About Allanite-(Nd)Hide

Thomas Allan
Formula:
{CaNd}{Al2Fe2+}(Si2O7)(SiO4)O(OH)
Colour:
Dark brown to black
Crystal System:
Monoclinic
Name:
Named in 2012 by Radek Škoda, Jan Cempírek, Jan Filip, Milan Novák, František Veselovský and Radim Čtvrtlík for being neodymium-dominant and its relationship to the allanite-series minerals. The group name is in honor of Thomas Allan (1777, Edinburgh, Scotland - 1833, Morpeth, Northumberland, England), Scottish banker and mineralogist.
