Manganocummingtonite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
☐{Mn22+}{Mg5}(Si8O22)(OH)2
System:
Monoclinic
Colour:
nd
Lustre:
Vitreous
Hardness:
5 - 6
Name:
Originally named mangan-cummingtonite in 1966 by Hugo Strunz in allusion to its composition, containing MANGANese, and its relationship to Cummingtonite.

In order to better distinguish between amphibole end-member member compositions, the CNMNC has decided to rename manganocummingtonite. The name is not yet (Nov 2012) decided.

Classification of Manganocummingtonite

Approved
9.DE.05

9 : SILICATES (Germanates)
D : Inosilicates
E : Inosilicates with 2-periodic double chains, Si4O11; Clinoamphiboles
