Abstract

Simposio sobre el Margen Ibérico Atlántico (9º. 2018. Coimbra, Portugal), More than 70 mud volcanoes (MVs) are identified along the continental margin of the Gulf of Cadiz,,although only a few have been thoroughly sampled and direct observed. This work is a contribution to the knowledge of the Gulf of Cadiz MVs Madrid and El Cid, located in the continental slope known as Western Moroccan Field over 1300 m water depth. On Madrid MV extensive crusts and mud breccia were observed. Nevertheless in El Cid MV, the rocky fragments are of smaller size and mud breccia has not been sampled/observed on the surface. In both MVs, coral reefs colonizing rocky fragments and covering seafloor of metric size have been observed., Departamento de Ciencias de la Tierrra, Universidad de Cádiz, España, Centro Oceanográfico de Málaga, Instituto Español de Oceanografía, España, Centro oceanográfico de Cádiz, Instituto Español de Oceanografía, España, Instituto Geológico y Minero de España, España, Estrutura de Missão para a Extensão da Plataforma Continental, Portugal

Abstract

Simposio sobre el Margen Ibérico Atlántico (9º. 2018. Coimbra, Portugal), This work represents an approach to the more suitable proxy’s in order to identify and characterize mass movement deposits and the respective deformation. As case study was selected the Portimão Bank, a submarine E–W elongated structural high with prominent slide scars, located offshore southern Portugal in the Gulf of Cadiz. Our results show that: i) The Portimão Bank is characterized by a series of important on-going landslides; ii) The sedimentary column retrieved from piston core is replicated; iii) magnetic fabrics are able to identify a segment with approximately 90 cm that accommodated the deformation associated with the replication of the sedimentary column. Important to emphasize that such deformation goes unnoticed by mesoscopic analysis., Instituto Dom Luiz, Portugal, Instituto Superior de Engenharia de Lisboa, Portugal, Estrutura de Missão para a Extensão da Plataforma Continental, Portugal, Instituto Português do Mar e da Atmosfera, Portugal, Instituto de Ciencias del Mar, España, Centro Oceanográfico de Málaga, Instituto Español de Oceanografía, España, Instituto Geológico y Minero de España, España

Abstract

Several giant circular-elliptical depressions have been analyzed in the continental margins off North Iberian (NICM) and West Africa (WACM) by means of multibeam bathymetric data and seismic reflection profiles. Their long axes vary between 2 and 4.7 km, the width axis between 2 and 3.5 km and their reliefs between 40 and 370 m. Depressions are slightly elliptical with eccentricity index between 0.73 and 0.9. They are partially filled by sediments producing different V and U bathymetric crosssections. The Burato Ergap depression in the NICM and the Twin Pools depressions in the WACM occur overlying diapirs. Burato Ergap depression is originated as a collapse structure related to underlying diapiric mobility. Twin Pools depressions seem to represent seafloor reworking by the action of deep sea bottom currents interacting with and adjacent diapiric ridge on the seafloor
