The graduate school GeoFluxes explores the role of fluid exchange in Earth and Environmental Systems, with particular attention to Georesources and is devoted to promote the research of NTH in the field of Geosciences. The graduate school benefits from the expertise at NTH and at the Geozentrum Hannover. The research and the teaching will focus on the formation and evolution of Georesources and is best suited to complement the well-established applied research field in Geosciences and to develop a transformative research direction, from fundamental to applied Geosciences. GeoFluxes will focus on the formation and evolution of the major Georesources Soils and Metals and has the potential to integrate scientific excellence across traditional disciplines within the Earth Sciences. GeoFluxes associates abiotic processes occurring at depth (metal deposits, active faults) with biogeochemical and physical processes occurring at the critical zones of the Earth (e.g., organic material and metal transfer in soils, landscape evolution). GeoFluxes covers the most challenging and emerging fields of research worldwide: it focuses on the critical zones located close to the Earth surface where anthropogenic and global changes will have particular socio-economic consequences in the future.
