GM9.1

The coupling between tectonics, climate and surface processes governs the dynamics of mountain belts and basins. First order constraints on this coupling are provided by geomorphic and sedimentary records, including longitudinal river profiles, fluvial terraces, downstream fining trends, growth strata, sediment provenance, sequence stratigraphy, and changing depositional environments. Moreover, the increasing integration of geochronological methods for quantifying erosion rates and source-to-sink sediment transfer with landscape evolution, stratigraphic, climatic, and tectonic models allows to advance our understanding of the interactions between surface processes, climate and tectonic deformation.

We invite contributions that use geomorphic and/or sedimentary records to understand tectonic deformation, climate histories, and surface processes, and welcome studies that address their interactions and couplings at a range of spatial and temporal scales. In particular, we encourage coupled catchment-basin studies that take advantage of numerical/physical modelling, geochemical tools for quantifying rates of surface processes (cosmogenic nuclides, low-temperature thermochronology, luminescence dating) and high resolution digital topographic and subsurface data. We also encourage field or subsurface structural and geomorphic studies of landscape evolution, sedimentary patterns and provenance in deformed settings, and invite contributions that address the role of surface processes in modulating rates of deformation and tectonic style, or of tectonics modulating the response of landscapes to climate change.
