TRB Andes workshop 2022

The South American Andes have for many years been one of the main study areas of researchers at ISTerre, and some people may ask what is left worth studying in the Andes today. For providing a clear answer to this question and to discuss current and future research efforts in and around the Andes, ranging from geodynamic question related to subduction style, the occurrence of serpentinites, mountain building, metamorphic events, foreland or forearc basin evolution, over resources, weathering, environmental geochemistry to natural hazards, surface processes, paleoclimate and biodiversity evolution, the TRB team of ISTerre is organizing a 1-day workshop May 18th 2022 with contributions from students and researchers at ISTerre.

Workshop organization
The objective is to provide an overview on our research activities in and around the Andes via 15-minute presentations followed by 5 minutes for immediate discussions. At the end 30 minutes will be for further round table discussions.
