Abstract Recent models support the view that Pyrenees were formed after inversion of a previously highly extended continental crust included exhumed upper mantle rocks. Mantle rocks remain near to surface compression and mountain building, covered by latest Cretaceous Paleogene sequences. 3‐D lithospheric‐scale gravity demands presence high‐density body placed within in order justify observed anomalies. Exhumed mantle, having ~50 km maximum width, continuously extends beneath...
Bouguer anomaly maps are powerful cartographic tools used mainly by geoscientists and natural resources' companies (oil, mining, etc.) since they reflect rock density distribution at different depths, allowing the identification of tectonic features. At upper crustal levels, can help, for instance, in characterizing possible ore deposits, ground water reservoirs, petroleum resources, CO2 storage sites sedimentary basins; deeper levels help to further refine seismic velocity models or other...
Abstract Critical gravity and magnetic data suggest the presence of a continuous zigzag exhumed mantle body inside attenuated crust north Iberia continental margin. We propose that this greatly conditioned structural domains Cantabrian–Pyrenean fold-and-thrust belt during their evolution from hyperextension in Early Cretaceous times to shortening inversion Cenozoic. This may be seen as new line for cross-section construction balancing, because previous cross-sections do not incorporate...
The Eastern Pyrenees mark the transition of Pyrenean Range towards Mediterranean Sea. Because this specific structural location, crustal geometries in area register a significant along-strike change, mainly resulting from overprint Neogene extension on Late Cretaceous-Cenozoic orogenic structure.  Along-strike changes are marked by lateral termination Iberian lower crust subduction and progressive eastwards thinning both European crusts. Although Moho depth studies abundant agree...
A P wave seismic velocity model has been obtained for the Central Iberian Zone, largest continental fragment of Variscan Belt.The spatially dense, high-resolution, wide-angle reflection experiment, ALCUDIA-WA, was acquired in 2012 across central Iberia, aiming to constrain lithospheric structure and resolve physical properties crust upper mantle.The transect, ~310 km long, crossed Zone from its suture with Ossa-Morena southern limit System mountain range.The energy generated by five shots...
Abstract. Sediments provide valuable information for geologists and geophysicists whenever they strive to understand, reproduce, the geological evolution, lithology, rock properties, seismic response, geohazards of a region. The analysis sedimentary sequences is thus useful interpretation depositional environments, sea-level change, climate recognition sediments' source areas. By integrating data into geophysical modeling, such interpretations are improved in terms their accuracy...
Abstract. The major goal of this work is to provide insight into the structural and geological anatomy Pyrenees based on magnetic anomalies inferred lineaments from Earth Magnetic Anomaly Grid 2 arcmin resolution (EMAG2v2) data. We focus providing qualitative semi-quantitative evidence signature mountain range domains structures. integration reduced-to-the-pole processed maps, as well Bouguer anomaly map with data, has proved be significantly useful in order shed light main sources....
Abstract The South Pyrenean triangle zone represents the southernmost front of Pyrenees at its central portion deforming Upper Eocene‐Miocene Ebro Basin deposits. Two main structures characterize western termination, Barbastro anticline and San Román backthrust, which detached on Formation (and lateral equivalents), an Eocene‐Lower Oligocene syntectonic evaporite‐rich formation that acted as a multidetachment unit. Northward, south directed thrust unit (i.e., Gavarnie‐Sierras sheet) along...
A 2D modeling of geoid/quasigeoid data across the Pyrenees is consistent with electromagnetic images Pyrenean lithospheric structure, showing a subducted Iberian lower crust. Using new magnetotelluric acquired through orogen, 3D electrical conductivity model structure obtained. The most outstanding feature presence high zone at crustal depths along orogen in contact between and European plates. integration various geophysical parameters suggests that simplest reasonable mechanism to explain...
The dimensions, the geographical position and complex geological history of Iberian Peninsula makes it a unique singular target to study its crustal upper mantle structure geodynamical evolution using geophysical methods. lithospheric beneath Iberia has been investigated since 1970's deep multichannel seismic reflection refraction/wide-angle profiling. Gravimetric magnetic data were acquired following deployment permanent temporary stations, mostly during 1990's. Beginning in late 1990's,...
Near‐vertical incidence reflection seismic data acquired in the Tagil Volcanic Arc (Middle Urals) show upper crust to be highly reflective. Two intersecting lines located near ongoing ∼5400 m deep SG4 borehole that main reflectivity strikes approximately N‐S and dips ∼35°–55° east. Prominent reflections intercept at ∼1000, ∼1500, 2800–2900, ∼3400, between ∼4000 5400 m, which correspond intervals of low velocity/low density/low resistivity. The surface projections these lie parallel strike...
The lithospheric structure across the Møre Margin has been studied by integrating regional elevation, gravity, geoid and heat-flow data together with available seismic geological data. Our results show that Moho depth varies from 42 km beneath Caledonides to 20–15 basin 13–16 in oceanic domain. lithosphere thins a step-like manner 160 inland 60–80 A comparison Vøring reveals both margins have similar crustal structures. Major dissimilarities are: (1) volume of underplating ocean–continent...
