Eudialyte

Cyclosilicate

Eudialyte, whose name derives from the Greek phrase Εὖ διάλυτος eu dialytos , meaning "well decomposable", is a somewhat rare, nine member ring cyclosilicate , which forms in alkaline rocks, such as nepheline. Its name alludes to its ready solubility in acid.

Eudialyte was first described in 1819 for an occurrence in nepheline syenite of the Ilimaussaq intrusive complex
