Fábricas magnéticas en materiales sin-diapíricos del encajante (N cuenca Vasco-Cantábrica)
This work shows the results obtained after the analysis of the Anisotropy of Magnetic Susceptibility (AMS) of 29 sites sampled on Aptian-Albian marls, marly limestones, fine sandstones and lutites. The study area is located ...
Westerlies migrations and volcanic records over the past 4,000 years from the Azores lacustrine sequences. Exploring correlations and impacts on Western Europe
The Azores region plays a crucial role as a pathway for precipitation fronts traversing the North Atlantic from west to east, driven by the prevailing westerly winds. Variations in the strength of the Azores High affect ...
Deep crustal electromagnetic structure of Bhuj earthquake region (India) and its implications
The existence of fluids and partial melt in the lower crust of the seismically active Kutch rift basin (on the western continental margin of India) owing to underplating has been proposed in previous geological and geophysical ...
Neogene to recent contraction and basin inversion along the Nubia-Iberia boundary in SW Iberia
The SW of Iberia is currently undergoing compression related to the convergence between Nubia and Iberia. Multiple compressive structures, and their related seismic activity, have been documented along the diffuse Nubia-Iberia ...
A 500 kyr record of global sea level oscillations in the Gulf of Lion, Mediterranean Sea: new insights into MIS 3 sea level variability
Borehole PRGL1-4 drilled in the upper slope of the Gulf of Lion provides an exceptional record to investigate the impact of late Pleistocene orbitally-driven glacio-eustatic sea-level oscillations on the sedimentary ...
Distribución geográfica y cronoestratigráfica de Palliolum (Lissochlamys) excisum (Mollusca, Pectinidae) en España
Palliolum (L.) excisum (Bronn) se encuentra en España en tres áreas: Cordillera Litoral (Cordillera Costero-Catalana), región de Alicante (Cordilleras Béticas) y Depresión del Guadalquivir. En las dos primeras tiene una ...
First paleoseismological results in the epicentral area of the sixteenth century Ameca earthquake, Jalisco - México
The Trans-Mexican Volcanic Belt (TMVB) is a calc-alkaline volcanic arc cut by different active crustal fault systems that have originated several destructive historical earthquakes. Located in the central part of Mexico ...
Mid- to Late-Holocene Mediterranean climate variability: Contribution of multi-proxy and multi-sequence comparison using wavelet analysis in the northwestern Mediterranean basin
Forcings and mechanisms underlying Holocene climate variability still remain poorly. This work review already published paleoclimatic time series and proposes an alternative way to compare them using spectral analysis. ...
New Mediterranean speleothem records for glacial Terminations IV and III
Speleothem archives spanning the glacial terminations IV and III (TIV and TIII) are particularly scarce in the western Mediterranean region. This study presents unprecedented geochemical records measured on a speleothem ...
Growth of collisional orogens from small and cold to large and hot - inferences from geodynamic models
It is well documented that the interplay between crustal thickening and surface processes determines growth of continent‐continent collision orogens from small and cold to large and hot. Additionally, studies have demonstrated ...
A User‐Friendly Workbook to Facilitate Rapid and Accurate Rare Earth Element Analyses by ICP‐MS for Multispiked Samples
The rare earth elements (REEs) are widely used as geochemical tracers in the earth, planetary, and ocean sciences. Inductively coupled plasma‐mass spectrometry (ICP‐MS) has become the method of choice to analyze REE ...
Evolución tectónica y sedimentaria durante el Priaboniense superior-Mioceno inferior, en el frente de cabalgamiento de las Sierras Marginales occidentales
Se han distinguido cuatro complejos sedimentarios del Eoceno superior-Mioceno inferior en los depósitos continentales del margen norte de la cuenca del Ebro...
Flux and composition of settling particles across the continental margin of the Gulf of Lion: the role of dense shelf water cascading
Settling particles were collected using sediment traps deployed along three transects in the Lacaze-Duthiers and Cap de Creus canyons and the adjacent southern open slope from October 2005 to October 2006. The settling ...
Improving the modeling of geomagnetically induced currents in Spain
Vulnerability assessments of the risk posed by geomagnetically induced currents (GICs) to power transmission grids benefit from accurate knowledge of the geomagnetic field variations at each node of the grid, the Earth's ...
La evolución geodinámica de la Cuenca Catalano-Balear y áreas adyacentes desde el Mesozoico hasta la actualidad
Las deformaciones contractivas y extensivas cenozoicas se concentran en los márgenes de las antiguas cubetas mesozoicas, de manera que la mayora de las fallas cenozoicas son el resultado de la reactivación de las fallas ...
A revised definition for copal and its significance for palaeontological and Anthropocene biodiversity‑loss studies
The early fossilization steps of natural resins and associated terminology are a subject of constant debate. Copal and resin are archives of palaeontological and historical information, and their study is critical to the ...
Forward seismic modeling as a guide improving detailed seismic interpretation of deltaic systems: Example of the Eocene Sobrarbe delta outcrop (South-Pyrenean foreland basin, Spain), as a reference to the analogous subsurface Albian Cenomanian Torok-Nanushuk Delta of the Colville Basin (NPRA, USA)
A forward seismic model of the Middle Eocene Sobrarbe delta outcrop (South-Pyrenees, Spain) has been made to investigate its seismic signature. The Sobrarbe delta complex corresponds to a syntectonic sedimentary wedge ...
New perspectives in studying active faults in metropolitan France: the 'Active faults France' (FACT/ATS) research axis from the Resif-Epos consortium
Mainland France is part of a plate interior with a strong structural heritage, undergoing a low rate of deformation, where destructive earthquakes can nevertheless occur. In this paper, we emphasize that the knowledge of ...
Correlación bioestratigráfica entre las sucesiones miocénicas marinas de Sant Pau d'0rdal y Sant Llorenc d'Hortons (Depresión del Vallès - Penedès, Barcelona)
En base a los moluscos fósiles y a criterios sedimentológicos, se realiza una reconstrucción paleoambiental del sector de Sant Pau d'Ordal y de La Pedrera de Sant Llorenq d'Hortons y se deduce la equivalencia lateral de ...
The North Pyrenean front and related foreland basin along the Bay of Biscay: constrains from the MARCONI deep seismic reflection survey
Profile interpretation of MARCONI seismic profiles show that two domains exist in the Bay of Biscay with a different Pyrenean and north-foreland structure: the eastern, Basque-Parentis and the western, Cantabrian domains. ...
