Sodic-ferro-anthophyllite (Natrium-Ferro-Anthophyllit)

Collectors Summary

Hardness (Mohs) 5 - 6
Crystal System orthorhombisch, Pnma

Additional information / Summary

Name empfohlen vom Amphibol Subkomitee (1997) für ein theorethischen Na-Fe2+Endglied der Ampibol-Serie. Um besser zwischen Amphibol Endglieder Zusammensetzungen zu unterscheiden, hat die CNMNC beschlossen, Natron-Ferro-Anthophyllit umzubenennen. Der Name ist noch nicht (Nov 2012) veröffentlicht.
