Snow avalanches are extended moving sources of infrasonic and seismic energy. The acoustic and seismic wave fields generated by an avalanche is a complex natural phenomenon produced by the interaction of the flow with its ...
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 ...
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 ...
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 ...
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. ...
Els sediments marins profunds són claus per a la comprensió de la variabilitat del clima al llarg de la història de la Terra. Aquests sediments contenen una gran varietat d’indicadors per reconstruir canvis tan de l’oceà ...
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 ...
Hom considera que els oceans són sistemes altament complexos, la dinàmica dels quals depèn de la interrelació de processos físics, químics i biològics. En aquests context, l’estudi dels intercanvis verticals de matèria ...
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 ...
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 addresses the tectonic and paleogeographic evolution of the SW Iberia Margin from the Mesozoic rifting stage to the post-rifting collision of Late Cretaceous through Miocene times and transpressive stages of ...
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 ...
El objetivo principal de la Tesis realizada ha consistido en el conocimiento de la fauna de organismos edáficos y acuáticos preservados como bioinclusiones en ámbar español de los yacimientos albienses de Peñacerrada I y ...
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 ...
The thesis presented here spins off from the 2-year oil-industry project entitled “Salt Tectonics Modelling at Kuqa Foreland Fold and Thrust Belt, Tarim Oilfield” that was a collaboration between the American-based company ...
Monitoring the elastic properties of the subsurface is of a special interest to mitigate the associated risk with natural and artificial hazards. In the last decade, coda-wave interferometry has become an excellent tool ...
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 ...
Studies of mountain belts worldwide show that along-strike changes are common in their foreland fold-and-thrust belts. These are typically caused by processes related to fault reactivation and/or fault focusing along changes ...
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 ...
Donada l’alta sensibilitat de la regió central de la Mediterrània occidental a la variabilitat climàtica, s’han reconstruït les condicions de la mar superficials i profundes així com de les atmosfèriques pels darrers 2.700 ...
