  Information - GM15 Deep Alpine Valleys: recording the topographic, climatic and tectonic evolution of mountain belts (co-listed in CL)

Event Information
The temporal evolution and the formation of mountain range topography in response to tectonics and changing climate during the youngest geological history are one of the current challenges of Alpine geology. Processes governing the Quaternary evolution of Alpine-type landscapes include active deformation leading to faulting, surface uplift and/or local subsidence, fluvial/glacial erosion, and the response of erosion/sedimentation to vertical motions and changing glacial/interglacial conditions. The rationale of the session is to use Quaternary sedimentary archives of “deep” Alpine valleys from the inside of mountain ranges, which record both climatic changes and young deformation in order to assess these processes and their mutual dependencies. Suitable archives are conserved in valleys resulting from glacial overdeepening, in valleys following active faults, or in valleys resulting from combinations of these. Examples from the Alps include up to 800 m thick Quaternary sections, which promise unique data on terrestrial climate evolution and Alpine Quaternary tectonics. Reading such archives requires both, a multidisciplinary scientific approach, and major exploration efforts including geophysics and drilling. The session should reflect such scientific complementary expertise. It also intends to seed a group of scientists, who are willing to cooperate in thematically related projects.
