معرفی
James Day is a Professor in the Geosciences Research Division at the Scripps Institution of Oceanography, UC San Diego. He specializes in high-temperature geochemistry, isotopic geochemistry, planetary sciences, and meteoritics. His research focuses on understanding planetary formation processes, volatile element behavior in planetary interiors, and the petrogenesis of igneous rocks. Day holds a B.S. and PhD from the University of Durham, England, and has conducted fieldwork in Iceland, Mars meteorite analysis, and lunar sample studies.
Key research areas include:
- Volatiles in terrestrial planets and meteorites
- Mantle dynamics and source heterogeneity
- Martian and lunar crust-mantle interactions
- Impact processes and their geochemical signatures
Day has received major awards including the 2014 Nier Prize from the Meteoritical Society and the 2013 Houtermans Award from the European Association of Geochemistry. His work leverages advanced analytical techniques like isotopic tracing and microprobe analysis. He directs the Scripps Isotope Geochemistry Laboratory, a facility specializing in high-precision geochemical analyses.
Recent studies include investigations into the Fagradalsfjall volcanic eruption in Iceland, the geochemical composition of lunar meteorites beyond the Procellarum KREEP Terrane, and nitrogen recycling in Earth's mantle. His research bridges cosmochemistry with terrestrial magmatism, addressing fundamental questions about planet formation and evolution.
