Hydrothermal processes on Earth and Mars
Oceanic and continental hydrothermal systems have profoundly impacted the chemical composition and oxidation state of Earth’s lithosphere-hydrosphere-atmosphere system and shaped biological evolution throughout its history. Furthermore, they provide key societal benefits by producing deposits of critical materials and concentrating geothermal energy. We have been working to parameterize the feedbacks between hydrothermal processes, seawater chemistry, and the (bio)geochemical evolution of Earth and Mars using a combination of numerical models, laboratory experiments, and novel sample characterization. Serhat Sevgen is currently the primary group member working on this project.
