  • The existence of a tectonic window in the northern area of the Aramo-Morcin anticlinorium is demonstrated. The thrust sheet is formed of an early Devonian detritical and calcareous succesion called the Raneces Group, whereas the autochton is made up by a Carboniferous sucession of shales and sandstones belonging to the Riosa Unit (upper Westphalian). The occurrence of such a window can be interpreted as the result of superposed folding related to front and lateral ramps and allows the interpretation for this area of a shallower basal thrust plane than the one previously proposed
