Backarc evolution from rifting to mature spreading: The Bransfileld and North Fiji Basins (NW Antarctica and SW Pacific)
(Sociedad Geológica de España, 1996)Five areas, the Eastern and Central Bransfield Basins off the Antarctic Peninsula, and the Tripartite, Central Spreading and South Pandora Ridges of the North Fiji Basin, have been studied using swath-bathymetry and ... -
Comportamiento hidráulico y sedimentario del río Ebro, entre Tortosa y Amposta (Tarragona, España)
(Sociedad Geológica de España, 1990)The segment studied in the Lower Ebro River is 13 km long and it marks the end of fluvial-dominated environments preceeding the deltaic environments (fluvio-deltaic, fluviomarine and river mouth) fully developed down ... -
La Cuenca Central de Bransfield (NW de la Peninsula Antàrtica): primeros resultados de la campaña GEBRA'93
(Sociedad Geológica de España, 1994)The GEBRA '93 (Geological Evolution of the Bransfield Basin) survey was carried out in December 1993 in the Bransfield Strait (NW Antarctic Peninsula) and adjacent areas, onboard BIO Hespérides. The geophysical data ... -
Dinámica de los canales submarinos del talud y el glacis continentales del Ebro (Mediterráneo-noroccidental) a partir de imágenes acústicas de alta resolución
(Sociedad Geológica de España, 1996)A comprehensive data set of the seafloor relief and superficial sedimentary cover on the Ebro progradational continental slope, NW Mediterranean Sea, reveals that its Late Quaternary building results from complex ... -
Distribución y composición elemental de la materia particulada en suspensión en el Mar Catalano-Balear
(Sociedad Geológica de España, 1996)The spatial distribution at sufface (-5m) and bottom (2-5m a.s.f.) /levels of the concentration and elemental composition of the suspended particulate matter show that the main trends result from the interaction between ... -
Estratigrafía molecular aplicada a la reconstrucción de las temperaturas y las salinidades superficiales del Mar de Alborán desde la última glaciación
(Sociedad Geológica de España, 1996)Sea Surface Temperalures (SST) and salinity anomalies (AS) of the Western Alboran Sea have been evaluated since the Last Glacial maximum (18 ky Bp) using the Uk37 index. This molecular index is based on the determination ... -
Estratigrafía Sísmica comparada de los márgenes de la Cuenca Central de Bransfield, la Península Antàrtica y el Mar de Ross (Antártida Occidental)
(Sociedad Geológica de España, 1996)The glacial periods are recorded in the sedimentary cover of the Antarctic margins as progading units and erosive surfaces. The comparison of three margins of the Western Antarctica allows valuation of the regional ... -
Evolución sedimentaria de un nuevo sistema turbidftico en el Atlántico sur: el sistema turbidftico de Agadir
(Sociedad Geológica de España, 1996)The Agadir turbidite system is located on the Morocco continental margin and the Agadir Basin (South Atlantic), and extends from 200 m to 4300 m water depth. Its establishement seems to have occured during the Oligocene, ... -
La depresión periférica y el lomo contourítico de Menorca: evidencias de la actividad de corrientes de fondo al N del Talud Balear
(Sociedad Geológica de España, 1996)A peripheral depression with a sediment drift on its N flank develop N and E of Minorca Island. Both are interpreted to result from the activity of bottom currents circulating parallel to the base of the island slope since ... -
Mass physical, granulometric and mineralogical Characterisation of the glaciomarine sediments of the Bransfield Basin ( NW Antarctic Peninsula)
(Sociedad Geológica de España, 1996)The textural analysis of two gravity cores reveals that the sediments in the Central and Eastern Bransfield subbasins are mainly clayey silts with some coarser levels of sandy silts. While a turbidity origin can be attributed ... -
Quantification of neogene and quaternary sediment input to the Madeira Abyssal Plain
(Sociedad Geológica de España, 1996)Cruises Tydeman 80, Tyro 82 and ODP Leg 157 provided 7000 km of single-channel seismic profiles and three d rillin g sites w ith a to ta l o f 11 58 m o f core in the Madeira Abyssal Plain. Merging o f the lithological ... -
Sedimentación cuaternaria en la plataforma y el talud continentales del Golfo de León (Mediterráneo nor-occidental). 1- parte: Estratigrafía sísmica de baja y alta resolución
(Sociedad Geológica de España, 1996)This paper is focused on the seismic stratigraphy of the Culf of Lions continental shelf and slope, off the present Rhone Delta. A low resolution multichannel seismic profile allows to divide the Plio-Quaternary section ... -
Sedimentación cuaternaria en la plataforma y el talud continentales del Golfo de León (Mediterráneo nor-occidental). 2- parte: Orden de ciclicidad de las secuencias sísmicas en alta resolución y cronoestratigrafía isotópica
(Sociedad Geológica de España, 1996)This study tries to establish the chronostratigraphy of the Late Quaternary high-resolution seismic units off the present Rhône Delta. Previous works have associated the deposition of these seismic units with 5th order ... -
The submarine "El Golfo" debris avalanche and the Canary debris flow, West Hierro lsland:The last major slides in the Canary archipelago
(Sociedad Geológica de España, 1996)Swath bathymetry and geophysical data of the island of Hierro show that the western flank of the island is affected, at least, by two major catastrophic slope failures. One of the two, called the El Golfo debris avalanche, ... -
Variations in the Mediterranean thermohaline circulation during the Last Glacial/Interglacial transition (20 Ka PB), based on a dinocyst record of the Alboran Sea
(Sociedad Geológica de España, 1996)The dinoflagellate cyst assemblages in a core from the Western Alboran Sea, in the upwelling domain off Malaga, show a record of marine environmental change for the Late Glacial and Holocene periods. The dinocysts are good ...
