The main issue of the Collaborative Research Centre 267 Deformation processes in the Andes since 1993 is the investigation of the interaction between tectonic and climatic processes controlling subduction orogeny. Along more than 7000 km with its large variability of boundary conditions the Andean active margin system offers an ideal natural laboratory.
The main area of investigation was concentrated in the Central Andes (Altiplano-Plateau between 19° und 24°S). Since 1999 we started in the Northern Patagonian Andes (36°-42°S). This comparative study of the central and southern areas of the Andes aims to identify the controlling parameters responsible for the extremely different evolution of the subduction orogen in terms of plateau formation or crustal thickening under very different climatic but identical plate boundary conditions. In the Southern Andes the geophysical surveying was accompanied by extensive geological studies in order to quantify the architecture and tectonic evolution of the continental margin. The results of this multidisciplinary approach are integrated into modelling studies of subduction orogeny.
