There and Back Again: Mantle xenon isotopes have a tale to tell

By parai on August 8, 2018 in news

NEW August 8, 2018 Our new paper published in Nature presents a model of xenon (Xe) cycling between the deep Earth and surface reservoirs. Volatiles (such as water, carbon dioxide, nitrogen and the noble gases) are outgassed from the Earth’s mantle due to volcanic activity. Surface volatiles are also injected into the mantle at subduction […]

Bio

I am a high-temperature isotope geochemist who primarily uses noble gases to address questions about how planetary bodies form and evolve over time. Explore these pages to learn more about my research group, our laboratory facilities and the research we pursue.

Research

We pursue topics related to the early Earth, lunar formation, the origin and evolution of Earth’s volatile budgets, chemical cycling between deep Earth and surface reservoirs, the nature of mantle heterogeneities and chemical constraints on geodynamics.
