Formula:
{Na}{Mg2}{Mg5}(AlSi7O22)(OH)2
Formula redefined in the 2012 nomenclature.
Colour:
Clove-brown to dark brown, grey to white, green.
Lustre:
Vitreous
Hardness:
5½ - 6
Crystal System:
Orthorhombic
Name:
Named as the sodium-bearing and magnesium-dominant orthoamphibole resembling anthophyllite.
In order to better distinguish between amphibole end-member member compositions, the CNMNC has decided to rename sodic-anthophyllite. The name is not yet (Nov 2012) decided.
