Aerinite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ca5.1Na0.5)(Fe3+,Al,Fe2+,Mg)4(Al,Mg)6[HSi12O36(OH)12][(CO3)1.2(H2O)12]
System:
Monoclinic
Colour:
blue to blue-green
Hardness:

Name:
From the Greek "aerinos," for sky-blue, alluding to its color.
A rare, chemically complex carbonate-bearing silicate.

A closely related, darker blue mineral (intergrown with Fe3+-rich aerinite) is described by Rius et al. (2009).
