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.

我们提出了一个德国/阿根廷IRTG进行跨学科研究的源-汇系统的阿根廷安第斯山脉和邻近的前陆盆地。我们的研究探讨了构造、气候、侵蚀、沉积物沉积以及容易产生、迁移和聚集碳氢化合物资源和成矿作用的环境条件之间的复杂关系。前陆和过渡到安第斯造山带内部的特点是持续的，但高度历时性和空间上不同的构造作用，除了在救济，降雨和侵蚀明显的对比。总之，这些特点使该地区成为一个杰出的自然实验室，研究表面过程及其构造和气候强迫因素，影响沉积物的生产和质量转移的多个时空尺度。鉴于全球变化对降雨模式和强度的未来预测影响，造山带-前陆耦合系统构成了未来几十年面临重大社会挑战的地区，特别是在地震活动、日益常见的水文气象极端事件、沉积物输运系统变化和寻求经济资源的综合影响方面。这些活动的基础是选择具有挑战性的研究项目，跨学科培训，在阿根廷的长期访问，相互承认的学位的角度，以及联合招生。
