About Mangano-ferri-eckermannite
Shukusuke Kozu
Formula:
{Na}{Na2}{Mn2+4Fe3+}Si8O22(OH)2
The Eckermannite minerals are sodium amphiboles defined with A(Na+K+2Ca)> 0.5 apfu and 0.5 apfu < C(Al+Fe3++2Ti) < 1.5 apfu with Al>Fe3+ in the C3+ position. Normally if Fe3+ > Al, these minerals are named with an arvfedsonite root-name. For some reason, it has been decided to introduce the name ferri-eckermannite for this mineral.

Name:
The mineral with this chemical composition was described by Nambu et al. (1969) and named kôzulite for Shukusuke Kôzu (1880-1955), Japanese mineralogist, Tohoku University. The original publications was without proper structure refinement, which was not prepared until 2010 by Barkley et al. (2010).
Kôzulite was included in both the 1978 and 1997 amphibole nomenclature, but was discredited as a root name in the 2012 amphibole nomenclature, where the mineral was renamed mangano-ferri-eckermannite.
Kôzulite was included in both the 1978 and 1997 amphibole nomenclature, but was discredited as a root name in the 2012 amphibole nomenclature, where the mineral was renamed mangano-ferri-eckermannite.
Note: The status of mangano-ferri-eckermannite as a valid mineral species and successor of ‘kôzulite’ is questioned by Kasatkin et al. (2023).
