Goldschmidt Conferences

Goldschmidt 2026: Call for sessions and workshops open

We invite the entire geochemistry community to submit suggestions for sessions and workshops to help create another great Goldschmidt conference.

Review the list of themes to determine the best one for your proposed session. Sessions should aim to attract at least 25-30 abstract submissions.

We welcome proposals for workshops to be held in Montréal before the conference. Learn more about organizing a workshop.

The deadline for proposals is 15 October.

Changes to nominations for 2026 awards

Nominations for the 2026 Awards are open until 30 October. There have been some changes to the nomination process and guidelines, explained below.

The H.C. Urey Award recognizes scientists who have made outstanding contributions advancing geochemistry over a career. Significant changes were made to the nomination process; in particular, there are no more nomination letters.

The Science Innovation Award recognizes scientists who have recently made a particularly important and innovative breakthrough in geochemistry. There are new eligibility criteria: nominees must have received a recognized doctorate within 25 years of the first day of the year in which the award is given (career breaks are taken into account).

The F.G. Houtermans Award recognizes exceptional contributions to geochemistry by an early career scientist. There are new eligibility criteria: nominees must have received a recognized doctorate within 7 years of the first day of the year in which the award is given (career breaks are taken into account).

The Geochemistry Fellowship honors outstanding scientists who have made major contributions to the field of geochemistry. The award is based on scientific excellence as well as the broader impacts candidates have made in their careers to date.

EAG Early Career Science Ambassador deadline 1 October

This program provides funding to Early Career Scientists based in Europe who wish to attend conferences outside Europe, and to Early Career Scientists in any country who plan to attend a fully virtual or hybrid conference remotely. Supported scientists attending a conference in person will have 50% of their expenses covered by EAG, up to 1500 Euros.

Next application deadline: 1 October

Outreach Program

As part of the EAG-GS Outreach Program, Julio Sepúlveda (University of Colorado Bolder) will visit University of Antofagasta (Chile) on 7 October, and Universidad Tecnológica de Panamá on 17 November.

Organising a short course or conference in Europe in 2026? Apply for EAG Sponsorship by 1 November

The EAG Short Course and Conference Sponsorship Program is open to EAG members organizing a short course or small conference in Europe focused on special topics or techniques from the broad field of geochemistry. The program aims to directly support student attendance at the event.

For events taking place in 2026, the application deadline is 1 November 2025.

Applications for online as well as hybrid and in-person events will be considered.

Advances in Geochemistry and Cosmochemistry publishes its first articles

Advances in Geochemistry and Cosmochemistry (AGC) has published its first research articles since its opening for submission earlier this year. AGC is a community led and run diamond open access journal (free to read and free to publish). More information about the journal, article types and submission requirements can be found on their submission page.

Eclogite xenoliths record a constant ocean oxygen isotope composition for 3 billion years

In this work, we utilised the triple oxygen isotope (TOI) composition of Archean-age xenolithic eclogites, representative of Archean subducted altered oceanic crust (AOC) to constrain the triple oxygen isotope...

Stable strontium isotopes reveal magma-fluid interaction during the evolution of granitic magma

The interaction between granitic magma and fluid at convergent plate margins plays a key role in crustal differentiation and rare metal mineralisation. However, this process remains poorly understood due to the elusive nature...

Mercury isotopes in North Pacific sediments reveal vegetation expansion in warm climates

Mercury (Hg) concentrations and isotope compositions in sedimentary rocks are widely used to trace volcanism, but their natural variabilities through climate changes remain to be fully understood. Here, we present Hg...

High field strength elements in chondrites and their refractory components

In geochemistry and cosmochemistry, chondrites provide important reference values for comparison with planetary compositions. Employing isotope dilution, we report a comprehensive high precision data set for...

Impact of wildfires on Gondwanan flora during the Permian–Triassic transition

The Permian–Triassic (P/T) transition is a critical juncture in Earth’s history. Rock sequences from this interval record a significant loss of biodiversity in marine environments, a reduction of terrestrial...

Fe(II)aq-induced transformation of Fe-rich precipitates from a hydrothermal field

Aqueous ferrous iron (Fe(II)aq) is known to induce recrystallisation of Fe(III) oxyhydroxides, yet the relevance and implications of this process in low temperature hydrothermal systems remain underexplored...

Water storage in the refractory lithospheric mantle

This study reveals that ophiolitic olivine contains water, ranging from several to 170 μg.g−1, contradicting expectations of a depleted refractory mantle. This range is comparable to xenolithic olivine from the...
