Constraining the Thermal Structure in the Upper Mantle with Interdisciplinary Perspectives and Multiple Datasets

Session ID#: 162176

Session Description:
The thermal evolution of the oceanic upper mantle has long been explored with seismic tomographic methods such as those that use surface wave phase velocities, surface wave shear velocities, and body wave travel times. Ambient seismic noise datasets have been proven to significantly improve the resolution of source-derived seismic images of oceanic lithosphere, allowing us to put important constraints on physical properties of the mantle. To complement information obtained from seismological methods, other methods such as petrology, geochemistry, and geophysical modeling must be considered. In this session, we invite contributions from geophysical methods, geodynamic modeling, geochemistry, and multidisciplinary approaches, to provide a comprehensive picture of processes in the upper mantle and advance our understanding of the evolution of oceanic upper mantle.
