  • Suzanne Birner’s article on mantle oxygen fugacity is now published in Earth and Planetary Science Letters. In this contribution, we show a broad congruence in the oxygen fugacity recorded in basalts and in peridotites from the Southwest Indian Ridge. While the two proxies for fugacity are in overall agreement, peridotites also indicate local redox heterogeneity. […]

    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 […]

    Cecile Prigent joins the Mantle Processes Group

    Cecile Prigent has joined the Mantle Processes Group as a postdoctoral scientist. Cecile received her PhD from the Universite Grenoble-Alpes, France, working with Stephane 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.
