Thank you for attending Goldschmidt2017!

The European Association of Geochemistry and the Geochemical Society wish to thank the 4630 attendees of the 27th Goldschmidt Conference in Paris last month, and are particularly grateful to all involved with the organisation of the conference.
A conference report, photos and videos of the plenary lectures are now available.
In order to keep improving the conference year after year, we strongly encourage you to share your feedback through the post-conference survey.

Contribute to EAG and help us do more

The European Association of Geochemistry firmly believes in the global availability of science. To this end, we have developed several initiatives ranging from open access community publications, support to early career scientists, or outreach programs. We’ve identified three particular initiatives where your contribution would allow us to do more:

Geochemical Perspectives Letters is moving to online format only

As announced in the preface of our last published issue of Geochemical Perspectives Letters (GPL), we will now move to an electronic format only. This move was planned at the inception of the journal and allows us to readily expand the number of manuscripts published and the speed at which we can publish without incurring additional fees. We hope this will make GPL a yet more attractive place for our community to share its latest research so please submit your next high impact manuscript to GPL.

GPL is a community journal published by the European Association of Geochemistry. It is fully society owned, open-access and carries no page charges.

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. Although the limited number of data herein impose constraints on broader generalisations, we show that microbial assemblages and organic matter (OM) composition […]

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 of a constant ⁸⁸Sr/⁸⁶Sr value in correcting for instrumental mass fractionation during analysis renders measurements ambiguous and removes information on mass-dependent fractionation variations. […]

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 known as Snowball Earths, when ice extended to tropical latitudes. Such anomalous periods of time provide unique opportunities for understanding the mechanisms regulating planetary climate and habitability. […]

Future Global Mineral Resources
Nicholas T. Arndt, Lluís Fontboté, Jeffrey W. Hedenquist, Stephen E. Kesler, John F.H. Thompson and Daniel G. Wood

In this issue of Geochemical Perspectives, six authors with wide experience in ore deposit research, exploration and production present an optimistic but realistic appraisal of future mineral resources. They describe how ore deposits form, and how they are found, assessed, mined and processed. They discuss the critical differences between mineral reserves and resources, how economic and societal factors influence supply, and the critical roles that geoscientists will continue to play. The authors argue that mineral resources will remain adequate well into the future.
