An article by Megan D’Errico, Matt Coble, and Jessica Warren has been published in American Mineralogist as part of a special collection on Planetary Processes as Revealed by Sulfides and Chalcophile Elements. The article presents in situ trace element data for sulfides from abyssal peridotites and uses modeling of lead contents to show that sulfides […]
Jessica Warren, Kendra Lynn, and Sierra Patterson presented research at the 2018 AGU Fall Meeting in Washington DC.
The Mantle Processes Group presented an exhibit, “Ocean Rocks!” at UD Coast Day. This exhibit displayed samples collected from the seafloor and styrofoam objects shrunken by sending them down to the seafloor! The exhibit was adapted from an event held at the National Museum of Natural History in June. More information is in this UDaily […]
The Mantle Processes Group spent 10 days in southwest Oregon and northern California for fieldwork in the Josephine Peridotite and Trinity Ophiolite. Colleagues from Brown University, Lamont Doherty Earth Observatory, University of Auckland, and University of Oregon joined us for parts of the trip. It was good to be back in the mantle!
Katie Kumamoto has joined Lars Hansen’s group at Oxford University as an NSF Postdoctoral Fellow. She will be working on the contributions of composition and length-scale to the peak strength of the lithosphere.
Kuan-Yu Lin has joined the Mantle Processes Group! Kuan-Yu completed his B.S. at National Cheng Kung University with a double major in Earth Sciences and Chemistry. He then completed his M.S. in Geosciences at National Taiwan University, with a thesis on the geochemistry of peridotites from ophiolites in Turkey.
Suzanne Birner is now an assistant professor at Berea College, where she is establishing a Geology program, beginning with the development of a new minor.
Melinda Bahruth has joined the Mantle Processes Group to work on deformed rocks from oceanic transform faults. Mindy completed her B.S. in Geology at Wichita State University and has been awarded a Graduate Scholars Fellowship by the University of Delaware.
Suzanne Birner and Katie Kumamoto graduated this weekend!
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. […]
