Resumen de Evolución neogena de la cuenca baja del Tambre
José Luis Pagés Valcarlos, Juan Ramón Vidal Romaní
The present paper study the evolution of the lower part of the Tambre Basin during the Neogene. The basin, the fluvial network and a group of features are analyzed, such as the asymmetry of the net, the entrenchement, steps, etc, that are present in the Tambre and also frequent in other fluvial systems of Galicia. It is settled down that the current configuration of the fluvial network has been reached after a complex system of captures, with inversion of the drainage directions. Such evolution is not presented like an anecdotic circunstance in the layout of the river but rather it is considered a remarkable example of the fluvial processes that have contributed to the modeling of the present relief of Western Galicia.
