The effects of sulfur on near-liquidus phase relations of highly reduced basaltic melts with implications for magmatism in Mercury
Data returned from NASA’s MESSENGER mission reveal that Mercury’s surface is highly enriched in sulfur (S) and depleted in iron (Fe), consistent with …

Check out our new GCA paper, for the first time we are looking at S bonding in silicate melts with first principles simulations! The results are applicable to S rich magmatic system like #Mercury!

AI is killing part of the science. Reviewing used to be enjoyable and a way to learn. Now I spend too much time reviewing AI generated papers. I wonder if the authors even understand what they’ve written. It even sounds hilarious that if AI review AI written papers.

What powered the Moon's late-stage volcanism? 🌙🌋
Our experiments & modeling published in EPSL with Rajdeep Dasgupta show garnet in the young lunar mantle, pointing to deep fertile material by mantle overturn or prolonged mantle convection.

We have a new paper. This one is about generating highly differentiated, low F melts through a series of interconnected magma chambers, each undergoing only moderate crystallization (moderate F), with the effects compounding after each successive staging.

Oxygen fugacity is so confusing in geology but is quite appealing in atmosphere chemistry, here the definition of oxygen fugacity as the partial pressure of oxygen makes more sense and is measurable with a sensor that responds to the voltage.

![[alt text by NASA] The Moon, seen here backlit by the Sun during a solar eclipse on April 6, 2026, is photographed by one of the cameras on the Orion spacecraft’s solar array wings. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk. The bright spot visible just below the Moon’s bottom right edge is Saturn. Beyond that, the bright spot at the right edge of the image is Mars.

New work challenges the idea of a “wet” Moon🌙💧
Our GCA study, with Raj and @cintylee.bsky.social, shows water-rich lunar melt inclusions form via magmatic recharge, instead of requiring a wet mantle! The Moon may still be strongly volatile-depleted. @riceeeps.bsky.social
