Abstract: Magma, molten rock in the Earth's interior,
surfaces at many sites of geologic interest. Perhaps its most vivid
manifestation is the volcanic eruption. Magmatism is also essential to mantle
convection and plate tectonics; it is universally present at plate boundaries,
including mid-ocean ridges and subduction zones. However, the coupling
between mantle convection, plate motions, and partial melts is not well
understood, spurring us to develop better models. In this talk, I shall
discuss recent progress on self-consistent multiscale models of partially
molten rock, computational challenges in closing these systems, and ongoing
work to couple such models to other geodynamical processes.
