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 ...
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 ...
The shift from subduction-initiation to true subduction in intra-oceanic systems: tectonic, magmatic and metallogenic evolution of Early Cretaceous arc-related units of Central and Oriental cordilleras in the Dominican Republic
The Maimón and Los Ranchos formations in Central and Oriental Cordilleras, Dominican Republic, Hispaniola Island, are acknowledged to be representative of the most primitive tholeiitic magmatic series recorded in the Greater ...
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 ...
Uso de técnicas geofísicas en la planificación y gestión de recursos hídricos subterráneos. Aplicación en acuíferos mediterráneos = Using geophysical techniques in planning and management of groundwater resources. Application in Mediterranean aquifers
La presente tesis tiene como objetivos el desarrollo, aplicación, calibración y validación del uso de información geofísica para la gestión, la caracterización y el estudio de la vulnerabilidad a la contaminación de los ...
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 ...
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 ...
