Linked detachment folds, thrust faults, and salt diapirs: Observations and analog models
Contractional deformation in salt-bearing rifted- and convergent-margin settings often involves diapirism. Diapirs may predate the onset of shortening, such that they exert a pronounced influence on how contractional strain ...
The crustal structure of the Cantabrian Mountains revealed by new magnetotelluric soundings
The upper crustal structure of the central Cantabrian Mountains consists of a block of Variscan basement uplifted over the Duero basin as a consequence of a southward displacement along a major thrust during the convergence ...
Lacustrine Systems in Convergent Margins
From the late seventies to the present day, lacustrine sedimentology and lacustrine-related basin analysis have developed from a near-marginal aca- demic curiosity into a new ground-breaking multidisciplinary body of ...
The influence of subaquatic springs in lacustrine sedimentation: Origin and paleoenvironmental significance of homogenites in karstic Lake Banyoles (NE Spain)
Banyoles (42°08′N, 2°45′E) is the largest and deepest lake of karstic<br>tectonic origin in the Iberian Peninsula. The lake comprises two basins and six sub-circularly shaped sub-basins fed by subaquatic springs. Periods ...
Ploughing the deep sea floor
Bottom trawling is a non-selective commercial fishing technique whereby heavy nets and gear are pulled along the sea floor. The direct impact of this technique on fish populations1,2 and benthic communities3,4 has received ...
Combining surface exposure dating and burial dating from paired cosmogenic depth profiles. Example of El Límite alluvial fan in Huércal-Overa basin (SE Iberia)
Cosmogenic nuclide depth-profiles are used to calculate the age of landforms, the rates at which erosion has affected them since their formation and, in case of deposits, the paleo-erosion rate in the source area. However, ...
DInSAR coseismic deformation of the May 2011 Mw 5.1 Lorca earthquake, (Southern Spain)
The coseismic superficial deformation at the region of Lorca (Murcia, southeastern Spain) due to the Mw 5.1 earthquake on 11 May 2011 was characterized by a multidisciplinary team, integrating information from DInSAR, GPS ...
Evaluation of a snow avalanche possibly triggered by a local earthquake at Vallée de la Sionne, Switzerland
Snow avalanches are moving sources of infrasonic and seismic energy. They can be triggered by many different mechanisms that include the shaking produced by earthquakes. The forces induced by an earthquake can cause an ...
Basement-involved reactivation in foreland fold and thrust belts: the Alpine-Carpathian Junction (Austria)
The Late Eocene to Early Miocene Alpine-Carpathian fold-and-thrust belt (FTB) lies in the transition between the Eastern Alps and the Western Carpathians, southeast of the Bohemian crystalline massif. Our study shows the ...
Communication between scientists of different language, culture and field
Scientific communication will be considered from many perspectives. My aim is to discuss here some aspects of the communication between scientists of different language, culture and field. On the one hand, there is the ...
El margen continental catalán (II): Evolución tectonosedimentaria y registro paleobiológico
Los presentes segundo a cuarto números junto con el primero del volumen 29 de Acta Geologica Hispanica, forman parte de un conjunto temático centrado en 'El margen continental catalán'. Estos números especiales tienen por ...
La Formación de Bellmunt (Unidad del Cadí, Pirineo Oriental): aportaciones bioestratigráficas de los sistemas lacustres y palustres asociados
La Formación de Bellmunt es una unidad aluvial de carácter sinorogénico relacionada con el emplaiamiento de 1os mantos pirenaicos.En suzonainferior-media intercala numerosos tramos lacustres y palustres que contienen una ...
Impacts of Use and Abuse of Nature in Catalonia with Proposals for Sustainable Management
This paper provides an overview of the last 40 years of use, and in many cases abuse, of the natural resources in Catalonia, a country that is representative of European countries in general, and especially those in the ...
Three-Dimensional Magnetotelluric Characterization of the Travale Geothermal Field (Italy)
The geoelectrical features of the Travale geothermal field (Italy), one of the most productive geothermal fields in the world, have been investigated by means of three-dimensional (3D) magnetotelluric (MT) data inversion. ...
Revision of the Maastrichtian-Palaeocene charophyte biostratigraphy of the Fontllonga reference section (southern Pyrenees, Catalonia, Spain)
The Fontllonga section is one of the best-known stratigraphic sections wordwide for the study of charophyte biostratigraphy of the Maastrichtian and lower Palaeocene. An updated proposal for the charophyte biostratigraphy ...
Geoelectric dimensionality in complex geologic areas: Application to the Spanish Betic Chain
Rotational invariants of the magnetotelluric impedance tensor may be used to obtain information on the geometry of underlying geological structures. The set of invariants proposed by Weaver (2000) allows the determination ...
Las unidades litoestratigráficas del Eoceno pre-pirenaico del Ripollés oriental (prov. de Gerona y Barcelona)
En este trabajo se definen una serie de unidades litoestratigréficas para el Eoceno prepirenaico del Ripollés oriental (provincia de Gerona y Barcelona) y se da un corte general del mismo que pone de manifiesto los cambios ...
Terrestrial Isopods from Spanish Amber (Crustacea: Oniscidea): Insights into the Cretaceous Soil Biota.
Terrestrial isopods (Crustacea: Oniscidea) are a model group for studying the colonization of land. However, their fossil record is remarkably scarce and restricted to amber inclusions, and therefore amber deposits represent ...
Análisis morfométrico de bloques de tsunamis en la isla de Formentera, islas Baleares
Se caracterizan morfométricamente 86 bloques de grandes dimensiones ubicados sobre dos áreas de la isla de Formentera y los islotes de s'Espardell y s'Espalmador. Estos bloques se encuentran ubicados sobre acantilados ...
AMADEUS: advanced manipulation for deep underwater sampling
AMADEUS is a dexterous subsea robot hand incorporating force and slip contact sensing, using fluid filled tentacles for fingers. Hydraulic pressure variations in each of three flexible tubes (bellows) in each finger create ...
