If you are passionate about geochemistry and have taken photos that capture the ‘Wonders of Geochemistry’, enter our photo contest! Everyone is allowed to participate and you can submit up to 3 photos.
Authors of the top 3 winning photos will receive a complimentary 5-year EAG membership (worth €100), publication of their photos on the EAG website, newsletter banners and in Elements EAG pages. The photos will also be printed as post cards and available for distribution at Goldschmidt2017.
- Eiji Ohtani (Tohoku University) receives the Urey Award, recognizing outstanding contributions advancing geochemistry over a career.
- Bo Thamdrup (University of Southern Denmark) receives the Heinz Lowenstam Science Innovation Award recognizing mid-career scientists for important and innovative breakthrough in geochemistry.
- Julie Prytulak (Imperial College London) receives the Houtermans Award recognizing exceptional contributions to geochemistry by scientists within 12 years from the start of PhD.
- Shuhei Ono (Massachusetts Institute of Technology) receives the GS/EAG Paul Gast Lectureship.

Repulsion between calcite crystals and grain detachment during water–rock interaction
Y. Levenson, S. Emmanuel
Weathering in carbonate rocks is often thought to be governed by chemical dissolution. However, recent studies have shown that mechanical detachment of tiny grains contributes significantly to the overall surface retreat. Whether this detachment is caused by shear forces acting at the surface, or repulsive forces acting between grains, was not known. […]
Evidence of sub-arc mantle oxidation by sulphur and carbon
A. Rielli, A.G. Tomkins, O. Nebel, J. Brugger, B. Etschmann, R. Zhong, G.M. Yaxley, D. Paterson
The oxygen fugacity (ƒO2) of the Earth’s mantle at subduction zones exerts a primary control on the genesis of mineral deposits in the overlying magmatic arcs and on speciation of volcanic gases emitted into the atmosphere. However, the processes governing mantle ƒO2 such as the introduction of oxidised material by subduction are still unresolved. […]
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.
