TRB Alps online Workshop

ONLINE WORKSHOP

Is there anything left worth studying in the Alps? This is the question that some people may ask given the long history of geoscience research in the European Alps over the past 150 years. For providing a clear answer to this question and to discuss current and future research efforts in and around the Alps, ranging from the rift-inherited heterogeneities and their impact on Alpine collision, over the alpine metamorphic, structural deformation and exhumation histories, to passive margin and foreland basin evolution, and late Neogene – Quaternary paleoclimate and biodiversity evolution, the TRB team of ISTerre holds a 1-day online workshop with contributions from students and researchers at ISTerre and other laboratories and institutions.

Workshop organization
The objective is to provide an overview on our research activities in anad around the Alps via 15-minute presentations followed by 5 minutes for immediate discussions. At the end of each subject session an additional 40 minutes will be for further round table discussions.
