Perhaps a useful piece for the discussion of the meaning of metamorphic
facies is Turner's 1968 definition:
"A metamorphic facies is a set of metamorphic mineral assemblages,
repeatedly associated in space and time, such that there is a constant and
therefore predictable relation between mineral composition and chemical
composition"
