Goldschmidt2019: Field-trips, workshops and registration
Preparations are full swing for Goldschmidt2019 in Barcelona and once again numerous pre- and post-conference field trips and teaching and networking workshops have been organised. Spaces are limited, so be sure to reserve your places quickly.
Register online for Goldschmidt2019 by June 18 to take advantage of the early registration rates. EAG members benefit from the member rates.
A family friendly Goldschmidt
The conference welcomes the families of its delegates. For those coming to Barcelona with their children, subsidised childcare will be provided onsite, with a full program of activities for 6-month to 12-year-olds. Places must be reserved in advance and space is limited to 20 places per session, so be sure to book early. Find out more here.
Q&A with Goldschmidt Panellist: Lewis Collins
In a new initiative for Goldschmidt2019, a series of lunchtime discussion forums will be held to give students and post-docs the opportunity to find out more about pursuing careers outside of academia.
Panellist Lewis Collins, Editor-in-Chief of the journal One Earth, talked to us about his job and the path he took into the world of scientific publishing. Read the full interview here.
EAG Student Sponsorship: next deadline – 1 May
The EAG Student Sponsorship Program sponsors 12 students each year, up to 500 Euros per student, to attend geochemistry-related short courses, summer schools, workshops or conferences located in Europe (except for the Goldschmidt conference). The next application deadline is 1 May 2019.

Exchange catalysis during anaerobic methanotrophy revealed by 12CH2D2 and 13CH3D in methane
J.L. Ash, M. Egger, T. Treude, I. Kohl, B. Cragg, R.J. Parkes, C.P. Slomp, B. Sherwood Lollar, E.D. Young
The anaerobic oxidation of methane (AOM) is a crucial component of the methane cycle, but quantifying its role in situ under dynamic environmental conditions remains challenging. We use sediment samples collected during IODP Expedition 347 to the Baltic Sea to show that relative abundances of 12CH2D2 and 13CH3D in methane remaining […]
Thermodynamic controls on redox-driven kinetic stable isotope fractionation
C. Joe-Wong, K.L. Weaver, S.T. Brown, K. Maher
Stable isotope fractionation arising from redox reactions has the potential to illuminate the oxygenation of Earth’s interior, oceans, and atmosphere. However, reconstruction of past and present redox conditions from stable isotope signatures is complicated by variable fractionations associated with different reduction pathways. Here we demonstrate […]
Onset of new, progressive crustal growth in the central Slave craton at 3.55 Ga
J.R. Reimink, D.G. Pearson, S.B. Shirey, R.W. Carlson, J.W.F. Ketchum
Ancient rock samples are limited, hindering the investigation of the processes operative on the Earth early in its history. Here we present a detailed study of well-exposed crustal remnants in the central Slave craton that formed over a 1 billion year magmatic history. The tonalitic-granodioritic gneisses analysed here are broadly comparable to […]
A lunar hygrometer based on plagioclase-melt partitioning of water
Y.H. Lin, H. Hui, Y. Li, Y. Xu, W. van Westrenen
The Moon was initially covered by a magma ocean. Hydrogen detected in plagioclase of ferroan anorthosites, the only available samples directly crystallised from the lunar magma ocean (LMO), can be used to quantify LMO hydrogen content. We performed experiments to determine plagioclase-melt partition coefficients of water under […]
Big Picture Geochemistry from Microanalyses – My Four-Decade Odyssey in SIMS
Nobumichi Shimizu
In this new Geochemical Perspectives, Nobumichi Shimizu recounts his personal story of how the ion microprobe became a powerful tool in geochemistry and how in situ trace element and isotope analysis techniques have been used in various ways in solid earth geochemistry. This is also the story of how micro-scale observations changed, and continue to change, our views on large-scale natural phenomena.
