Tectonics, Volcanology, and Petrology

Understanding tectonic and volcanic processes and their high-temperature rock record.

We use geophysical and geochemical methods to investigate a wide variety of geological problems that shape Earth’s interior and surface through volcanism and tectonism. We employ observational, experimental, theoretical, and computational approaches. Active research areas include: microstructural analysis of deformed rocks and xenoliths to investigate deformation mechanisms and the rheology of the crust and mantle; the chemical and physical processes associated with magma formation, migration, and eruption; geodynamics of ice sheets and mantle rebound; the seismic structure of the lithosphere and mantle; mechanics of faulting and earthquakes.

New research offer clues to Mars’s history, including what violent collisions it experienced in the past and how it lost its magnetic field. Professor Ingrid Daubar, former member of the InSight science team, commented on these recent studies, saying, “There are connections to our own planet, to how planets form in general and to how we understand different planets outside our solar system.”

A new publication in G3 led by Assistant Professor Emily H. G. Cooperdock untangles the systematics of uranium enrichment for serpentinites from different tectonic settings and explores potential mineral hosts. The researchers found that "uranium enrichment is most common in the upper 100m of the seafloor and is not correlated with degree of serpentinization. We also find a correlation between U concentration and iron-oxidation, which we use to suggest that U is hosted in ferric iron minerals, possibly iron-oxides." The paper also provides insights on using uranium as a tracer for tectonic setting, fluid rock interactions, and redox records in the solid Earth system.
