Anthrophyllite, magnesium iron silicate hydroxide is a common component of some metamorphic and metasomatic rocks. Its name comes from the Latin word for clove and is an allusion to its typical and distinct clove-brown color, though it has green varieties. Anthophyllite is metamorphic and is found in magnesium rich igneous or dolomitic sedimentary rocks.
It is useful in teaching that bonds, restrictions, and constraints placed upon a person are self-imposed and easily discarded. Anthrophyllite allows the heart to decide what is important.
