  • 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 […]

  • An article by Suzanne Birner, Jessica Warren, Liz Cottrell, and Fred Davis has been published in the July issue of the journal Geology. This article is available online via open access. In the Pacific Ocean, north of New Zealand, the collision of two tectonic plates has created the Tonga Trench, a massive gash in the sea floor, miles deep. […]

  • Mantle anisotropic viscosity results from the crystallographic alignment of olivine and influences a variety of large-scale geodynamic processes. This study, lead by Lars Hansen, presents torsion and extension experiments on pre-textured olivine aggregates to provide constraints on olivine viscous anisotropy. We found that the magnitude of anisotropy is similar among the different deformation geometries tested. These results form […]

    Invited review article on global abyssal peridotites

    This review article presents a global compilation of abyssal peridotite compositions, demonstrating that their compositions reflect a combination of melting, melt–rock interaction and source heterogeneity. This article is open access. Warren, J.M., 2016. Global variations in abyssal peridotite compositions, Lithos, 248-251, 193-219, doi:10.1016/j.lithos.2015.12.023.

  • Megan D’Errico’s paper on the geochemistry of peridotites from the Arctic Ocean has been published in Geochimica et Cosmochimica Acta. Based on modeling of peridotite compositions, we show that the presence of refractory harzburgites and thin overlying oceanic crust are best explained by low degrees of melting of a previously melted, heterogeneous mantle. D’Errico, M.E., J.M. Warren and M. […]
