Parvo-manganotremolite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
☐{CaMn2+}{Mg5}(Si8O22)(OH)2
System:
Monoclinic
Name:
Parvo-mangano-edenite was published as a new mineral species by Oberti et. al. in 2006, but was discredited by the new amphibole nomenclature in 2012.

The 2012 nomenclaturen of amphiboles classifies the amphiboles based on the dominant element in each position, unless otherwise required to balance the formula. Parvomanganotremolite defined with (CaMn2+)in the B position is consequently discredited. The empirical formula published by Oberti et.al.(2006) qualifies this material as a Mn-rich tremolite according to the 2012 amphibole nomenclature.

Classification of Parvo-manganotremolite

Discredited 2012

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