The Goldschmidt Conference has become the most important forum for the discussion of recent results in geochemistry and related fields, and we hope to maintain that tradition with another excellent program in 2018. The science committee and theme leaders have identified 14 broad themes, and the entire geochemistry community is now invited to submit suggestions for sessions through November 1. Get started by reviewing the submission instructions.
Recognition of scientific excellence at all stages of one's career is crucial. Should you know of deserving colleagues, nominate them for an EAG Award or GS/EAG Fellowship. We also provide guidance on how to write a nomination and support letter.
GS-EAG Geochemical Fellowship: recognizes scientists who have made major contributions to the field of geochemistry. Nomnination deadline is 31 October.
Urey Award: recognizes scientific excellence over a career. Nomnination deadline is 15 November.
Science Innovation Award (named after Nicholas Shackleton for his work in climatology): recognizes scientists within 30 years from the start of PhD. Nomnination deadline is 15 November.
Houtermans Award: recognizes scientists within 12 years from the start of PhD. Nomnination deadline is 15 November.
Berner Lecture Award: recognizes mid-career scientists. Nomination deadline is 15 November.
The Council Elections 2018 are now open and EAG members are asked to select 2 candidates out of 4. Councillors participate in council discussions, decisions, initiatives and act as ambassadors of the society. They are therefore crucial for determining the strategy and the future of the EAG.
Yesterday, EAG members received a personalised link to vote. If you haven't received yours, please contact the EAG Office.
Mineral resources are a vital part of any economy, modern or ancient. Since the birth of civilization, man has used these resources for pigments, metals, glasses, ceramics, cements and much more. The media has recently suggested there is a crisis looming over finding mineral resources, including critical metals. Read more
EAG members will receive their print copy shortly and have online access to all back issues of Elements (user id = email address, password = EAG membership number). To find your membership number, login to your member area.
In line with fulfilling the aim of making science available to all, each year, the EAG Distinguished Lecture Program funds an eminent geochemist to give lectures in several institutions in Eastern Europe. This year's lecturer, Lenny Winkel (ETH Zürich) will be visiting institutions in Hungary, Romania and Czech Republic, from 20 to 26 October. Lectures are open to all. See tour information.
If you are an EAG member and are organising a short course or small conference in Europe in 2018, you can apply for EAG Sponsorship. Short courses or small conferences should have at least 10 participants and focus on special topics or techniques from the broad field of geochemistry. EAG sponsorship directly supports students attending.
Climate driven carbon and microbial signatures through the last ice age
J. D’Andrilli, H.J. Smith, M. Dieser, C.M. Foreman
Ice cores preserve diverse materials as millennial-scale proxies for Earth’s history. While major ions and elemental analyses are commonly investigated in palaeoclimate reconstructions, the integration of biological measurements is rapidly developing. [...]
Stable strontium isotopic heterogeneity in the solar system from double-spike data
B.L.A. Charlier, I.J. Parkinson, K.W. Burton, M.M. Grady, C.J.N. Wilson, E.G.C. Smith
Strontium isotopic anomalies in meteorites are important in assessing nucleosynthetic sources to, and measuring the timing of, early solar system processes. However, conventional use [...]
Running out of gas: Zircon 18O-Hf-U/Pb evidence for Snowball Earth preconditioned by low degassing
J. Hartmann, G. Li, A.J. West
The general long-term stability of Earth’s climate over geologic time was punctuated by dramatic excursions. Between ca. 2.5 and 0.5 billion years ago (Ga), these events included the globally extensive glaciations [...]
The gravitas of gravitational isotope fractionation revealed in an isolated aquifer
T. Giunta, O. Devauchelle, M. Ader, R. Locke, P. Louvat, M. Bonifacie, F. Métivier, P. Agrinier
Despite the ubiquitous effects of gravitation on Earth, its potential influence on relative distribution of isotopic substances has remained elusive – and so far only identified in confined gaseous systems (Craig et al., 1988; Severinghaus et al., 1996, 1998). [...]
Magma dynamics of ancient Mt. Etna inferred from clinopyroxene isotopic and trace element systematics
S.A. Miller, M. Myers, M.F. Fahnestock, J. Bryce, J. Blichert-Toft
Dynamic magmatic processes driving volcanic eruptions, including melting, fractionation, and assimilation, provide critical insights into plumbing systems supporting long-lived magmatism.
The solubility of heat-producing elements in Earth’s core
I. Blanchard, J. Siebert, S. Borensztajn, J. Badro
The long term thermal and dynamic evolution of Earth’s core depends on its energy budget, and models have shown that radioactive decay due to K and U disintegration can contribute significantly to core dynamics [...]
The EAG Communications Committee asked 6 questions to Rob Raiswell, Emeritus Professor at the School of Earth and Environment in Leeds University. Rob Raiswell co-authored with Don Canfield the first Geochemical Perspectives issue, ‘The Iron Biogeochemical Cycle Past and Present’, and he is regularly involved with creating the EAG cartoons ‘Black & White’.

[By Thomas Belgrano] am extremely grateful for the support of the European Association of Geochemistry (EAG) for contributing to my attendance at the 14th SGA Biennial Meeting in Québec city as an Early Career Science Ambassador. Quebec City was a great host, where North American traditions collide with French ones in a surprisingly harmonious way. Read more
Geochemistry making the news
[Scientific American] Earth's moon doesn't have much of an atmosphere today. However, it may have had a more prominent atmosphere 3 billion to 4 billion years ago, when volcanic eruptions spewed giant clouds of gas above the lunar surface, a new study has found. Read more
[Scientific American] Tropical forests are adding more carbon dioxide to the atmosphere than they're removing, according to a new study that estimates the world's lush canopies emit more CO2 than all of America's cars and trucks. Read more
[BBC Earth] Throughout history, humans have existed side-by-side with bacteria and viruses. From the bubonic plague to smallpox, we have evolved to resist them, and in response they have developed new ways of infecting us. Read more
[The Guardian] Life may have gained a foothold on Earth more than 4bn years ago, according to researchers who believe that fragments of carbon found in rocks in Canada are remnants of ancient organisms. Read more
[Climate Central] The list of environmental problems that the world faces may be huge, but some strategies for solving them are remarkably small. First explored for applications in microscopy and computing, nanomaterials — materials made up of units that are each thousands of times smaller than the thickness of a human hair Read more
The Geochemistry Group of our partner society the Mineralogical Society offers funding opportunities that aim to promote and support geochemistry-related research within Great Britain and Ireland. The latest application round for supporting student travel to meetings/conferences is open until 15 October. See details.
The International Association of Geochemistry are accepting applications for the IAGC PhD Student Research Grants, sponsored by Elsevier and the IAGC. Students can request up to $3,000 for geochemical analyses in support of their PhD research. Proposals are due 1 December and funds will be dispersed to winning applicants on or before 1 May of 2018.
