• Resumen

  • This work is a summary of the study carried out in the preparation of the Spanish Continental Margin Geomorphological Map at 1:1.000.000 scale, that nowadays is being elaborated by the Geological Survey of Spain, Marine Geology Division. The principal objective of this study is to mapthe main continental margin and abyssal plain morphological features, and the related active processes, on the basis of several scientific publications and local studies from different authors andnew data obtained from recent oceanographic cruises. In this map, three processes, that influencein the relief generation, have been established: tectonic, erosive and depositional processes. Inaddition, two more groups have also been differentiated: polygenetic (unknown origin) and gravitational processes. The mapping of these elements has been carried out upon a simplified bathymetric base provided by the Marine Hydrographic Institute and upon a synthetic sea bottom lithological cartography.
