Hi Bernardo,
My first guess would be that this has more to do with a hydrogarnet component rather than deformation. I have seen anisotropic garnets in the Franciscan (Ward Creek). I never probed them, but was told that they were Mn rich. I believe these were from zone III?

Subject: [geo-metamorphism] Optically anisotropic garnet
Dear all,
we have found a highly deformed blueschist showing optically anisotropic garnet, not yet probed but presumably a Fe-Mg(-Mn) solution.
A first, quick search for similar occurrences didn't bring results so I'd greatly appreciate your feedback, and to receive references of studies that might help us in the interpretation of this behaviour.
Thank you very much in advance!
Regards,
Bernardo
