Continents of the underworld come into focus
Research by our group about the nature of the deep Earth, led by Dr. Curtis Williams, was recently featured in the Atlantic Magazine.
Isotope Geochemists Glimpse Earth’s Impenetrable Interior.
Research from our group was highlighted in AGU's EOS Centennial Collections.
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
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 [...]
