Abby Nalesnik’s paper on olivine crystal chemistry from the Kulanaokuaiki eruption of Kīleau Volcano, Hawai’i, has been published in the journal Contributions to Mineralogy and Petrology. Nalesnik, A.R., K.J. Lynn, T. Rose, J.M. Warren, D.C.S. Ruth, K.-Y. Lin, and D.A. Swanson, 2026. Storage timescales and the crystal growth history recorded in the layered reservoir of […]
Congratulations to Torii Nienow and Oliver Solar on their graduations from the University of Delaware. Torii received her Master of Science degree and Oliver was awarded a Bachelor of Science, Cum Laude with Distinction. We will miss you!!
Exciting results from our 2019-2022 deployment of ocean bottom seismometers on Gofar transform fault in the equatorial Pacific have been published in Science. The paper, led by Jianhua Gong, assistant professor at Indiana University, includes results from the 2019 expedition led by Jessica Warren, who discusses how fast the fault moves in this UDaily article.
Congratulations to Oliver Solar on his senior thesis, “Geochemical investigation of melting processes in mantle peridotites from the Talkeetna Arc”. His project explores the composition and oxygen fugacity of the subarc mantle from the Talkeetna Arc in Alaska. Oliver’s research was supervised by Prof. Jessica Warren at the University of Delaware and Dr. Elizabeth Cottrell […]
Congratulations to Torii Nienow on successfully defending her Master’s thesis at the University of Delaware. Her thesis, “Microstructural Analysis of Mylonite Peridotites from the Garrett Transform Fault”, explores the interaction of melt and fluid during ductile deformation deep in a fault.
The Warren Lab was excited to see their 5 tons of seafloor samples during a trip to Woods Hole Oceanographic Institution. These samples were collected in Oct-Nov 2025 during R/V Revelle expedition RR2509 to Chain transform fault in the equatorial Atlantic. From November to February, the rocks were shipped from Cape Verde to the USA […]
Members of the Mantle Processes group are participating in an expedition to Chain transform fault in the Atlantic Ocean. Read more about the project here.
Congratulations to Prof. Suzanne Birner (Berea College) on receiving the F.W. Clarke Award from the Geochemical Society! A former student in the Mantle Processes Group, Prof. Birner is receiving the award for “her series of papers that decipher and document the processes occurring in the Earth’s mantle that have generated variations of several orders of […]
Congratulations to Dr. Abigail Nalesnik on a successful defense of her PhD, titled “A Geochemical and Physical Investigation of the Kulanaokuaiki Tephra of Kīlauea Volcano, Hawaii”. Abigail will be moving to Concord University for a postdoc with Prof. Stephen Kuehn as part of the NSF-funded FAIR Data Communities – Tephra Information Portal (TIP) project.
Postdoctoral scientist Christine Chesley’s controlled-source electronmagentic study of Gofar transform fault was published today in Science Advances. This paper presents exciting evidence for deep fluid flow and brine formation within an oceanic fault. Read more about it here. Chesley, C., R. Evans, J.M. Warren, et al., 2025. Evidence for crustal brines and deep fluid infiltration […]
