Exploring multi-scale mantle dynamics with computational methods

Session ID#: 161471

Session Description:
The dynamics and evolution of Earth's mantle are governed by structures and processes interacting on a wide range of scales: long- wavelength mantle convection and large thermochemical structures are intimately linked with small-scale processes in the boundary layers, and understanding the effective properties of mantle rocks require insights on the mineral scale. These processes are not only multi-scale spatially but also act over strongly different timescales. Understanding the Earth's mantle across these scales is a problem typically outside the range of analytical solutions. The application of numerical methods to capture vastly different scales and the development of clever parameterisations to tackle this multi-scale problem are necessary.
This session will explore the link between Earth's mantle processes operating on different spatial and/or temporal scales. We invite contributions from various disciplines including geodynamics, seismology, mineral physics, and that highlight computational advances in tackling dynamical problems that span scales in time and space.
