The evolution of orogenic systems is governed by processes operating across a wide range of spatial and temporal scales, extending from the asthenosphere through the lithosphere and the Earth’s surface, and acting from seconds to millions of years. Understanding the links between deep-seated, lithospheric and surface processes and their role in orogenic evolution is an increasingly prominent research topic that requires multidisciplinary approaches to gain robust spatio-temporal constraints. This involves the integration of data generated from a variety of techniques such as low- and high-temperature thermochronology, geophysics, tectonics, petrology, geochemistry, sedimentology, structural analysis, geomorphology, and modeling.
Such a strategy enables the reconstruction of the timing, rates, and magnitude of processes driving orogenic evolution, as well as their relationships with mantle, crustal, and surface dynamics.
This session focuses on the intrinsic links between surface and deep-Earth processes in shaping orogenic systems and controlling their spatial and temporal evolution. Topics include the exhumation and surface uplift history of mountain ranges and orogenic plateaus, evolution of foreland and intermountain sedimentary basins, methodological developments on the integration of diverse dataset, landscape evolution, and tectonic plate reconstructions. Research focused on both collisional and subduction-related orogens affected by hinterland extension is welcome.
