The Merluza Graben: How a failed spreading center influenced margin structure, and salt deposition and tectonics in the Santos Basin, Brazil
The relative timing between crustal extension and salt deposition can vary spatially along passive margin salt basins as continents unzip, or as the locus of extension shifts toward the embryonic ocean spreading center. ...
Nuevas aportaciones al conocimiento de las formaciones pliocénicas de l'Alt Empordà, Girona
En esta nota se da una lista de los Moluscos fósiles hallados en las arcillas azules de la base de los niveles de Sant Mori-Sant Miquel de Fluva y otra de la a fauna contenida en los niveles amarillentos superiores. La ...
Uppermost mantle seismic velocity and anisotropy in the Euro-Mediterranean region from Pn and Sn tomography
In the last 10-15 years, the number of high quality seismic stations monitoring the Euro-Mediterranean region has increased significantly, allowing a corresponding improve in structural constraints. We present here new ...
A review of the granite concept through time
Granitic rocks are ubiquitous worldwide in ancient and active tectonic settings, representing powerful sources of information about the Earth's past and present geodynamic behaviour. Numerous recent milestones fostering ...
Straight-jawed lacewing larvae (Neuroptera) from Lower Cretaceous Spanish amber, with an account on the known amber diversity of neuropterid immatures.
Three larval neuropterans (Insecta: Neuropterida) with straight mandibulomaxillary stylets are described from Lower Cretaceous (late Albian, ~105 Ma) Spanish amber: a third-instar beaded lacewing (Berothidae) from the ...
El Mioceno marino entre las playas de l'Arrabassada y El Miracle (Tarragona): aspectos paleontológicos e implicaciones sedimentológicas
En el sector comprendido entre las playas de L'Arrabassada y El Miracle (Tarragona) han sido reconocidas las dos secuencias deposicionales (Garraf y Tarragona) presentes en el área del Camp de Tarragona. El limite entre ...
Expected geomagnetically induced currents in the Spanish islands power transmission grids.
<p>The aim of this study is to evaluate the geomagnetically induced current (GIC) hazard in the power networks of the Canary and Balearic archipelagos. This is done in order to strictly complete the detailed assessment at ...
GIS-based debris flow source and runout susceptibility assessment from DEM data - a case study in NW Nicaragua
In October 1998, Hurricane Mitch triggered numerous landslides (mainly debris flows) in Honduras and Nicaragua, resulting in a high death toll and in considerable damage to property. The potential application of relatively ...
Reply to Elias et al.: Multiproxy evidence of widespread landscape disturbance in multiple Azorean lakes before the Portuguese arrival
Despite the multidisciplinary and comprehensive approach taken in ref. 1, we acknowledge that there are still open questions that require further research. We emphasize that our study relies on multiple records that show ...
Analisis litosismico y estructura sedimentaria de la plataforma interna al Norte del Delta del Ebro (Sector de Vandellos)
El análisis sísmico de perfiles de alta resolución del tipo ((uniboom)), realizados en la plataforma interna al N del Delta del Ebro, permite definir las unidades sísmicas y establecer la estructura sedimentaria del ...
Rapid response of benthic deep-sea microbes (viruses and prokaryotes) to an intense dense shelf water cascading event in a submarine canyon of the NW Mediterranean Sea
A major dense shelf water cascading (DSWC) event occurred in 2005 downward the Cap de Creus Canyon (Gulf of Lion, NW Mediterranean Sea), which caused a significant change in environmental parameters and biological components. ...
El Dr. Lluís Via Boada, una vida fecunda
El Dr. Lluís Via Boada, nació en Vilafranca del Penedes en octubre de 1910, y empezó sus estudios eclesiásticos en el Seminario de Barcelona en setiembre de 1925.
Micromammalian faunas from the middle miocene (middle Aragonian) of the Tudela formation (Ebro Basin, Spain)
Two new fossil micromammal localities of Middle Miocene age (Pico del Fraile 2, PF2 and Sancho Abarca 5, SA5) from the Tudela Formation (northeastern Ebro Basin) are described. PF2 contains rodents and insectivores of ...
Fault interpretation in seismic reflection data: an experiment analysing the impact of conceptual model anchoring and vertical exaggeration
The use of conceptual models is essential in the in- terpretation of reflection seismic data. It allows interpreters to make geological sense of seismic data, which carries inherent uncertainty. However, conceptual models ...
Slope instability along the northeastern Iberian and Balearic continental margins
This paper gathers the available information on submarine landslides identified in the northeastern Iberian continental margin and presents new data on both already known landslides and new, previously unknown ones. The ...
Assessment of the Restoration of the Remolar Dune System (Viladecans, Barcelona): The Resilience of a Coastal Dune System
The Remolar beach-dune system (700 m long and more than 100 m wide, 070N direction) borders a campground that was closed (2003), due to the Barcelona airport expansion. In order to recover and restore the dune ecosystem, ...
Applicability of magnetic fabrics in rocks associated with the emplacement of salt structures (the Bicorb-Quesa and Navarrés salt walls, Prebetics, SE Spain)
This work assesses the applicability of the analysis of the anisotropy of magnetic susceptibility (AMS) to rocks associated with salt structures.Magnetic fabrics from16 sites sampled on Upper Triassic clays (Keuper facies) ...
Mineralización estratiforme de Pb-Zn-Cu en el Paleozoico de Bassegoda (Pirineo Oriental)
Al Sur del pico de Bassegoda existe una mineralización estratiforme de galena, esfalerita y pirita con calcopirita y arsenopirita, en forma de diseminaciones y lentejones masivos, situadas dentro de un tramo de 10 metros ...
Las formaciones cuaternarias del delta del Llobregat
E11 esta nota explico de forma muy resumida las principales hipótesis y conclusiones expuestas en la memoria que, sobre el mismo tema y con el mismo título, he realizado como tesis doctoral. Se estudian las características ...
Structure des grands bassins glaciaires dans le nord de la péninsule ibérique: comparaison entre les vallées d'Andorre (Pyrénées orientales), du Gállego (Pyrénées centrales) et du Trueba (Chaîne Cantabrique).
Les grandes vallées glaciaires de la Péninsule Ibérique sont situées dans la chaîne pyrénéo-cantabrique, principalement dans le bassin de l'Èbre. Ainsi, les vallées d'Andorre, de la Noguera Pallaresa et de la haute vallée ...
