About Nosean
Karl Wilhelm Nose
Formula:
Na8(Al6Si6O24)(SO4) · H2O
Ideal Nosean has no Ca and all the S is oxidized to sulfate.
Colour:
Colorless, white, gray, gray-brown, blue, black
Lustre:
Vitreous
Hardness:
5½
Specific Gravity:
2.3 - 2.4
Crystal System:
Isometric
Member of:
Name:
Named by Martin H. Klaproth in honor of Karl Wilhelm Nose (18 November 1753, Braunschweig, Germany - 22 June 1835, Endenich near Bonn, Germany), a physician in Augsburg, 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.
Also classed as a feldspathoid.
