In order to understand the current state of the natural rocky environment and its heterogeneity, we require to study the interaction and time evolution of the numerous geological processes that have contributed to the ...
Pedrosa Pàmies, Rut (Data de defensa: 2016-09-09)
One of the grand challenges in marine biogeochemistry is to improve our understanding on the temporal (seasonal and multi-annual) and spatial (regional and global) variability of ocean uptake of CO2, and the physical and ...
Blanch Gorriz, Xabier (Data de defensa: 2022-03-17)
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 ...
Peral, Mireia, 1979- (Data de defensa: 2020-03-20)
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 ...
Piroddi, Chiara (Data de defensa: 2016-11-21)
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. ...
Rivera Martínez, Jesús (Data de defensa: 2017-07-18)
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 ...
Vicente Rodríguez, Alba (Data de defensa: 2017-06-28)
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 ...

[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 ...
Roma Nuñez, Maria (Data de defensa: 2020-02-27)
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 ...
Seillé, Hoël (Data de defensa: 2016-07-26)
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 ...
Linden d’Hooghvorst Rodríguez, Jean Joseph van der (Data de defensa: 2021-04-20)
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. ...
Mitjanas Colls, Gemma (Data de defensa: 2023-01-20)
[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 ...
