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.
Gigantic masses in the Earth’s mantle have existed for more than 4 billion years.
Research about the antiquity of the continental sized large low shear wave velocity provinces at the core-mantle boundary was published in Geochemistry, Geophysics, Geosystems: Primitive helium is sourced from seismically slow regions in the lowermost mantle by Curtis Williams, Sujoy Mukhopadhyay, Maxwell Rudolph and Barbara Romanowicz, and was featured in GeoSpace.
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.
