Microphotographs of the lithotypes sampled in the Fium’Orbo valley: metagranitoid (CMD37) with a parallel and b crossed Nicols. The S1–S2 mylonitic foliation (normal to the long side of the pictures) is the anisotropy marked by the phyllosilicates wrapping the Qz and Fsp porphyroclasts. In the pictures related to the epidote-bearing metagabbro (CMD50E), with c parallel and d crossed Nicols, the S1–S2 mylonitic foliation (parallel to the long side of the pictures) is marked by the Chl layers alternated to those made of Cpx and Fsp. Large Cpx crystal are partially replaced by Ep and Chl
