Transient storage and removal of sediments in intermontane basins: the interplay between climate, tectonics and surface processes (co-organized)
Convener: Paolo Ballato  | Co-Conveners: Daniel Garcia-Castellanos , Ghasem Heidarzadeh , Taylor Schildgen 

Intermontane basins are transient sediment traps located in diverse tectonic settings that can experience oscillatory episodes of basin filling and excavation. Basin-wide aggradation may be associated with increased sediment flux, reduced fluvial connectivity with the foreland, and/or internal drainage conditions, while basin incision and excavation may occur during enhanced fluvial discharge, headward erosion and knick-point migration, and basin overspilling. Furthermore, sediment storage and removal may have an impact on the shallow crustal stresses, and hence may control the locus of active deformation, with potential feedbacks on local climate and surface processes. Overall, this complex pattern of sedimentation, erosion and deformation highlights the rich interplay between tectonics, climate, and Earth-surface processes, in controlling the life span of intermontane basins.
Here we aim to explore the significance of intermontane basins as recorders of tectonics, climate and efficiency of surface processes with classical field, laboratory-based, numerical and physical modelling studies. Our goal is to stimulate new discussions and spark innovative visions among the community of scientists working on sedimentary, geomorphic, and deformation processes at different spatio-temporal scales.
