Dear Piotr There is some degree of transpression at these latitudes, both offshore Brazil and in West Africa. It would be good to know the magnitude of this uplift, and the geometry of the structures you observed. Some structures, if striking in particular directions, can be significantly reactivated - particularly in the (often exhumed) proximal margin. Best wishes Tiago _____________________________ Tiago M.
