Base Characterization
-
The Portas de Ródão (Ródão doors) are the expression in the relief of the transposition of a quartzic ridge by the Tagus river. The narrowing of Tagus valley at this location is due to the strong resistance of quartzite to erosion, functioning as natural dams. This form of relief and other geological data suggest the existence of a pre-Tagus that had run on a surface topographical above the current level of the ridge.
