Dear Colleagues,
As the EGU abstract deadline is approaching (Jan. 9), we would like to draw your attention once more to the following session:
TS4.2/GM3.4/SSP2.3
Orogen-scale coupling between tectonics, erosion and climate
Convener: Frédéric Mouthereau
Co-Conveners: Peter van der Beek , Carole Petit
Confirmed invited speakers: Todd Ehlers, Andreas Mulch
The topographic evolution of collisional orogens results from interactions between crustal deformation, mantle-scale processes, and base-level and climate changes affecting erosional processes. To what extent the topography and relief of collisional orogens inherited from subduction and pre-convergence extensional stages is not yet clear. Basin-scale depositional system changes can modify exhumation patterns in mountain ranges but mechanisms driving these retroactions are still not well understood. The response of long-lived collisional orogens to late/post-orogenic climate changes has been addressed from a geodynamic modeling point of view but is still poorly defined from observations in natural systems. Among others, these questions outline the need to gain higher resolution data on erosional/depositional histories, paleoaltitudes and paleoclimates. In this session we welcome multidisciplinary contributions that integrate field-based studies, low-temperature thermochronology, geochronology, geochemistry, numerical geodynamic modeling and physical modelling of erosion as well as innovative approaches.
