The richterite group minerals are defined as sodium-calcium amphiboles with 0,5 apfu < A(Na+K+ 2Ca) where Na or K is dominant, and with C(Al+Fe3++2Ti)<0,5 apfu. The W position may contain (OH),F or Cl.

Richterite is defined with
A position: Na dominant
C position: Mg dominant
W position: (OH) dominant.

Member of:Richterite Root Name Group > Sodium-Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup
Name:Named in 1865 by Johann Friedrich August Breithaupt in honor of Hieronymus Theodor Richter [November 21, 1824 Dresden, Germany – September 25, 1898 Freiberg, Saxony, Germany], professor of chemistry at Freiberg University of Mining and Technology. He was the co-discoverer of indium.
