Structures in metamorphic rock - #3
Tight folds in migmatitic gneiss -- the field of view is about one metre wide. In this complexly deformed rock, the limbs of the whitish folds have been severed by shearing along the metamorphic layering. (For a lengthy explanation of this rock type, see my previous "Structures in metamorphic rock - #2" photo, in my "Geology in building stone" album.)
This smooth clean polished surface is from some ornamental building stone in downtown Calgary.
