About Katophorite Root Name GroupHide

Formula:

A(CaNa)(C²⁺₄C³⁺)(AlSi₇O₂₂)W₂

The katophorite 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.

The individual minerals are defined by the dominant elements in the A, C and the W positions. The most common dominant elements in the various positions are:
A position: Na or K dominant
C²⁺ position: Mg or Fe²⁺ dominant
C³⁺ position: Al or Fe³⁺ dominant
W position: (OH) or F dominant

Member of:

Sodium-Calcium Amphibole Subgroup > w(OH,F,Cl)-dominant Amphibole Group > Amphibole Supergroup
