Allanite-(Y)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
{CaY}{Al2Fe2+}(Si2O7)(SiO4)O(OH)
Often slightly radioactive due to minor U and/or Th contents; therefore often metamict.
Colour:
Black
Lustre:
Sub-Vitreous, Resinous, Waxy, Greasy
Hardness:
5½ - 6½
Specific Gravity:
3.5 - 4.2
Crystal System:
Monoclinic
Name:
Re-named, but not described, in 1966 by Alfred Abraham Levinson using what is now called the Levinson Rule whereby REE-dominant minerals are named by their root mineral name olus chemical suffixes. Allanite was named in 1810 by Thomas Thomson for Thomas Allan (1777-1833), Scottish mineralogist, who first observed "allanite". The -(Y) suffix was later added by Levinson (1966) to designate the Y-dominant member of the allanite group.
Allanite Subgroup of the Epidote Group.
Black usually massive mineral. Resinous when fresh, but frequently dulled by hydrothermal alteration or weathering.
