Formula:
{K}{Ca2}{Mg3Al2}(Al3Si5O22)Cl2
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.
Potassic-chloro-sadanagaite is defined with
A position: K dominant
C2+ position: Mg dominant
C3+ position: Al dominant
W position: Cl dominant.
Potassic-chloro-sadanagaite is defined with
A position: K dominant
C2+ position: Mg dominant
C3+ position: Al dominant
W position: Cl dominant.
One of the analysis published by Kullerud et Erambert (1999) is showed by Locock (2014) to be a Ferro-chloro-sadanagaite.
