Geomorphic and geologic observations at the Earth's surface reflect the combined effects of erosional, tectonic, and deep-seated processes. Such surface observations therefore provide important constraints on mantle convection patterns and subduction dynamics through space and time, which compliment both studies of geophysical data and numerical simulation. However, using Earth's surface records to constrain deep-seated processes is complicated by (1) our as yet incomplete understanding of how mantle convection or subduction processes are manifest as surface forms and patterns, and (2) the effects of tectonic processes, spatio-temporal variations in climate, glacial isostatic adjustment, lithology, biota, and human alteration of landscapes and surface geology. We invite contributions that tackle these challenges and work toward identifying the surface expression of deep-Earth processes such as mantle convection, in different tectonic settings. We welcome studies that develop and apply a variety of approaches across temporal and spatial scales, including (but not limited to) geomorphic analysis, geophysics, thermochronometry, isotope and cosmogenic nuclide measurements, and numerical and analogue modeling of both surface and deep-Earth dynamics. We hope that this session will provide opportunities for presenters from all backgrounds, demographics, and all stages of their scientific career to engage in this exciting and emerging geological problem via a multidisciplinary approach.

How to access GM9.14
Session GM9.14 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
