Goldschmidt2018: Register online at onsite rates
Pre-registration for Goldschmidt2018 is now closed but it is still possible to register online at the onsite rate, and if you only plan to attend for a day, one day registration is also possible. Don’t forget, EAG members benefit from the member rates. Join/renew or find your membership number in Member login.
Goldschmidt2018 is family friendly!
If your family is accompanying you to Goldschmidt2018, the conference warmly welcomes them. New this year, child care is available for the children of delegates. Learn more.
A little comic relief…
A new cartoon from the ‘Black & White?’ series, by our resident cartoonists R & B, is out now! This comic was also published in Elements June 2018 issue. Check out the full series here.

Nitrogen isotope signatures of microfossils suggest aerobic metabolism 3.0 Gyr ago
F. Delarue, F. Robert, K. Sugitani, R. Tartèse, R. Duhamel, S. Derenne
There is compelling evidence for early oxygenation of mid-Archean oceans. However, the biological use of molecular oxygen is still not ascertained. Here we report the nitrogen isotope composition measured in isolated microfossils (δ15Nµm) from the 3.0 billion years old Farrel Quartzite metasediments. […]
Mass-dependent triple oxygen isotope variations in terrestrial materials
Z.D. Sharp, J.A.G. Wostbrock, A. Pack
High precision triple oxygen isotope analyses of terrestrial materials show distinct fields and trends in Δ’17O – δ’18O space that can be explained by well understood fractionation processes. The Δ’17O – δ’18O field for meteoric waters has almost no overlap with that of rocks. […]
Toxic anthropogenic pollutants reach the deepest ocean on Earth
S. Dasgupta, X. Peng, S. Chen, J. Li, M. Du, Y.-H. Zhou, G. Zhong, H. Xu, K. Ta
Persistent organic pollutants (PCBs and PBDEs) were analysed in sediment core samples (0-2 cm) from the southern Mariana Trench at water depths of 7000-11000 m. ∑PCBs concentrations ranged from 931 to 4195 pg/g, far higher than those recorded before in marine sediments from shallower depths. […]
Cosmochemistry along the Rhine
Herbert Palme
This Geochemical Perspectives contribution traces the development of German cosmochemistry from the excitement of work on Apollo sample returns to current debates in the formation of meteorites and their components. It illuminates the crucial role played by neutron activation techniques applied at the Max Planck Institute in constraining planetary compositions and evolution. This issue further charts a fascinating collection of interlinked cosmochemical projects while providing insight into the different research environments within the Max Planck and University systems.
