Our latest paper entitled „Slab Stagnation in Earth’s Shallow Lower Mantle linked to an Increase in Mantle Viscosity“ is published in today’s on-line version of “Nature Geoscience”. The paper discusses our recent experimental findings about the deformation behavior of (Mg,Fe)O ferropericlase in the lower mantle and can be found here. Also, have a look at the associated “News and Views” article (here) by Patrick Cordier. If you want to read even more, press releases can be found here (University of Bayreuth) and here (University of Utah).
