Dear friends:
Please
no more name of rock unless we cannot communicate without such a name.
I
would call the rock in question Opx amphibolite or Amp granulite and presume it
belongs to the Hbl granulite facies (or subfacies). . Metabasite in the epidote
blueschist facies (or subfacies) may be epidote blueschist or greenschist. It
is too covetous (is this a proper word?) to hope single name can represent
protolith, mineral assemblage and facies it belongs to.
