Goldschmidt2019: Call for Sessions and Workshops now open

Barcelona is the next destination of the Goldschmidt Conference and we warmly invite you to come and actively participate in the conference, starting with building a high quality science program.

The Call for Session and Workshop proposals is now open. Visit the Goldschmidt2019 website for more information and instructions on how to submit your proposals.

The deadline for both calls is 1 November 2018.

2019 Award Nominations

Recognition of scientific excellence at all stages of one’s career is crucial. Should you know of any deserving colleagues, nominate them for an EAG Award, the Geochemistry Fellowship or the R. Berner Lecture. Information and instructions on how to submit a nomination are available here.

Deadline for GS/EAG Fellows nominations: 31 October
Deadline for EAG Award nominations: 15 November

Post-Goldschmidt2018

G18_logo_100The Geochemical Society and the European Association of Geochemistry are honoured to have hosted the 28th Goldschmidt Conference in Boston! Goldschmidt was once again a successful conference, thanks to the efforts and dedication of all the volunteers involved.
We invite you to watch videos of the plenary talks and the pop-up talks through the Goldschmidt YouTube Channel. You can also view all the photos of the conference!

GPL1822_abstractInfluence of metasomatism on vanadium-based redox proxies for mantle peridotite
A.B. Woodland, L. Uenver-Thiele, H.-M. Seitz

The multi-valence nature of vanadium means that its geochemical behaviour will be ƒO2-dependent, so that its concentration or V/Sc (or V/Ga), can serve as proxies for oxidation state in mantle peridotites. Compared to Fe3+/Fe2+-based equilibria, such trace elements may be less sensitive to metasomatic processes. […]

GPL1819_abstract_100Apollo 15 green glass He-Ne-Ar signatures – In search for indigenous lunar noble gases
E. Füri, L. Zimmermann, A.E. Saal

Identifying indigenous lunar noble gases in samples returned by the Apollo and Luna missions is highly challenging because contributions from the solar wind (SW) and/or cosmogenic nuclides have modified the noble gas signature of the regolith and rocks exposed to space at the lunar surface. […]

GPL1818_abstract_100Hadean geodynamics inferred from time-varying 142Nd/144Nd in the early Earth rock record
N.S. Saji, K. Larsen, D. Wielandt, M. Schiller, M.M. Costa, M.J. Whitehouse, M.T. Rosing M. Bizzarro

Tracking the secular evolution of 142Nd/144Nd anomalies is important towards understanding the crust-mantle dynamics in the early Earth. Excessive scatter in the published data, however, precludes identifying the fine structure of 142Nd/144Nd evolution as the expected variability is on the order of few parts per million. […]

commentandreply_100Comment 2 on “Ultra-high pressure and ultra-reduced minerals in ophiolites may form by lightning strikes”
J.S. Yang, R.B. Trumbull, P.T. Robinson, F.H. Xiong, D.Y. Lian

We read with great interest the paper by Ballhaus and coauthors (2017) reporting on electrical discharge experiments that showed how SiC and other phases found in mantle-derived rocks can potentially form by lightning strikes (Ballhaus et al., 2017). The experiments are technically innovative and challenging and the results make fascinating reading. […]

Reply 2 to comment on “Ultra-high pressure and ultra-reduced minerals in ophiolites may form by lightning strikes”
C. Ballhaus, H. Blanchard, R.O.C. Fonseca, A. Bragagni

We appreciate the comments by Yang et al. (2018) to our recent proposal (Ballhaus et al., 2017) that high pressure and ultra-reduced minerals in ophiolites may form by lightning strikes. We have carried out additional experiments to address the issues raised by Yang et al. (2018). […]

v7n1_cover_100Cosmochemistry 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.
