So you are talking hardness of the metamorphic rock eh? An educated guess is all you have Croc?....LOL Hows about you provide a link to any published results with respect to MPa? An educated guess won't cut it I'm afraid.
Some of the more important factors you should be considering are that of the graphite itself, such as crystallinity.
Blitz I have made no false claims whatsoever. I have offered up my opinions based on the evidence before me. Neither you or Croc have provided a definitive answer as to the MPa of the host rock, even though you want to pose those very questions yourself. Hypocrisy personified!
