In the the Sant Corneli-Bóixols anticline, a syn-growth unconformity divides and de-couples a lower overturned pre-growth unit from an upper syn-growth one. Pre-growth strata and the unconformity underwent syn-folding shearing, even where they are mutually perpendicular. Different and coeval shear senses occurring at different structural positions indicate that regardless of its orientation, layering in the pre- and syn-growth sequences of the anticline was continuously sheared.
