(Université de Lille) ; Álvaro Blasco, José Javier (Instituto de Geociencias (CSIC-Universidad Complutense de Madrid)) ; Casas Tuset, Josep Maria (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà)
The Ediacaran-Lower Ordovician successions exposed in the Eastern Pyrenees are updated and revised based on recent U-Pb zircon radiometric ages, intertonguing relationships of carbonate-dominated strata, and onlapping patterns marking the top of volcano-sedimentary complexes. [...]

17 p, 7.4 MB Deformation pattern around the Conejera fault blocks (Asturian Basin, North Iberian Margin) / Martínez Granado, Pablo (Universitat de Barcelona. Departament de Ciències de la Terra i de l'Oceà) ; Tavani, Stefano (Università degli Studi di Napoli Federico II. Dipartimento di Scienze della Terra, dell'Ambiente e delle Risorse) ; Carrera, N. (Universitat de Barcelona. Departament de Ciències de la Terra i de l'Oceà) ; Muñoz, Josep Antón (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà)
The Asturian Basin is located on the coastline of the North Iberian Margin. This basin is dissected by long-lived E-, NE- and NW-striking faults that delineate a series of extensional fault blocks that became shortened during the Upper Cretaceous to Cenozoic Alpine convergence. [...]

16 p, 9.6 MB The extent of penetrative Pyrenean deformation in the Ebro foreland Basin : magnetic fabric data from the eastern sector / Parés Casanova, Josep María (Centro Nacional de Investigación sobre la Evolución Humana-CENIEH) ; Anastasio, David (Lehigh University. Earth and Environmental Sciences Department)
We studied Cenozoic sedimentary rocks in the NE Ebro foreland Basin using the Anisotropy of Magnetic Susceptibility (AMS) as a proxy for grain preferred orientation. Our new data, in combination with existing results, reveal that penetrative strain by layer-parallel shortening extends well beyond the Pyrenean thrust-wedge front into the Ebro foreland Basin, challenging the concept of the location of "deformation front" in the Southern Pyrenees. [...]

20 p, 15.8 MB Weld kinematics of syn-rift salt during basement-involved extension and subsequent inversion : results from analog models / Roma, M. (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Ferer, O, (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; McClay, K.R. (Fault Dynamics Research Group, Earth Sciences Department) ; Muñoz, Josep Antón (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Roca i Abella, Eduard (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Gratacós, O. (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Cabello López, Patricia (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà)
Scaled analog models based on extensional basins with synrift salt show how basement topography exerts a control factor on weld kinematics during the extension and inversion phases. In the case of basement-involved extension, syn-rift salt thickness differences may lead to variable degrees of extensional decoupling between basement topography and overburden, which in turn have a strong impact on the development of salt structures.

16 p, 3.9 MB Minorca, an exotic Balearic island (western Mediterranean) / Sàbat i Montserrat, Francesc (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Gelabert Ferrer, Bernardí (Universitat de les Illes Balears. Departament de Ciències de la Terra) ; Rodriguez-Perea, Antonio (Universitat de les Illes Balears. Departament de Biologia)
Despite forming part of the Balearic group of islands, Minorca differs stratigraphically and structurally from Majorca and Ibiza: i) Paleozoic rocks are abundant in Minorca but are very scarce in Majorca and are absent in Ibiza. [...]

12 p, 2.8 MB Structure of an intraplate fold-and-thrust belt : The Iberian Chain. A synthesis. / Guimerà Rosso, Joan J. (Universitat de Barcelona. Departament de Geodinàmica i Geofísica)
The Iberian Chain is a complex intraplate fold-and-thrust belt resulting from the convergence between the Eurasian, Iberian and African plates during the late Eocene to the Miocene. The main trend of its contractionalstructures is NW-SE, but E-W, NE-SW and N-S-trending structures are also present. [...]

22 p, 8.7 MB The structure of the South-Central-Pyrenean fold and thrust belt as constrained by subsurface dat / Muñoz, Josep Antón (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Mencos, Joana (Universitat de Girona. Departament de Ciències Ambientals) ; Roca i Abella, Eduard (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Gratacós Torrà, Òscar (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Ferrer García, José Oriol (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Fernández, O.
The interpretation of the available seismic lines of the South-Central-Pyrenean fold and thrust belt, conveniently tied with the exploration wells, define the main structural features of this realm of the Pyrenees. [...]

16 p, 9.3 MB First evidence of paleoearthquakes along the Carboneras Fault Zone (SE Iberian Peninsula) : Los Trances site / Masana, Eulàlia (Universitat de Barcelona. Departament Dinàmica de la Terra i de l'Oceà) ; Moreno, X. (Universitat de Barcelona. Departament Dinàmica de la Terra i de l'Oceà) ; Gràcia, E. (Institut de Ciències del Mar) ; Pallàs i Serra, Raimon (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Ortuño Candela, Maria (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; López Escudero, Robert (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Gómez-Novell, Octavi (Universitat de Barcelona.

(Czech Academy of Sciences. Institute of Rock Structure and Mechanics) ; Khazaradze, Giorgi (Universidad de Granada. Departamento de Geodinámica)
Seismogenic faults that have not produced historical large earthquakes remain unnoticed and, thus, are dangerously left out from seismic hazard analyses. The seismogenic nature of the Carboneras Fault Zone, a left-lateral strikeslip fault in the Eastern Betic Shear Zone (southeastern Spain), has not been fully explored to date in spite of having a morphological expression equivalent to the Alhama de Murcia Fault, a seismogenic fault in the same tectonic system.

20 p, 5.6 MB Active fault control in the distribution of Elevated Low Relief Topography in the Central-Western Pyrenees / Ortuño Candela, Maria (Universitat de Barcelona. Departament de Dinàmica de la Terra i de l'Oceà) ; Viaplanas-Muzas, Marc (Consejo Superior de Investigaciones Científicas. Instituto Jaime Almera (Barcelona))
The activity of normal faults in the Central-Western Pyrenees is mainly detected by the disruption of paleic landforms surviving to Plio-Quaternary incision: the remnants of a Low-Relief Topography (LRT) that probably originated asynchronically during the Oligocene and Miocene. [...]
