	Astrophyllite - Definition, explanation
		Astrophyllite is a very rare, brown to golden yellow hydrous potassium iron titanium silicate mineral.
		Found in cavities and fissures in unusual felsic igneous rocks, astrophyllite is associated with feldspar, mica, titanite, zircon, nepheline and aegirine.
		Astrophyllite is found in a few scarce, remote localities: Mont-Saint-Hilaire, Quebec, Canada; Pikes Peak, Colorado, USA; Narsarsuk and Kangerdluarsuk, Greenland; Brevig, Norway; and the Kola Peninsula, Russia.

		It is this crystal habit that gives astrophyllite its name; from the Greek words astron meaning "star" and phyllon meaning "leaf." Its high, submetallic lustre and dark colour contrast sharply with the light coloured (felsic) matrix the mineral is regularly found within.

		Nb-dominant kupletskite and, similarly, Zr-rich astrophyllite in the altered pegmatites are thought to be extremely late-stage phases, the result of remobilization of Nb and Zr by postmagmatic deuteric fluids.
		True astrophyllite is rare at MSH and is restricted to the sodalite syenite, pegmatitic miarolitic cavities, and a metasomatic unit associated with the hornfels.
		Astrophyllite is thought to be the result of crystallization from late-stage residual or metasomatic fluids.
