About Sadanagaite Root NameHide

Formula:
A (Ca2)(Z2+3Z3+2)(Si5Al3O22)(OH,F,Cl)2
The sadanagaite root name minerals are defined as minerals in the calcium amphibole subgroup with 0,5 < A(Na+K+ 2Ca) where Na or K is dominant, and with 1,5 < Z(Al+Fe3++2Ti), where Al or Fe3+ are dominant. The W position may contain (OH),F or Cl.

The individual minerals are defined by their dominant element in the A, Z2+ (= IMA C2+) and W position.

In mindat.org we avoid using variables with the same symbol as elements and deviate from the IMA nomenclaure in that we use X rather than B, Z rather than C and (OH,F,Cl,O) rather than W.
Crystal System:
Monoclinic
Name:
Named for Ryoichi Sadanaga (b. 1920), Professor Emeritus of the University of Tokyo.
The first sadanagaite mineral was published (IMA1980-027) by Shimazaki et al. (1984). Since then, the group has been redefined twice, both on the 1997 and 2012 amphibole report. It is therefore necessary to verify all references for sadanagaite-group minerals by checking the chemical composition for correct naming of the referenced mineral.

The naming history for each species is discussed under the individual minerals.
