About DymkoviteHide

Russian mineralogist Yuriy Maksimovich Dymkov (1926-2014)
Formula:
Ni(UO2)2(As3+O3)2·7H2O
Crystal System:
Monoclinic
Name:
Named in honour of the Russian mineralogist Yuriy Maksimovich Dymkov (1926-2014), a specialist in U mineralogy, the geology of U deposits, and problems of mineral formation, who was one of the first researchers of the U ores of the Belorechenskoye deposit.
Chemically, dymkovite is a Ni-dominant, almost arsenate-free analogue of seelite.
