at the Fersman Mineralogical Museum, Russia and anexpert on uranium mineralization.
Meta-autunite Group. The most simple valid uranyl phosphate mineral. Compare 'UM1963-03-PO:HU'.
