Ferri-sadanagaite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
{Na}{Ca2}{Mg3Fe3+2}(Al3Si5O22)(OH)2
The sadanagaite group minerals are defined as with 0,5 < A(Na+K+ 2Ca) where Na or K is dominant, and with 1,5 < C(Al+Fe3++2Ti), where Al or Fe3+ are dominant. The W position may contain (OH),F or Cl.

Ferri-sadanagaite is defined with
A position: Na dominant
C2+ position: Mg dominant
C3+ position: Fe dominant
W position: (OH) dominant.
