Well, the next step is to drop the blueschist facies because blueschists
sometimes occur in the greenschist facies.
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
