Name:Parvomanganoedenite 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. Parvomanganoedenite 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 edenite according to the 2012 amphibole nomenclature.
