Influence of de acute accent collement-cover thickness variations in fold-and-thrust belts: Insights from centrifuge analog modeling
Centrifuge analog modeling incorporating thickness variations of décollement and overlying sedimentary cover is used to study thrust-wedge evolution on salt-detached contractional systems involving tapered sedimentary ...
Modelos 3D de análogos de reservorios sedimentarios: Aplicación al sistema de abanico costero eoceno de Sant Llorenç del Munt (Cuenca del Ebro)
3D reservoir characterizations of analogues based on outcrop studies provide geological information that can be used for reducing uncertainty in subsurface reservoir modelling to predict interwell areas. 3D reservoir-scale ...
Fósiles urbanos: un patrimonio paleontológico que pasa inadvertido.
Desde las primeras construcciones hasta nuestros días, diferentes tipos de rocas (sedimentarias, ígneaso metamórficas) han sido explotadas principalmente en función de si presentan o no unas cualidades óptimas para tal ...
Stretching and contraction of extensional basins with pre-rift salt: a numerical modelling approach
We present a series of 2D thermo-mechanical numerical experiments of thick-skinned crustal extension including a pre-rift salt horizon and subsequent thin-, thick-skinned, or mixed styles of convergence accompanied by ...
Paleoecology of Easter Island: evidence and uncertainties
The existence of palm-dominated forests covering the island since the last glaciation and the recent deforestation by humans are paradigmatic in Easter Island's paleoecological reconstructions. The timing and mode of the ...
Geology of the Eastern Prebetic Zone at the Jumilla region (SE Iberia)
This article presents a geological map and cross-sections at 1:50,000 scale covering an area of 609 km2 of the Eastern Prebetic Zone (SE Iberia). The structure of the studied area is characterized by an NW-directed ...
New magnetotelluric data trough the boundary between the Ossa Morena and Centroiberian Zones
The south-western part of the Iberian Peninsula, including the southern branch of the Iberian Massif, has recently been the subject of several magnetotelluric (MT) studies. This area is made up of three different tectonic ...
ENSO and solar activity signals from oxygen isotopes in diatom silica during Lateglacial-Holocene transition in Central Andes (18ºS).
The Late Glacial-Holocene transition from the Lago Chungará sedimentary record in northern Chilean Altiplano (18ºS) is made up of laminated sediments composed of light and dark pluriannual couplets of diatomaceous ooze. ...
Detection of faecal bacteria and antibiotic resistance genes in biofilms attached to plastics from human-impacted coastal areas
Plastics have been proposed as vectors of bacteria as they act as a substrate for biofilms. In this study, we evaluated the abundance of faecal and marine bacteria and antibiotic resistance genes (ARGs) from biofilms adhered ...
Paleomagnetic and paleoenvironmental implications of magnetofossil occurrences in late Miocene marine sediments from the Guadalquivir Basin, SW Spain.
Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than have been previously reported, their significance for paleomagnetic and paleoenvironmental studies is not ...
Measurement report: Spatial variability of northern Iberian rainfall stable isotope values - investigating atmospheric controls on daily and monthly timescales
For the first time, this article presents a large dataset of precipitation isotopic measurements (δ18Op and δ2Hp) sampled every day or 2 d from seven sites on a west-to-east transect across northern Spain for 2010-2017. ...
Tragèdia als Apenins:La prevenció és indispensable
L'esdeveniment catastròfic esdevingut als Abruzzo, al centre d'Itàlia, on una gran allau ha destruït un hotel provocant diverses víctimes, ens ha de fer reflexionar una vegada més sobre com i on edifiquem. Falten encara ...
3D modelling of grain size distribution in Quaternary deltaic deposits (Llobregat Delta, NE Spain).
The Llobregat delta constitutes a Pliocene-Quaternary sequence recording progradation. An 8 meter-thick, delta-plain succession temporarily accessible in the subaerial delta plain was sub-divided into four units (A to D), ...
Structure of the mantle beneath the Alboran Basin from Magnetotelluric Soundings
We present results of marine MT acquisition in the Alboran sea that also incorporates previously acquired land MT from southern Spain into our analysis. The marine data show complex MT response functions with strong ...
Necrophagy by insects in Oculundentavis and other lizard body fossils preserved in Cretaceous amber.
When a vertebrate carcass begins its decay in terrestrial environments, a succession of different necrophagous arthropod species, mainly insects, are attracted. Trophic aspects of the Mesozoic environments are of great ...
Icnología de vertebrados de las facies Buntsandstein de Mallorca
Se describen, por primera vez en Mallorca, hasta cinco tipos diferentes de icnitas y pistas de vertebrados continentales dentro de las facies cuarzoareniticas y limosas rojas de la facies Buntsandstein del Triásico inferior
La geografía física d'Andorra des del punt de vista geològic i geomorfològic
Es proposa en aquest apartat una visió general de l'evolució deis concixements sobre la geografia física del Principat, centrant-se en l'aspecte geologic i geomorfologic. L'obJectíu és que el lector pugui tenir un a ...
Study of the Avalanche Dynamics by means of Seismic Methods, Image Processing Techniques and Numerical Models
Seismic signals of avalanches, related video images and numerical models were compared to improve the characterization of avalanche phenomena. Seismic data and video images from two artificially released avalanches were ...
Carboneras Fault seismic characterization: new paleoseismic and GPS data integration
Carboneras Fault is located on the highest seismicity zone of the Iberian Peninsula. Despite the low instrumental and historical seismicity associated with the fault, it has been defined as seismogenic (7,6 0,3 max Mw) ...
The last deglaciation in the SW Iberian margin: changes in the Atlantic surface and Mediterranean bottom waters
The transition from the Last Glacial Maximum to the Holocene interglacial period is marked by abrupt global changes in which ocean thermohaline circulation, ice sheets and atmosphere interacted. Mediterranean overturning ...
