Potassic-hastingsite

This page is currently not sponsored. Click here to sponsor this page.
The hastingsite-group minerals are defined with 0.5 < A(Na+K+2Ca)<1.5 where Na or K is dominant and with the C position occupied by Mg or Fe2+ as dominant divalent ions and 0.5 < C(Al+Fe3+ +2Ti) < 1.5 where Fe3+ is dominant. W may contain (OH),F or Cl.

Potassic-hastingsite is defined with:

A position: K dominant
C position: Fe dominant divalent ion
W position: (OH) dominant
