Is this your sole?

Amphibolite -- not garnet bearing, but certainly showing the kind of deformation that happens when one is stuck between an ophiolite and a continental margin.
Note: FIRST the rock was formed from the metamorphism of something like an old convenient basalt hanging around. THEN all the banding was folded and stretched and crumpled like hell. What does this say about the emplacement process, hus, huh, huh?
The width of the photo corresponds to ~5 cm of real rock.
