Ideal Nosean has no Ca and all the S is oxidized to sulfate.
System:IsometricColour:Colorless, white, gray, ...
Hardness:
Member of:Sodalite Group
Name:
Named by Martin H. Klaproth in honor of Karl Wilhelm Nose [November 18, 1753 Braunsweig, Germany - June 22, 1835 Endenich near Bonn, Germany), physician in Augsberg, Elberfeld, and Bonn. Nose was also a chemist and mineralogist who wrote extensively on chemical, mineralogical, and geological research.


Sodalite Group. The two sodalite cages in Nosean's unit cell contain Na4SO4 and Na4H2O.

May be confused with pale-coloured haüyne. Bright blue nosean is easily mistaken for Lazurite
