/əˈstrɒfᵻlʌɪt/, U.S.

/əˈstrɑfəˌlaɪt/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: astro- comb. form, -phyllite comb. form.

Etymology: < astro- comb. form + -phyllite comb. form, after German Astrophyllit (T. Scheerer 1854, in Berg- u. Hüttenmännische Zeitung 13 240). N.E.D. (1885) indicates the stress as astroˈphyllite.

Mineralogy.

A yellow to brownish-red mineral typically occurring as thin, elongated crystals, often in star-shaped aggregates.Astrophyllite is a silicate of iron, titanium, manganese, and other metals, (K,Na)₃(Fe,Mn)₇Ti₂Si₈O₂₄(O,OH)₇. Crystal system: triclinic.
