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.
