In recent years, photogrammetric models have become a widely used tool in the field of geosciences thanks to their ability to reproduce natural surfaces. As an alternative to other systems such as LiDAR (Light Detection ...
The objective of this thesis is to study the first-order dynamics of subduction systems characterized by opposite dip polarity in adjacent plate segments. The absence of previous studies analyzing the geodynamic evolution ...
In this thesis I investigated the status of the Mediterranean Sea ecosystem and the sustainability of its marine resources using an interdisciplinary approach, which combined data integration and modelling approaches. ...
Ademas de identificar y describir las formas del relieve, la geomorfologia tambien intenta descifrar los procesos y mecanismos causantes. Esto, que es válido para la geomorfología en general, lo es también para la geomorfología ...
Els objectius d’aquesta tesi se centren en la caracterització taxonòmica, paleoecològica, paleobiogeogràfica i biostratigràfica dels caròfits de les fàcies fluvials del trànsit Cretaci–Paleogen (K/Pg) de les conques ...
This thesis uses a field-based approach complemented with geophysical and well data to investigate the controlling factors on the geometry and kinematics of salt walls developed above extensional faults whose movement ...
[cat] Les partícules que sedimenten en el medi marí tenen un paper clau en el cicle biogeoquímic d’un bon nombre d’elements i, per tant, són essencials per al funcionament de l’ecosistema. L’estudi dels fluxos de partícules ...
L’estudi de la concentració i la distribució de metalls i metal·loides en ambients costaners ha guanyat rellevància durant els darrers quaranta anys, principalment a conseqüència de la creixent preocupació per llurs ...
[spa] La Formación Caspe corresponde a las facies fluviales de los depósitos de un abanico fluvial de edad oligo-miocena, referido en la literatura como Sistema aluvial del Guadalope-Matarranya. Dicho sistema tuvo su área ...
The widespread extensional deformation that took place during Jurassic to Cretaceous times in Western Europe and the North Atlantic margin resulted in the formation of several rift systems. Some of the resulting basins ...
The Iberian Peninsula is considered as a “micro-continent”, located between the Eurasian and the African plates. Several ranges formed during the Alpine orogeny, in the borders of the plate or intraplate. As part of this ...
This thesis uses different variants of geomechanical modelling approaches to investigate stress, strain and geometry distribution and evolution through time of the Tarfaya salt basin, located on the West African coast. ...
[eng] Geothermal energy is a renewable source of energy that harnesses heat from the Earth's interior. Temperature increases with depth, defining the geothermal gradient, which can be variable depending on the geological ...
The purpose of this PhD thesis is to evaluate the volcanic risk associated with San Miguel Volcano, one of the most active volcanoes of El Salvador, through assessing volcanic hazard, that is, identify how a volcanic system ...
[eng] The Mediterranean region is very sensitive to modern climate variability. Located in a temperate subtropical climatic zone and surrounded almost entirely by large continental masses, the Mediterranean region climate ...
The main objectives of this PhD thesis are the identification of the snow avalanche release areas and the snow avalanche flow regime characterization with the use of seismic data. We aim to search for new methods for ...
La predicción de las avenidas torrenciales en zonas de montaña está limitada por la complejidad de las inestabilidades meteorológicas que las generan (tormentas convectivas con un fuerte efecto orográfico), la rápida ...
In this thesis, the 3D structure and kinematics of the locally and mildly inverted Lower Austria Mesozoic Basin beneath the Alpine-Carpathian fold-and-thrust belt is described. This study has been carried out by the ...
The Maestrat basin was one of the most subsident basins of the Iberian Rift System, which experienced two main rifting events: Late Permian-Late Triassic and Late Jurassic-Early Cretaceous. Its inversion during the Cenozoic ...
Aquesta tesi té com a objectiu modelitzar el paleoclima del trànsit Eocè−Oligocè de la Conca de l’Ebre i conèixer com aquest canvi afectà a la flora local. Aquesta caracterització paleoclimàtica s’ha obtingut a partir de ...
