An integrated approach to define new plays in mature oil basins: the example from the Middle Magdalena Valley basin (Colombia)
An integrated approach to detect new areas of potential interest associated with stratigraphic traps in mature basins is presented. The study was carried out in the Middle Magdalena Valley basin, Colombia. The workflow ...
Fracture analog of the sub-Andean Devonian of southern Bolivia: Lidar applied to Abra Del Condor, in G. Zamora, K. R. McClay, and V. A. Ramos, eds., Petroleum basins and hydrocarbon potential of the Andes of Peru and Bolivia
Tight fractured sandstones of the Devonian Huamampampa Formation are associated with large gas discoveries in the sub-Andean fold-and-thrust belt of southern Bolivia. A LIDAR-based fracture characterization of the Abra del ...
Holocene changes in deep-water circulation of the Western Mediterranean Basin, links to North Atlantic climate variability
preliminary results from multicores recovered in the Minorca sediment drift, south of the Western Mediterranean Deep Water formation area, reveal changes in deep-water circulation during the last 2500 yr. Records of ...
Lo único que no sabemos es cuándo
El 12 de febrero de 1835,durante su visita a la ciudad portuaria de Valdivia, Charles Darwin fue testigo del terremoto de Concepción, de magnitud 8,5, que describió así: se ha notado el más violento terremoto que se recuerda ...
From geology to seismic parameters in slow faults: new challenges
Paleoseismology allows the characterization of seismogenic faults in high strain rates regions but also in areas with moderate rates of deformation like the Iberian Peninsula. There, an important amount of paleoseismic ...
Estudio geológico del Eoceno prepirenaico del Ripollés oriental
En este trabajo se presentan los principales resultados obtenidos en el estudio geológico del Eoceno plegado del Ripolés oriental. Se da un corte interpretativo de la cuenca de sedimentación as como la edad y génesis de ...
Palaeobiology of tanaidaceans (Crustacea: Peracarida) from Cretaceous ambers: extending the scarce fossil record of a diverse peracarid group.
Diverse assemblages of tanaidacean peracarid crustaceans from western Tethyan continental deposits suggest that the group was relatively common in or around ancient resin-producing forests. Here we report the results of ...
Mediterranean thermohaline circulation variability from the last deglaciation associated with changes in the eastern Mediterranean water outflow
The Eastern Mediterranean Sourced Water (EMSW) outflow through the Strait of Sicily and together with the Western Mediterranean Deep Water (WMDW) contribute with different proportion to the Mediterranean outflow waters ...
The Basque - Cantabrian Pyrenees: report of data analysis
This contribution presents the analysis of a data set that was put together in the PhD thesis of Jordi Miró which is part of the OROGEN Project. The Basque - Cantabrian Pyrenees, that are the focus of this report, have ...
Icnogenia: cómo identificar el paso a paso en la interacción organismo-sustrato
Las galerías fosilizadas de un crustáceo del Mioceno han permitido proponer un nuevo concepto científico y distinguir claramente entre el desarrollo de un organismo (ontogenia) y el de las trazas que deja (icnogenia) su ...
Mating and aggregative behaviors among basal hexapods in the Early Cretaceous
Among the many challenges in paleobiology is the inference and reconstruction of behaviors that rarely, if ever, leave a physical trace on the environment that is suitable for fossilization. Of particular significance are ...
An updated biostratigraphy for the late Aragonian and the Vallesian of the Vallès-Penedès Basin (Catalonia)
The Vallès-Penedès Basin (Catalonia, Spain) is a classical area for the study of the Miocene land mammal faunas and includes one of the densest and most continuous records in Eurasia. Furthermore, it is the type area for ...
Deep-sea bioluminescence blooms after dense water formation at the ocean surface
The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting of a 2.5-year long record of light ...
Structural control of inherited salt structures during inversion of a domino basement-fault system from an analogue modelling approach
The geometries of inverted rift systems are different depending on a large variety of factors that include, among others, the presence of decoupling layers, the thickness of the pre- and syn-extension successions, or ...
Forward numerical modelling constraining environmental parameters (Aptian carbonate system, E Iberia)
The facies distribution in time and space of sedimentary successions is controlled by a complex interplay between physical, chemical and biological processes, which are nowadays difficult to construe from the geological ...
Modeling the interaction between presalt seamounts and gravitational failure in salt-bearing passive margins: The Messinian case in the northwestern Mediterranean Basin
The northwest Mediterranean Basin includes a thick Messinian salt sequence composed of three evaporitic units. From these, the intermediate unit, which is dominantly composed of halite, acted as a gravitational detachment ...
A systematic review on microplastic pollution in water, sediments, and organisms from 50 coastal lagoons across the globe
Coastal lagoons are transitional environments between continental and marine aquatic systems. Globally, coastal lagoons are of great ecological and socioeconomic importance as providers of valuable ecosystem services. ...
New ichnological data from the lower Paleozoic of the Central Pyrenees: presence of <em>Arthrophycus brongniartii</em> (Harlan, 1832) in the Upper Ordovician Cava Formation
The ichnogenus Arthrophycus, characteristic of Ordovician-Silurian sedimentary rocks, is described by the first time in the Pyrenees. This ichnogenus is located in fine-grained sandstones of the upper part of the Cava ...
On the origin of the North Pacific arcs
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean. According to our model, the ...
Nota preliminar sobre las turbiditas eocenas de los alrededores de Ripoll (Prov. de Gerona)
En este trabajo se presentan algunos resultados sobre las características sedimentológicas de las turbiditas eocenas de Ripoll, considerándose igualmente su posición y significado dentro de la cuenca de sedimentación prepirenaica.
