The photo above showing the well studied unconformity of Antromero, in Asturias province (northen Spain), was taken this past August. An unconformity is a buried erosion surface. Note the differences between the structure of the cliff on the lefthand side and righthand side of the picture. Erosion and deposition of comparatively young (Cretacious) rocks from the Hercinic Mountain Range are poorly matched with older, more deformed Devonian deposits.
