A check of my bookshelf shows that Frank Spear (1993, Min Soc Am Monograph 1,p. 14-18) already implemented both of my suggestions re SCMR's Paper #3 (i.e., he dropped pyroxene-hornfels and sanidinite facies, and he opted for "blueschist facies" instead of "glaucophane-schist facies"). Way to go Frank!!! Cheers, Dugald
