Our paper, led by Duncan Keller, on anorthosites is out in Science Advances. Anorthosites are mysterious rocks. Massive accumulations of feldspar. The big ones are only found on Earth around 1 - 1.7 billion years ago. The only other place we get them is on the moon, where they

The department of Earth, Environmental and Planetary Sciences Rice Earth, Environmental and Planetary Sciences, Rice Natural Sciences has opened its Pan post-doctoral fellowship competition for this year. Help us spread the word to the potential candidates. 🌋🌕🌎🪐☄️ eeps.rice.edu/eeps-job-oppor…

🚀 Exciting PhD & Postdoc Opportunities! 🚀 My group at Rice University is recruiting PhD students and postdocs for 2025. Join us to explore space and dive into cutting-edge cosmochemical research! Please consider applying or spreading the word. My NASA-funded programs focus on

Jackson Borchardt @jsborchardt and my paper on Cl systematics in arc magmas just came out. We use amphiboles to reconstruct pre-eruptive Cl contents of arc magmas. We show, perhaps not surprisingly, that Cl behaves as an incompatible element and thus becomes progressively

How did S inventory evolve in the lunar mantle? - Tomorrow (Friday) morning Board 3015 at #AGU24, I'll present a new model designed with Rajdeep Dasgupta for lunar fO2, that can calculate the S solubility of silicate melts in equilibrium with sulfides of different metal/sulfur.

Where is sulfur (S) in the Earth's mantle? Sulfides of course! But can silicate minerals store some S during mantle melting? Can we measure trace S in silicates using EPMA? Rice Earth, Environmental and Planetary Sciences Rice Natural Sciences PhD student Anna Johnson's recent paper has some answers.🌋

Climate change plays a role in priming conditions for fires, but this treats the problem too simplistically, especially considering what actually triggered the fires. Quoting from a paper by Keeley in 2021 on Santa Ana Wind (SAW) fires: “In the southern California region, 100%

What is the origin of the young Chang’e-5 mare basalts? -Tomorrow (Monday) at 2:50 in the #LPSC2025 Waterway 1, I'll present a joint study with Rajdeep Dasgupta that reveals the presence of garnet in the young lunar mantle, as a consequence of lunar cumulate mantle overturn.

Tomorrow at 8:55, waterway 5, I will talk about our recent work about at what conditions the farside mantle melted to generate the surface lavas of South Pole-Aitken basin #LPSC2025

🚨 News Flash 🚨 Dr. Rajdeep Dasgupta was featured in the Wiess School of Natural Sciences March 2025 newsletter. His research involves replicating inner Earth conditions to "uncover the secrets of our planet's internal processes." #EEPS #GeoScience #CarbonCycle #RiceNatSci

Where and how the lavas in lunar farside South Pole were generated? In this work led by Rice Earth, Environmental and Planetary Sciences, together with Rajdeep Dasgupta Dian Ji Cin-Ty Lee and collaborators, we explore the possibilities with a petrological approach 1/5 agupubs.onlinelibrary.wiley.com/doi/full/10.10…

Want to know the lunar S evolution from Apollo to Chang’e-5 mantle? Check out our new GCA paper with Rajdeep Dasgupta! A new sulfur content at sulfide saturation (SCSS) model is also attached that is suitable for sulfides with variable metal-sulfur ratio. doi.org/10.1016/j.gca.…
