Modeling and monitoring vertical motion processes from geodetic to geologic time scales
Convener: Yi-Wei ChenECSECS | Co-conveners: Roland Pail, Hans-Peter Bunge, Anke Friedrich, Michael Krautblatter
Vertical motions of the Earth’s lithosphere away from an isostatically compensated state provide a powerful lens into the dynamic behavior of the sublithospheric mantle. These motions can now be monitored geodetically at unprecedented precision. At the same time, geological records provide invaluable spatial-temporal information about the history of vertical lithosphere motion, for instance through provenance, stratigraphic and other proxies. Altogether, the combination of geodetic and geologic observations provide extraordinary opportunities to constrain deep earth processes in geodynamic forward and inverse models of past mantle convection. The challenges of using Earth's surface records to better understand deep Earth processes involve (1) signal separation from other uplift and subsidence mechanisms, such as isostasy and plate tectonics, and (2) different spatial resolutions and scales between models and observables. (3) The challenges of recognizing on what ( intercontinental) scales to compile geologic and stratigraphic data.

In this session, we aim to bring together researchers interested in the surface expression of deep Earth processes from geodetic to geological time scales using multi-disciplinary methods, including (but not limited to) geodetic, geophysical, geochemical, geomorphological, stratigraphic, and other observations, as well as numerical modeling. We welcome studies that tackle challenges and address questions surrounding mantle convection and its surface manifestation in the Mesozoic and Cenozoic times. Studies using a multidisciplinary approach are particularly encouraged.
