    Smaller is stronger for olivine

    Research by Katie Kumamoto, Jessica Warren, and colleagues on the strength of olivine has been published in Science Advances. Our research suggests that tectonic plates are weaker than previously thought due to a size effect in olivine, the most abundant mineral in the Earth’s mantle. The article is summarized by Karen Roberts in this UDaily […]

    Kendra J. Lynn joins the Mantle Processes Group

    Kendra Lynn has joined the Mantle Processes Group as a postdoctoral scientist. Kendra received her PhD in Geology and Geophysics from the University of Hawai‘i. She worked with Mike Garcia on compositional zoning in olivine from Kīlauea tephras, focusing on diffusion chronometry as a tool for investigating magmatic processes. At the University of Delaware, Kendra will […]

    Cécile Prigent joins the Mantle Processes Group

    Cécile Prigent has joined the Mantle Processes Group as a postdoctoral scientist. Cécile received her PhD from the Université Grenoble-Alpes, France, working with Stéphane Guillot and Philippe Agard on the interaction of subduction fluids with peridotites in the Oman Ophiolite. Her research focus is on the feedbacks between ductile deformation and fluid circulation.

  • In an open access article published in the Proceedings of the National Academy of Sciences, Lars Hansen, Jessica Warren, and Chao Qi use experiments on olivine aggregates to show that the base of the lithosphere is best represented by thermal models that predict a gradational boundary. The deformation experiments indicate that changes in seismic anisotropy can be matched by […]
