In preparation of Goldschmidt2017 (13-18 August 2017), the whole geochemistry community is invited to submit suggestions for sessions before 1 November. Please note that any suggested sessions must be broad enough to attract at least 25 abstract submissions.
If you are interested in organising a pre-conference workshop or Town Hall meeting, you are also invited to submit a proposal before 1 November. Find out more.
What does it change to receive an award? Read testimonies from recent medallists.
Should you know of deserving colleagues, now is the time to nominate them.
Deadline for GS/EAG Fellowship nominations is 31 October.
Deadline for EAG Urey and Houtermans Awards nominations is 15 November.
Deadline for Lowenstam Science Innovation Award nominations is 15 December.
We also provide guidance on how to write a nomination and support letter.
The Council Elections 2017 are now open and EAG members are asked to select 3 candidates out of 6. 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. Earlier this month, EAG members received a personalised link to vote. If you haven’t received yours, please contact the EAG Office.
We are very happy to report that the 2016 Distinguished Lecture Program is now finalised. Prof. Alexandre Anesio, 2016 Distinguished Lecturer, will provide lectures on biogeochemistry in institutions in Ukraine, Romania, Slovenia and Poland from 21 to 28 October.
If you are located in one of these institutions (or a nearby one), you are invited to attend as the lectures are open to all.
After Paris in 2017, the Goldschmidt2018 will take place in Boston (USA), 12-17 August 2018, and Goldschmidt2019 in Barcelona (Spain), 18-23 August 2019. So mark your calendar!
The Goldschmidt conference is organised by the European Association of Geochemistry on odd-numbered years and by the Geochemical Society on even-numbered years.

Thoughts and Reminiscences on Experimental Trace Element Partitioning
John H. Jones (NASA Johnson Space Center)
In this issue, John Jones reviews the history of experimental trace element partitioning from his personal point of view. In so doing, he considers experimental and analytical complexities, simple phase equilibria, and thermodynamic considerations. Jones also recounts personal interactions with other geochemists and petrologists.
Pressure-induced ion pairing in MgSO4 solutions: Implications for the oceans of icy worlds
C. Schmidt, C.E. Manning
At ambient temperature, liquid water transforms from a low-density to a high-density dynamic structure at ~0.2 GPa. The transition persists in electrolyte solutions; however, its effects on solute properties are unknown. […]
Warm Archean oceans reconstructed from oxygen isotope composition of early-life remnants
R. Tartèse, M. Chaussidon, A. Gurenko, F. Delarue, F. Robert
Deciphering the surface conditions on the Earth during Archean times (> 2.5 billion years ago – Ga) is crucial to constrain the conditions that promoted the development of life. The progressive shift through time of the oxygen isotopic compositions of Precambrian siliceous sediments – the so-called cherts – has been interpreted as indicating a secular decrease of seawater temperature by 50-80 °C from the early Archean to the present-day. […]
The 176Lu-176Hf systematics of ALM-A: A sample of the recent Almahata Sitta meteorite fall
R. Bast, E.E. Scherer, A. Bischoff
The application of Lu-Hf chronometry to meteorites has been compromised by arbitrary results such as dates up to 300 Myr older than the Pb-Pb age of the Solar System, unsubstantiated isochron scatter among different meteorite fractions, and varying initial Hf isotope ratios (176Hf/177Hfi). […]
Cadmium isotope variations in Neoproterozoic carbonates – A tracer of biologic production?
S.V. Hohl, S.J.G. Galer, A. Gamper, H. Becker
Cadmium concentrations and stable isotopic compositions in seawater are important tools for studying the biogeochemical cycling of Cd in the modern oceans and as a proxy for micronutrient utilisation by phytoplankton. It is now well established that Cd isotopes become “heavier” as the primary production in the surface ocean increases, even though the mechanism driving the isotopic fractionation is still debated.
