About Ferro-katophoriteHide

The katophorite group minerals are sodium-calcium amphiboles defined with A(Na+K+2Ca)> 0.5 apfu and 0.5 apfu < C(Al+Fe3++2Ti) < 1.5 apfu.

Ferro-katophorite is defined with

A position: Na dominant
C2+ position: Fe dominant
C3+ position: Al dominant
W position: (OH) dominant
From the Greek for "carrying down," in allusion to its volcanic origin

This mineral was defined as katophorite in the 1978 and 1997 amphibole nomenclatures. The katophorite group minerals was redefined in the 2012 amphibole nomenclature and the Fe 2+ and Al dominant katophorite group mineral is now named ferro-katophorite.
This page provides mineralogical data about Ferro-katophorite.
