Sujoy Mukhopadhyay’s research group is focused on understanding the feedbacks and linkages between processes operating within the deep mantle and on Earth’s surface. The inert nature of the noble gases make them unique geochemical tracers for studying a variety of processes including the formation of terrestrial atmospheres, low temperature thermochronometry, exposure age dating, geochemical evolution of the Earth’s mantle, and magma degassing.

Congratulations Dr. Tucker!

Jonathan Tucker defended his Ph.D. on “A Portrait of Terrestrial Volatile Evolution from Mantle Noble Gases.” He will go to the Department of Terrestrial Magnetism on a Carnegie Postdoctoral Fellowship.

Earth remembers accretion

Our new paper is out today in Science: Preservation of Earth-forming events in the tungsten isotopic composition of modern flood basalts by Hanika Rizo et al. W anomalies in the mantle demonstrate that the Earth has not erased signatures from the main stage of planet formation. Also see the Perspective by Tais Dahl.
