Saharan dust inputs affect present day ecosystems and biogeochemical cycles at a global scale. Previous Saharan dust input reconstructions have been mainly based on marine records from the African margin, nevertheless dust reaching western-central Europe is mainly transported by high-altitude atmospheric currents and requires high altitude records for its reconstruction. The organic and inorganic...
The El Berrocal granite/U-bearing quartz vein (UQV) system has been studied as a natural analogue of a high-level radioactive waste repository. The main objective was to understand the geochemical behaviour of natural nuclides under different physicochemical conditions. Within this framework, the argillization processes related to fracturing and formation of the uranium-quartz vein were studied from...
