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.
Suzanne’s presentation at the 2016 AGU Fall Meeting has been awarded the GeoPRISMS Prize for Outstanding Student Oral Presentation: Birner, Cottrell, Warren, Kelley, and Davis, 2016. Records of upper mantle oxygen fugacity gleaned from high-density sampling of basalts and peridotites at ultraslow ridges, AGU Fall Meeting, T32A-05. Congratulations Suzanne!!
Fred Davis’s paper in American Mineralogist is now published and open access: Davis, F.A., E. Cottrell, S.K. Birner, J.M. Warren, and O.G. Lopez, 2017. Revisiting the electron microprobe method of spinel-olivine-orthopyroxene oxybarometry applied to spinel peridotites, American Mineralogist, 102, 421-435, doi:10.2138/am-2017-5823.
Katie’s presentation at the 2016 AGU Fall Meeting has been awarded an AGU Outstanding Student Paper Award: Kumamoto, Wallis, Hansen, Armstrong, Wilkinson, and Warren, 2016. Olivine Strength in the Low-Temperature Plasticity Regime Measured Via Spherical Nanoindentation, AGU Fall Meeting, MR32A-05. Congratulations Katie!!
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 […]
Following the successful completion of her PhD at Stanford University, Megan D’Errico is moving to San Diego State University for a postdoctoral position in science education. Good luck Megan!
Suzanne Birner and Katie Kumamoto have been named the 2016 Harriet Benson Fellows. This award honors exceptional scholarship and research accomplishments by graduate students in the Department of Geological Sciences at Stanford University. The award was established by a gift from Dr. Harriet Benson to help further the careers of talented young female scientists. Congratulations […]
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 […]
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. […]
Megan D’Errico successfully defended her PhD thesis at Stanford University. Megan’s thesis is titled:Â Heterogeneity and Depletion of the Mantle Assessed from Abyssal Peridotite Geochemistry. Congratulations Megan!
