Abstract submission for Goldschmidt 2026 closes in less than 10 days. Goldschmidt 2026 will bring together scientists from over 70 countries to discuss leading-edge discoveries in geochemistry and related subjects. Review the conference themes and plan to participate in Montréal or online!
World-leading experts in sustainable raw materials, the evolution of planetary bodies, contaminants in groundwater systems, the Earth’s deep interior, and nature photography will present captivating plenary lectures.
Make the most of your trip to Montréal by joining one of 24 science workshops on a wide range of subjects. They are offered on the Saturday and Sunday before the conference.
Student helpers support delegates and presenters throughout the week. The program offers free registration and the chance to meet others on the diverse, international team. Apply by 31 March.
Early Career Science Ambassador Program next deadline: 1 March
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.
Elements February issue 'Earth’s Carbon Cycle Thermostat: Beyond the Textbook Model'
Earth’s geological carbon cycle is central to both climate and life. It is generally considered to act as a “thermostat,” regulating climate and preventing global mean temperatures from fluctuating wildly. The textbook model of this regulation involves variations in solid Earth degassing rates, leading to changes in atmospheric CO2 concentrations, surface temperature, and precipitation; in turn, these modulate the rate of alkalinity production via continental silicate weathering, which changes the rate of carbonate mineral formation, thereby rebalancing the carbon cycle...
All EAG members have online access to current and past issues of Elements. Members who have selected to receive print copies of Elements, will soon receive the latest issue by post.

EAG sponsored student Juan David Solano Acosta reports back from the Nordic Geological Winter meeting 2026
[by Juan David Acosta]Participating in the NGWM26 conference was an important and timely step in my academic journey, taking place at a key moment just before my doctoral defense. As a researcher working on the geochemical and...
Nitrogen isotopic variations in the early Solar System recorded by pallasites
To gain new insights into nitrogen (N) isotopic variations in the early Solar System, N and noble gas (Ne, Ar) isotopes were measured in metal fragments and olivine separates from thirteen pallasites and five IIIAB iron meteor...
Shock origin of the largest ureilitic microdiamond: structural observations and δ13C value
We report structural evidence for impact formed diaphite or stacking disorder in the largest known extraterrestrial microdiamond (>300 μm) from the highly shocked ureilite Northwest Africa 6871. Shock indicators...
H-N budgets and isotopic signatures of Oued Chebeika 002 and CI reservoir heterogeneity
We report the hydrogen (H) and nitrogen (N) elemental and isotopic compositions of the recently recovered CI chondrite Oued Chebeika 002 (OC 002) and compare them with published data for other CI meteorites...
Kinetic Zr isotope fractionation on Mars recorded in ancient Zr-rich minerals
Zircon crystallisation induces stable Zr isotope fractionation by the preferential incorporation of the lighter Zr isotopes. The Zr isotope compositions recorded in terrestrial zircons show that, in most cases, the magnitude of...
Pyrite records fluid evolution: sulfur sources controls on arsenic speciation and zonation
Zoning and speciation of arsenic (As) in pyrite are used to infer changes in the chemical composition of hydrothermal fluids and conditions of ore deposit formation. Yet, the processes controlling the distribution and...
Tracing anatexis and bottom-up crustal homogenisation with in situ Sm-Nd isotopes
Whole rock Nd isotopes are commonly used to assess mantle-crust contributions in magma sources and to constrain the timing of magmatic and metamorphic events. However, such measurements provide limited...
Bleached Martian rocks offer fresh evidence of a wetter and warmer Mars: 'But where did they come from?
[Space.com] NASA's Perseverance rover has discovered thousands of strangely bleached rocks on Mars that are rich in a mineral difficult to form without long-term exposure to water, adding fresh evidence that the Red Planet was warmer, wetter...
The ominous sign the Gulf Stream is nearing COLLAPSE: One of the ocean's saltiest regions has become 30% less salty
[Daily Mail] One of the ocean's saltiest regions has become 30 per cent less salty – sparking fears the Gulf Stream could be inching closer to a catastrophic collapse. The southern Indian Ocean off the southwest coast of Australia has historically...
Snowball Earth was not completely frozen, new study reveals
[Science Daily] Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as once believed. New research from ancient Scottish rocks reveals that during Snowball Earth - when ice sheets...
Evolution didn’t wait long after the dinosaurs died
[Science News] In the long shadow of the asteroid that wiped out the dinosaurs, life appears to have bounced back with surprising speed. A new analysis of sedimentation rates suggests that the first wave of marine species emerged within...
Tracking global water circulation using atomic fingerprints
[Science Daily] Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called isotopes, shift in predictable...
The Mineralogical Society’s 150th Anniversary Meeting: abstract deadline 6 March
In 2026 the Mineralogical Society of the UK and Ireland will celebrate its 150th anniversary, with a special conference at the University of Manchester. The meeting will involve all of the Society’s eight special interest groups and the Mineral Deposits Studies Group. Scientists from all countries are welcome, this will be a fully hybrid conference. Remote attendance by those from low- & middle-income countries will be free of charge. Abstract submission:6 March Registration (early): 20 March - EAG members benefit from member rates

Nominations for the MinSoc, Eileen Guppy Technician’s Award: deadline 18 April
This is a new award of the Mineralogical Society of the UK & Ireland named in honour of Dr Eileen Mary Guppy (1903–1980), a geologist, petrologist & analytical chemist.
The advanced practical and technical knowledge of technicians and experimental officers is an asset to every university and research institute. To celebrate and create recognition of their contributions we are delighted to introduce the first award that specifically focusses on the contributions of technicians. Nomination/application deadline: 18 April
