Evidências geomorfológicas de alguns processos responsáveis pela evolução quaternária do canhão de Setúbal

Abstract

Key words: submarine canyon, Gouf, Geomorphology, tectonic, submarine hydrographic net, batimelric depression, erosive processes. The deep submarine valley near Setúbal Ihat conneclS the continental platform to the Tagus Abyssal Plain is a submarine canyon of the type commonly knows as Gouf. ln this article we try to show the tectonic influence in its formation and in the installation of its submarine hydrographic net. Some indirect evidences of erosive processes responsible for the formation of typical submarine forms of canyons are analysed based in the interpretation of the batimetric map. Finally, we try to give a brief idea of the evolution of this canyon based on the knowledge Ihat is accepted for the area where he belongs.
