GRK 2018: SuRfAce processes, TEctonics and Georesources: The Andean foreland basin of Argentina (StRaTEGy)

We propose a German/Argentine IRTG to conduct an interdisciplinary study of the source-tosink system of the Argentine Andes and adjacent foreland basins. Our study addresses the complex relationships between tectonics, climate, erosion, sediment deposition, and the environmental conditions prone to the generation, migration, and accumulation of hydrocarbon resources and metallogenesis. The foreland and the transition to the Andean orogen interior is characterized by ongoing, yet highly diachronous and spatially disparate tectonism, in addition to pronounced contrasts in relief, rainfall, and erosion. Taken together, these characteristics make this region an outstanding natural laboratory to study surface processes and their tectonic and climatic forcing factors that impact sediment production and mass-transfer on multiple spatiotemporal scales. In light of future predicted impacts of Global Change on patterns and intensity of rainfall, coupled orogen-foreland systems constitute areas with important societal challenges over the next several decades, particularly with respect to the combined effects of seismicity, increasingly common hydro-meteorological extreme events, changes in sediment transport systems and the quest for economic resources. The basis for these activities constitutes a selection of challenging research projects, interdisciplinary training, long-term visits in Argentina, the perspective of mutually recognized degrees, and joint advisorship.
