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.

katophorite is defined with

A position: Na dominant
C2+ position: Mg dominant
C3+ position: Al dominant
W position: (OH) dominant
System:MonoclinicColour:Dark greenish-black to ...
Lustre:VitreousHardness:5
Member of:Katophorite Group > Sodium-Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup
Name:Katophorite was defined as the katophorite group mineral with Fe and Al as the dominant elements in the C position in the 1978 and 1997 amphibole nomenclature. The katophorite group was redefined in the 2012 amphibole nomenclature, renaming the Fe2+ and Al dominant member of the group ferro-katophorite.

The name katophorite is now used for the Mg and Al dominant member of the group, which was named magnesiokatophorite in the 1978 and 1997 amphibole nomenclature.
This page provides mineralogical data about Katophorite.
