JASON dive today reached 6500 m. The deepest JASON has dived. We collected over 30 samples of peridotite and gabbro. 👏

Plagioclase peridotite from the Mariana Trench- a Rosetta Stone for decoding thermal history and oxygen fugacity conditions in the mantle

Congratulations to Jesse Scholpp, who successfully defended his dissertation on Friday! Jesse is going on to a postdoc with Dr. Simon Jowitt at College of Science at the Uni. of Nevada, Reno Cheers Jesse! Dept. of Earth, Environmental & Planetary Sciences

Mt Rainier from White Pass! Hope everyone is having a wonderful holiday 😄

A lovely snow day in Knoxville 😎

Did you catch the updates last semester about Dr. Nick Dygert and his students going to Mariana's Trench? Now they're hard at work preparing those samples for analyses that will tell us more about our planet's story. #FlashbackFriday

Model rockets- anyone else build them as a kid? Fun passing along the tradition

A Eu-based plag-cpx oxybarometer for cumulate rocks, now published in GCA! also: divalent element cpx-melt partitioning model T-X-fO2-dependent cpx-melt Eu partitioning model Thx 2 coauthors Dian Ji & Emily Etheridge 4 contributions! authors.elsevier.com/a/1kn8S3p4Zc5W1 Dept. of Earth, Environmental & Planetary Sciences

PhD student Emily Etheridge talks about her work on thermal histories of aubrite meteorites #LPSC2025 Aubrites r cool because they have the same O isotopic composition as Earth, suggesting they condensed from the same part of the solar nebula, but have very different mineralogy

Interested in the moon and space exploration? 🌔☄️Join EEPS Professor Dr. Nick Dygert and University of Tennessee Nuclear Engineering Professor Dr. Lawrence Heilbronn for a lunchtime seminar TOMORROW, April 22 at 12:30 in Strong Hal 611. UT Arts & Sciences

Last week we celebrated the incredible accomplishments of undergraduate students, graduate students, and faculty in our department for their incredible service, research, teaching, and growth this year. We're proud of all of you! UT Arts & Sciences

Breakaway Bluff on the The Cumberland Trail in Obed backcountry. Can you hear the cicadas? 14 miles, deer, bears, turtles, an engorged snake, magnolia and mountain laurel blooms, blueberries, enough chanterelles to season my grits, 4 swimming holes and no other humans 😎

On a family vacation in Portugal and I’m enjoying the Moorish-influenced decorative art. So many elements of symmetry. These will be fun to show in the crystallography unit of my #mineralogy class

How fast does the mantle cool beneath spreading centers, and why does it vary among localities & tectonic settings? A new analysis doi.org/10.1016/j.lith… in the Oman DrillingProject special issue of Lithos: sciencedirect.com/science/journa… Dept. of Earth, Environmental & Planetary Sciences

Bummed around Poland before #goldschmidt2025, these are the high Tatras, a granitic subrange of the Carpathians. Pretty spectacular!
