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 ...
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. ...
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 ...
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 ...
El metamorfismo hercínico de grado muy bajo del Priorat Central
Las rocas del Paleozoico del Priorat Central (Cadena Costera Catalana, NE de la Península Ibérica) han sido sometidas a un metamorfismo regional hercínico de grado muy bajo que alcanzó el límite entre la zona diagenética ...
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 ...
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 ...
Estudio Geológico y Metalogenético del Basamento Precámbrico del Sahara Occidental
En el Sáhara Occidental hay dos unidades principales: la cobertera sedimentaria del Fanerozoico y un basamento cristalino que forma parte del cratón del África Occidental, constituido desde el Paleoarcaico al Paleoproterozoico. A ...
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 ...
Evolution of the lithospheric mantle in NE Angola: implications for diamond exploration
Angola is currently the 8th largest diamond producer in the world, but for historical reasons the subcontinental lithospheric mantle (SCLM) in the Congo-Kasai craton is still poorly studied. However, an understanding of ...
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 ...
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 ...
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 ...
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, ...
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 ...
Los minerales pesados del Mioceno de la fosa neógena del Vallès-Penedès. Caracterización, evaluación e hipótesis de procedencia
1. Se ha realizado el estudio de los minerales pesados de los materiales detríticos del Mioceno de la fosa neógena del Vallès-Penedès, así como, y con carácter comparativo, los del Holoceno más reciente que aportan los ...
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 ...
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 ...
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 ...
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 ...
