The early registration and presenter registration deadline is 21 May.
Along with your registration you can also sign up for the Mentor Program, for a pre-conference science workshop, or for early career workshops. The booking deadline is 21 May. Space is limited so book early!
Whether you are a first-time attendee or a more experienced conference-goer, if you are interested in sharing some of your experiences at Goldschmidt on the EAG Blog, we'd love to have you on board. A free ticket for the Early Career Mixer will be offered to each of our bloggers. Contact the EAG Office to find out more.
Warning: accommodation scam!
The conference does NOT use any travel agency, so if you are contacted by an organisation claiming an affiliation with the conference, be careful as that this is a scam. Delegates should book their accommodation directly themselves. See Venue & Travel for more information.
New Geochemical Perspectives 'The Evolution of Atmospheric Composition and Climate: Why Earth is a Habitable Planet'
This the 30th Geochemical Perspectives issue, by James Kasting covers the long-term evolution of Earth’s atmosphere and climate, with a particular focus on the rise of O2 and the faint young Sun problem. What we think we understand about Earth’s atmosphere/climate history is then used as a guide to speculate on whether Earth-like planets might exist around other nearby stars.
Geochemical Perspectives is an open access community journal published by the European Association of Geochemistry. EAG members who opted to receive a print copy will receive it soon.
Expression of support for fellow American Scientific Societies
TheEuropean Geosciences Union has issued a support statement for our fellow American scientific societies, and the European Association of Geochemistry has endorsed it.
Social media: EAG leaves X, follow us on Bluesky, Facebook or LinkedIn
The EAG has decided to stop its presence on the platform X (formerly Twitter) and @EAG_ has been discontinued. You can follow us on Bluesky, Facebook and now also on LinkedIn.
Next EAG Sponsored Student deadline: 1 May
The EAG Student Sponsorship Programsupports onsite participation at events held in Europe, or online participation at events held anywhere in the world. Successful applicants will receive sponsorship of up to 1000 euros to cover registration, abstract fees, and travel expenses where applicable. Applicants may be based in any country.
All EAG members have online access to current and past issues of Elements. Members who have selected to receive print copies of Elements, will shortly receive the latest issue by post.

From Rocks to Revelations: EAG sponsored student Cendi Dana, research visit to ETH Zurich
[by Cendi Dana] Nestled in the heart of Switzerland, ETH Zurich stands as a global leader in Earth Sciences. From March 10th to 14th, 2025 I had the privilege of visiting this renowned institution to conduct high-precision U-Pb geochronology analysis on...
Formation of abnormally high density H2S fluid in sedimentary basins
Mississippi Valley-type (MVT) deposits serve as important sources of lead-zinc metals, requiring abundant reduced sulfur for their formation. High density H2S fluids greatly influence the efficiency and scale of...
Lengthening of biogeochemical processes during winter in degraded permafrost soils
The consequences of permafrost thaw for organic carbon release are mainly studied in summer, considering the frozen soil is inert in winter. Here, we show that biogeochemical processes also occur during early winter...
The Martian isotopic record displays a dichotomy in volatile compositions. Interior volatiles from the mantle record a chondritic heritage (e.g., H, N, Kr, Xe) whereas the atmospheric reservoir of Kr and Xe – which...
