	Olympus Microscopy Resource Center: Polarized Light Microscopy Gallery - Cordierite Anthophyllite Skarn
		Skarns are a type of rock that develops in the vicinity of igneous intrusions when sizable amounts of aluminum, silicon, iron, and magnesium are introduced to limestone or other sedimentary rocks chiefly composed of carbonates.
		Among the minerals that are often associated with cordierite is anthophyllite, a member of the amphibole group.
		Commonly found in metamorphic and metasomatic rocks, anthophyllite derives its name from the Latin word for “clove,” a reference to its characteristic clove-brown coloration.

		Under appropriate pressure-temperature conditions (approximately 3–4 kbar and 550°–700°C), colinearity in the composition of cordierite, anthophyllite and cummingtonite, in the presence of quartz, results in the degenerate univariant reaction anthophyllite = cordierite + cummingtonite.
		Mantling of cummingtonite by anthophyllite probably was the result of cooling from peak conditions of metamorphism.
