Gadolinite-(Y)

This page is currently not sponsored. Click here to sponsor this page.
Johan Gadolin
Formula:
Y2Fe2+Be2Si2O10
Often slightly radioactive due to minor U and/or Th contents; therefore often metamict.
System:
Monoclinic
Colour:
Black, greenish-black, ...
Lustre:
Vitreous, Greasy
Hardness:
6½ - 7
Name:
Named after J. Gadolin (1760-1852), discoverer of yttrium and the "-(Y)" suffix due to the dominance of yttrium in the composition.
Gadolinite-Datolite Group. The yttrium analogue of gadolinite-(Ce).
Difficult to distinguish from hingganite-(Y).
