Russian mineralogist and geochemist Fedor Vasil’evich Chukhrov.
Formula:
Ca3CeAl2(SO4)F13 · 12H2O
Colour:
white, with a lilac tint
Lustre:
Vitreous, Greasy, Pearly
Hardness:
3
Specific Gravity:
2.274 - 2.398
Crystal System:
Isometric
Name:
Named in 1978 by Kurt Walenta for its relationship to chukhrovite-(Y) (at the time, simply chukhrovite). The root name is for Fedor Vassil’evich Chukhrov (1908-1988), Russian mineralogist and geochemist, and the modifier follows the Levinson rule for species with essential REE.
Note: The original type material has Y>Ce and is a Ce-rich chukhrovite-(Y)
(for discussion see https://www.mindat.org/mesg-577618.html). A neotype was defined by Mauro et al. (2025).
