Mantle neon illuminates Earth’s formation
Our new paper is out today in Nature: Capture of nebular gases during Earth's accretion is preserved in deep-mantle neon by Curtis Williams and Sujoy Mukhopadhyay. To read some examples of press reports check out the UC Davis press release, Cosmos Magazine or the Daily Mail.
Mantle Xenon has a story to tell about the history of volatile cycling
A new paper detailing how xenon isotopes remember the history of volatile recycling is out today in Nature: Xenon isotopic constraints on the history of volatile recycling into the mantle by Rita Parai and Sujoy Mukhopadhyay. See some perspectives of the paper in the UC Davis press release and Physics Today
Congratulations Dr. Middleton!
Jennifer Middleton defended her PhD on Elemental fluxes to the seafloor: Pleistocene climate and submarine hydrothermal activity. She will go to Lamont Doherty on the prestigious Lamont prize postdoctoral fellowship.
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 prize DCO 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.
Multiple magma ocean and atmospheric loss episodes recorded in Earth’s volatile signature
Check out our paper in EPSL on Evidence for multiple magma ocean outgassing and atmospheric loss episodes from mantle noble gases by Jonathan Tucker and Sujoy Mukhopadhyay. A perspective on the article is in the LA Times.
Challenging ideas of deep Earth’s behavior and formation
Check out our paper in Nature on Early differentiation and volatile accretion recorded in deep-mantle neon and xenon. The paper presents evidence that the plume and MORB sources had differentiated within the first 100 million years and has not been homogenized since. This results provides new insights into the Earth's early history, volatile accretion, mantle [...]
