Characterization of submarine slides in the upper and middle slope of the Gulf of Cádiz (SW Iberian Peninsula)

Abstract

The identification and characterization of a series of complex landslides have been carried out using Topographic Parametric Sounder (TOPAS) very high resolution profiles, obtained during the INDEMARES/CHICA1011 and ARSA0313 cruises, along the upper and middle slope of the eastern Gulf of Cádiz continental margin. These landslides constitute a large area of the Upper Quaternary sedimentary deposits in these physiographic domains and are related to active tectonic and diapiric structures along the Upper Quaternary as well as sea-level fall events. The identification of the stratigraphic units has allowed us to obtain the relative age of these gravitational landslides emplacement during the Upper Quaternary.Versión del edito
