Graduate student Kuan-Yu Lin set sail in April for the Atlantis Massif (~30N, 42W in the Atlantic Ocean) on the drill ship Joides Resolution. He is participating in Expedition 399 “Building Blocks of Life, Atlantis Massif” of the International Ocean Discovery Program. Follow the progress of the expedition here. Read more about Kuan-Yu’s research here.
The kindergarten class from the UD Lab School came to Penny Hall to learn about rocks on Tuesday afternoon. They were excited to hold pieces of magma, look at fossils, and see fluorescing minerals!
Congratulations to Melinda Bahruth on her successful thesis defense! Melinda presented her work on “Basaltic Breccia Constraints on the Shallow Rheology of the Gofar Transform Fault”. Despite the early hour on Friday, the Zoom audience was packed and overflow seating was needed for the in-person crowd in Penny Hall.
Our article about ship-based research into deformation and seismicity of the Gofar Transform Fault is published in Eos: Boettcher, M.S., E.C. Roland, J.M. Warren, R.L. Evans, and J.A. Collins, 2023. Observing a seismic cycle at sea, Eos, 104, https://doi.org/10.1029/2023EO230076.
Nadine Grambling has joined the Mantle Processes group as a postdoctoral scholar! She will be studying olivine fabric development by combining rock deformation experiments with analysis of samples from the Talkeetna Intraoceanic Arc in Alaska. Her work is supported by NSF project EAR-2113408 and is a collaboration with Ningli Zhao (Carnegie Institution) and Greg Hirth […]
Graduate student Abigail Nalesnik and UD affiliate professor Kendra J. Lynn are featured in this amazing interactive piece by Tracey Bryant and Dave Barczak for the UD Research magazine. The story describes their encounter with a volcanic eruption at Kīlauea’s Halema’uma’u crater in 2021.
Current lab members Kuan-Yu Lin and Abby Nalesnik, along with affiliated lab member Kendra J Lynn, will present their research at the 2022 Goldschmidt Conference in Honolulu, HI: Lin, K.-Y., Warren, J. M., & Davis, F. A. (2022). Evaluating the effects of spreading rate and melt addition on the closure temperatures recorded by peridotite thermometers. […]
After two years of virtual conferences, Mindy Bahruth and Kuan-Yu Lin where able to attend the 2021 AGU Fall Meeting in New Orleans!
An article on the role of seawater infiltration for oceanic transform fault seismicity has been published in the latest issue of Nature Geoscience. Oceanic transform faults are a major category of plate-bounding faults that cross-cut the mid-ocean ridge system. This study by Arjun Kohli, Monica Wolfson-Schwehr, Cecile Prigent, and Jessica Warren incorporates seawater hydration into […]
Former lab member Suzanne Birner has published an open access paper titled “Melt addition to mid-ocean ridge peridotites increases spinel Cr# with no significant effect on recorded oxygen fugacity“. In this paper, we report geochemical data, petrographic observations, and oxygen fugacity estimates for Southwest Indian Ridge peridotites. We show that low to moderate degrees of […]
