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

我们建议德国/阿根廷IRTG对阿根廷安第斯山脉和邻近前陆盆地的源-链系统进行跨学科研究。我们的研究解决了构造、气候、侵蚀、沉积物沉积之间的复杂关系，以及容易产生、运移和聚集油气资源和成矿的环境条件。前陆和向安第斯造山带内部的过渡以持续的、但高度历时的、空间上不同的构造作用为特征，此外，在地貌、降雨和侵蚀方面存在明显的对比。总而言之，这些特征使该地区成为在多个时空尺度上研究地表过程及其影响泥沙产生和质量转移的构造和气候强迫因素的杰出自然实验室。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今后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、沉积物输送系统的变化和寻求经济资源的综合影响方面。这些活动的基础包括一系列具有挑战性的研究项目、跨学科培训、在阿根廷的长期访问、相互承认的学位观点以及联合顾问。

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.
