About Spreustein
Formula:
Na2Al2Si3O10 · 2H2O
Name:
Named by A.G. Werner in 1811 and derived from the German word "spreu" = awn, due to its colour and appearance.
A variety of Natrolite
A fine-grained natrolite replacing a hydrothermally altered sodalite and/or nepheline. Not uncommon in some nepheline-syenite pegmatites.
Compare also hydronephelite.
