Paleogene kinematics of the central Catalan Coastal Ranges: temporal constraints from magneto-chronology and provenance analysis in synorogenic deposits in the SE margin of the Ebro Basin (NE Spain)
The precise determination of the tectonic deformation timing such as thrust emplacement has always been a challenge for understanding the evolution of fold-and-thrust belts. In the Catalan Coastal Ranges, this issue has ...
Caracterización 3-D de un canal turbidítico en el margen continental del Ebro (Mediterráneo Occidental)
El presente documento recoge los principales resultados científicos del Capítulo 5 de la Tesis Doctoral del autor titulada “Modelización y visualización 3-D en Geociencias Marinas”, presentada en la Universitat de Barcelona ...
Coastal raptors and raiders: New bird tracks in the Pleistocene of SW Iberian Peninsula
Avian traces occurring in Pleistocene aeolianite and beach deposits are rare and relatively poorly known, despite being good paleoenvironmental indicators. Passeriform and raptorial birds are especially rare in the track ...
New Workflow for Bridging the Gap Between Geology Knowledge and Society: The Example of the VIGEOCULT Project and the Orígens Geopark. South‑Central Pyrenees
The effective dissemination of geological content in an engaging and easy-to-follow manner is challenging, especially because in most situations the general public has a limited geological background. This is particularly ...
Calibrating lower‑middle Miocene mammal faunas and unravelling climate change during the Miocene Climate Optimum: the Bardenas Reales de Navarra record (Ebro basin, NE Iberian Peninsula).
The chronology of lower Miocene Iberian small mammal faunas is still poorly constrained given the scarcity of well dated sedimentary successions including small mammal fossil localities. Such scarcity has prevented also ...
Coralgal buildup in a mixed carbonate-siliciclastic succession of the upper Eocene Sant Martí Xic Formation (Orís, Vic, SE Ebro Basin, Spain)
Coralgal buildups from the mixed carbonate siliciclastic succession of the upper Eocene Sant Martí Xic Formation (Orís, Vic, SE Ebro Basin, Spain) were studied. During the upper Eocene, the sedimentation in the Orís area ...
Reframing jellyfish perception from “enemies” to “helpers” through Ocean Literacy
Despite covering three-quarters of Earth’s surface and comprising 99% of its habitable space, the ocean remains underrepresented in formal education, contributing to widespread Ocean Literacy (OL) deficits. Jellyfish – ...
An alternative experimental configuration to generate wrench zone above a viscous layer
Analogue modelling of wrench tectonics typically utilizes a rigid basement with a velocity discontinuity under a brittle or brittle-viscous cover, such as in Riedel experiments, which confines fault localization in the ...
Icnofacies de <em>Glossifungites</em> en el Mioceno del Mas de les Pardinetes (Oeste de Alcoy)
Se estudian las trazas fósiles del Mioceno del Mas de les Pardinetes (oeste de Alcoy). Los icnotaxones identificados: Glossifungites saxicava Łomnicki, 1886, Spongeliomorpha iberica Saporta, 1887 y Gastrochaenolites ornatus ...
Zipper tectonics in the Tyrrhenian-Apennines system: linking rift inheritance with thrusting, back-arc extension and crustal delamination
We review geological and geophysical data across the Tyrrhenian back-arc basin–central Apennines fold and thrust belt system and incorporate them into a crustal-scale balanced cross-section. The section allows us to derive ...
Ichnogeny and bivalve bioerosion: examples from shell and wood substrates
The ichnospecies Gastrochaneolites dijugus Kelly and Bromley 1984 and Teredolites longissimus Kelly and Bromley 1984, attributed to the boring activity of gastrochaenoid and pholadid bivalves, are described respectively ...
An Ichnofossil-lagerstätte from the miocene vilanova basin (ne spain): taphonomic and paleoecologic insights related to bioerosion structures.
A new ichnofossil-Lagerst¨atte from the Miocene Vilanova Basin (NE Spain) is described. It is characterized by bioerosion structures that are exceptionally preserved as positive casts, many associated with internal and ...
<em>Estrellichnus jacaensis</em> from the Eocene Jaca Basin of NE Spain: new locality and new ethological interpretation
New occurrences of Estrellichnus jacaensis in the deep‐marine turbidite deposits of the Eocene Hecho Group (Fiscal, Huesca, NE Spain) are described. Most of them include specimens preserved as 'urban fossils' located in ...
¿Cuántas emisiones evitaríamos si dejásemos de viajar en avión?
Según datos de The International Council on Clean Transportation (ICCT), las emisiones globales de CO₂ del transporte aéreo comercial representaron en 2018 algo más del 2,4 % de las emisiones mundiales debidas a combustibles ...
A refugium for charophytes during the maximum post-Palaeozoic sea-level highstand in the Turonian of Tarragona (Catalonia, Spain)
During the Cenomanian–Turonian interval, Europe was largely submerged under a shallow tropical sea within the Cretaceous Tethyan Archipelago, limiting non-marine lacustrine habitats to a few coastal lakes on the islands. ...
Cementación temprana por calcita en un frente deltaico deescala métrica: cambios en la calidad del reservorio
La arenisca de Roda se corresponde con un delta del Eoceno inferior situado en el margen norte de la cuenca de Graus-Tremp en el antepaís surpirenaico. Se estudia la distribución de los diferentes productos diagenéticos ...
New insights on the crustal deformation in the Eastern Betics from densified GNSS data
The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within ...
Formation and growth of diapirs in contractional settings: the Mediano anticline and Clamosa diapir case study (Southern Pyrenees)
At the northwestern termination of the South Pyrenean Central Salient, thrust imbrication, detachment folding and diapirism are structurally and genetically related. The La Fueba imbricate system has been folded by the ...
Increased Ecosystem Productivity Boosts Methane Production in Arctic Lake Sediments
Global estimates of methane (CH4) emissions from lakes to the atmosphere rely on understanding CH4 processes at the sediment‐water interface (SWI). However, in the Arctic, the variability, magnitude, and environmental ...
The non-marine Lower Cretaceous of El Montsec thrust-sheet (South-Central Pyrenees)
The aim of this study is resolving uncertainties on the lithostratigraphy and chronostratigraphy of the non-marine Lower Cretaceous of El Montsec thrust sheet, which contains the most developed record of such facies in the ...
