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
El volcanismo oligo-mioceno del Sulcis, SO de Cerdeña (Italia) presenta la particularidad de contener rocas peralcalinas y alcalinas de un ambiente geodinámico anorogénico posterior a la actividad orogénica relacionada con ...
Optimization of the use of diamond indicator minerals in diamond exploration in kimberlites
Ti-rich minerals occur in xenoliths of metasomatized mantle peridotites, MARID and PIC. Xenocrysts produced by disaggregation during the intrusion have equivalent compositions. Early crystallization in the first intrusive ...
Modelization of the vitrification of sewage sludge using a basaltic matrix
Sewage sludge is a high volume, potentially toxic waste generated during the decontamination process of wastewater. Improved solutions for waste disposal require its conversion into an end product or at least a raw material ...
Stable isotopes analysis to assess abiotic and biotic remediation of groundwater polluted by chlorinated methanes
Carbon tetrachloride (CT) and chloroform (CF) are chlorinated methanes (CMs) which have been released to the environment for decades owing to scarce waste management. Since they are dense non-aqueous phase liquids (DNAPLs), ...
Sequential fluid migration along a fold and thrust belt: SE Pyrenees from Late Cretaceous to Oligocene
The south eastern Pyrenees allowed us to study the relationships between fluid flow and deformation in a complete section of a well-preserved fold and thrust belt. Furthermore, this study enables us to decipher the main ...
Geochemistry of rare earth elements in acid mine drainage precipitates
Rare earth elements (REE) are known as the lanthanide series (La-Lu) plus yttrium (Y) and scandium (Sc). REE are essential materials for modern industries and especially for green technologies (wind turbines, batteries, ...
Evolución metalogenética de complejos carbonatíticos en contexto hipoabisal y plutónico: Bonga y Monte Verde (Angola)
En Angola afloran complejos carbonatíticos en todos los niveles de emplazamiento tanto plutónico, hipoabisal como volcánico. Recientemente, se han caracterizado en detalle algunos de estos complejos debido a las mineralizaciones ...
The Petrogenesis of the ophiolitic mélange of Central Cuba: origin and evolution of oceanic litosphere from abyssal to subduction and suprasubduction zone settings
This PhD is about the serpentinitic matrix, mafic crust and exotic ultramafic blocks of the Villa Clara serpentinitic mélange (VCSM) in central Cuba in an attempt to evaluate the evolution of oceanic lithosphere. Each of ...
Multidisciplinary characterization of diapiric basins integrating field examples, numerical and analogue modelling: Central High Atlas Basin (Morocco)
The complexity of the interplay between tectonics and sedimentation increases when salt tectonics is involved because of the ductility of salt and its ability to flow. Discrimination between extensional tectonics and ...
