Washington, DC — Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than previously thought, according to new work from the Geophysical Laboratory's Yingwei Fei and Colin Jackson published in Nature.
The Geophysical Laboratory's weekly seminar series continues with GL's own Zhixue Du. He will present, "Origin of Earth’s ancient magnetic field: driven by MgO exsolution?"
Washington, DC— A team led by the Geophysical Laboratory's Yingwei Fei, a experimental petrologist, and Cheng Xu, a field geologist from Peking University, has discovered that a rare sample of the mineral majorite originated at least 235 miles below Earth’s surface.
The Geophysical Laboratory's weekly seminar series continues with Johnny Zhang of Scripps. He will present, "Experiments on Fe-Ni-S Liquid with Silicate Solids under Mantle Conditions: Implications for Deep Carbon, Primordial Components and LLSVPs”
The Geophysical Laboratory's weekly seminar series continues with June Wicks from Princeton University. She will present, "From Super-earth interiors to our own earth’s surface: using dynamic compression to study our universe."
The Geophysical Laboratory's weekly seminar series continues with Colin Jackson from the Geophysical Laboratory. He will present, "Discrete stages of core formation survive the moon forming impact."
Washington, DC— Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet’s outer core, a phenomenon called a “geodynamo,” generates the field.
