Odinite (original) (raw)

A valid IMA mineral species

Formula:

(Fe,Mg,Al,Fe,Ti,Mn)2.4((Si,Al)2O5)(OH)4

Colour:

Silky green to dark green

Crystal System:

Monoclinic

Name:

For French clay mineralogist Gilles Serge Odin (May 31, 1942 in Arcis sur Aube, France - ?), University P. and M. Curie, Paris, France. He did the initial work on this mineral.

Kaolinite-Serpentine Group.

Note: odinite can also refer to a basaltic dyke rock with primarily anorthite (labradorite) and some augite in a groundmass of fine grained hornblende and minor quartz.
