Dynamic behaviour of salt rocks: exploring the interplay between deformation and recrystallization with full-field numerical simulations
[eng] Rock salt, primarily composed of halite, flows in a viscous manner in the solid state under a wide range of geological conditions, strongly affecting the dynamic evolution of sedimentary basins and orogens. The ...
Fluid migration, rock deformation, and mineral alteration in the Earth's crust. Insights from giant quartz veins and their host rocks in the Pyrenees
[eng] The interplay between fluid migration, rock deformation, and mineral alteration processes is key to determining dynamic variations in the Earth’s crust strength, understanding changes in the physicochemical properties ...
Mineral system in the mantle section of forearc ophiolites = Sistemes minerals a la secció mantèl·lica d'ofiolites d'avantarc
[eng] Ophiolitic sequences are the remnants of past oceanic lithosphere, including upper mantle and oceanic crust, that have been tectonically emplaced onto continental margins or volcanic arcs. Subduction-related ophiolites ...
Multi-isotopic tools for monitoring innovative remediation strategies in sites contaminated with halogenated organic compounds
[eng] Remediation strategies for groundwater contaminated with chlorinated solvents have advanced significantly in recent decades. However, understanding the complexity of factors influencing contaminant degradation and ...
Modelling the eruptive and pre-eruptive dynamics on Teide-Pico Viejo complex
[eng] The volcanic island of Tenerife (Canary Islands, Spain), the largest and most populated island of the Canarian archipelago, hosts the active Teide-Pico Viejo (T-PV) volcanic complex in its central region, known for ...
Rare earth elements, Yttrium and scandium retention in Fe- and Al-hydroxysulfates (basaluminite and schwertmannite) under the hydrogeochemical conditions of the Tinto River estuary (SW Spain)
[eng] Rare-earth elements (REEs: lanthanides, yttrium and scandium) are scarce in mining concentrations in the Earth’s crust, freshwater and seawater. In recent decades, REEs have become crucial to new technologies for ...
Salt sheet emplacement in fold-and-thrust belts: contributions from the Les Avellanes Diapir (South-Central Pyrenees)
[eng] This PhD Thesis presents the Les Avellanes Diapir (Serres Marginals, South-Central Pyrenees) as a field analogue of subaerial (extrusive) salt sheets in orogenic settings by understanding the emplacement mechanism, ...
Mecanismos de concentración de elementos críticos en la Carbonatita de Bailundo (Angola)
[spa] La reciente demanda e interés por los elementos críticos y en especial, por las REE’s ha impulsado en la última década diferentes trabajos relacionados con las carbonatitas. En muchos de ellos se demuestra la importancia ...
Optimization of induced denitrification strategies in water resources contaminated by agricultural and urban sources
[eng] Groundwater pollution poses a significant global environmental threat, mainly attributed to the oxidation of excess nitrogen during fertilization in aerobic conditions. The widespread occurrence of elevated nitrate ...
Post-caldera volcanism of Deception Island (Antarctica): new insights from Tephra studies and Port Foster Bay volcanic deposits
[eng] Deception Island (South Shetland Islands) is one of the most active volcanoes in Antarctica and has experienced over 20 explosive eruptive events in recent centuries. Recent eruptions in 1967, 1969, and 1970, as well ...
Caracterización de las mineralizaciones de Gavà: implicaciones geoarqueológicas
[spa] El municipio de Gavà (Cataluña) ha sido históricamente rico en recursos minerales, los cuales se han explotado desde hace más de 6.000 años. En este sentido, son especialmente destacables el caso de los minerales de ...
Isotopic characterization of precipitation and its relationship with groundwater in the Central Andes
The availability of water resources is increasingly limited worldwide. Therefore, optimal and sustainable management is necessary to ensure a balance between ecosystems and human rights and activities. In the arid Central ...
Polymorphism and crystallization behaviour of triacylglycerols. From pure components to mixtures rich in oleic acid
Quality attributes of food products such as visual appearance, melting behavior, or shelf-life are strongly determined by the crystallization behavior of natural fats and oils within. In turn, this behavior depends on the ...
Genesis and evolution of chromitites in ophiolite complexes from a mineralogical perspective
The finding of a suite of unusual minerals associated to ophiolitic chromitites questions traditional model for the formation of these rocks. These findings include minerals typically considered indicators of ultra-high ...
Carbon capture and storage in compressional basins: global to reservoir-scale assessments and integrated case study of the Puig-reig anticline (SE Pyrenees)
Carbon capture and storage (CCS) has been proposed as a potential technology to mitigate climate change. However, there is currently a huge gap between the global CCS deployment and that which will be ultimately required. ...
Fluid flow evolution in the Alpine-related basement and sedimentary cover structures in the Southern Pyrenees: an integrated structural, petrographic and geochemical approach
This PhD thesis examines the fracture-fluid interactions across different compressional structures affecting both Paleozoic basement and Mesozoic-Cenozoic cover lithologies in the Southern Pyrenees in order to investigate ...
Diverse origin and processes in the formation of diamond and other exotic minerals in ophiolitic chromitites
The discovery of ultra-high pressure (UHP), super-reduced (SuR), and continental crust-derived minerals in ophiolitic chromitites worldwide challenged the previous hypotheses for chromitite formation and motivated the ...
Optimization of induced denitrification strategies in polluted water bodies from agricultural sources
The worldwide persistence of nitrate (NO -) in groundwater is worrying since this compound has been related to human illnesses and to eutrophication of aquatic ecosystems. The main sources of pollution are linked to intensive ...
Estudi petrogenètic del complex intermedi-màfic-ultramàfic de Susqueda (Serralada Prelitoral Catalana). Implicacions en la gènesi i evolució del plutonisme hercinià del NE de la Península Ibèrica.
El Complex de Susqueda constitueix el major aflorament de roques màfiques i ultramàfiques associades a granitoides hercinians de la Serralada Costanera Catalana. Des dels inicis del segle passat, les roques màfiques de ...
El volcanismo calcoalcalino y peralcalino del suroeste de Cerdeña (Italia) y mineralizaciones asociadas
