The 2nd Bob Berner Lecture will take place at the 2018 Goldschmidt Conference in Boston. The lecturer should be a mid-career scientist who has shown exceptional ability to define globally important biogeochemical processes, has developed new understanding(s), and has significantly advanced the corresponding area of research. Find out more about the Berner Lecture.
Nomination deadline is 15 January.
Alex Hofmann is just back from Dar-es-Salaam in Tanzania, and will be travelling on to Nigeria in January for the final leg of his 2017 EAG-GS Outreach tour in Africa. Alex has been visiting universities across the continent to present a short course entitled "Early Earth Life and Mineral Systems", exploring the relationship between surface processes, evolution and habitat of life and the formation of mineral deposits on the early Earth. Find out more about the EAG & GS Outreach Program.

Conventional wisdom holds that aqueous solutions are the only non-magmatic fluids capable of concentrating metals in the Earth’s crust. The role of hydrocarbons in metal concentration is relegated to providing geochemical barriers at which the metals are reduced and immobilised. Read more

The Neoproterozoic Bitter Springs Anomaly (BSA; 810–800 Ma) is characterised by an 8 ‰ negative d13C excursion and is coeval with multiple indicators of increasing oxygenation of the ocean and atmosphere. Here, we use carbonate iodine contents to provide the first constraints on the evolution of local upper ocean redox conditions spanning the BSA. Read more

Since ultra-high pressure (UHP) minerals have been discovered in ophiolites from Tibet and the Polar Urals, it is speculated that the mantle sections of ophiolites may originate deep within the mantle. The UHP minerals are frequently found together with ultra-reduced silicides, carbides, and nitrides. Read more

The role of microorganisms in the geochemical cycle of P has received great interest in the context of enhanced biological phosphorus removal and phosphorite formation. Here, we combine scanning and transmission electron microscopies, confocal laser scanning microscopy and synchrotron-based x-ray microfluorescence to analyse the distribution of P at the oxic-anoxic interface in the water column of the ferruginous Lake Pavin.

Tin exists both under the 2+ and 4+ oxidation states in igneous systems, and thus its geochemical behaviour changes as a function of oxygen fugacity. To characterise the redox state of Sn during magmatic differentiation and how this affects its isotope composition, we have measured Sn isotopic and elemental abundances in a suite of samples from the Kilauea Iki lava lake.

[By Marco Mangayayam] Looking at minerals on a nanoscale helps us to understand their behaviour, and we can certainly learn from them for our advantage. Minerals that are highly reactive in ambient environments are not usually well understood because of difficulties in sample preparation and analysis. Read more
[By Laura Newsome] Thanks to support from the EAG I was able to attend the 2017 conference of the International Society of Subsurface Microbiology, held in Rotorua, New Zealand. Rotorua is an amazing city due to its geothermal activity. Read more
[By Mabrouk Sami] I am really grateful to the European Association of Geochemistry (EAG) for their support to attend the Conference on Accessory Minerals (CAM–2017), which took place from 13–17 September 2017 in Vienna, Austria, and Bratislava, Slovak Republic. Read more
[By Eszter Sendula] With the support of EAG, last summer I was able to attend the biennial international conference of European Current Research On Fluid Inclusions (ECROFI), organized in Nancy (France). Read more
Geochemistry making the news
[Scientific American] Thawing glaciers may speed up acidification of ocean water. Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. Read more
[Science Daily] Geophysicists uncover new evidence for an alternative style of plate tectonics. When renowned University of Toronto (U of T) geophysicist J. Tuzo Wilson cemented concepts in the emerging field of plate tectonics in the 1960s, he revolutionized the study of Earth's physical characteristics and behaviours. Read more
[Science] Spongelike crystal could make it easier for natural gas–powered cars to store fuel. As an alternative automotive fuel, natural gas, or methane, doesn't get a lot of attention. Millions of environmentally friendly, natural gas–powered vehicles cruise the world’s roads, but they still account for just a tiny fraction of new autos sold. Read more
[NASA] Scientists were already excited to learn this summer that New Horizons’ next flyby target – a Kuiper Belt object a billion miles past Pluto -- might be either peanut-shaped or even two objects orbiting one another. Now new data hints that 2014 MU69 might have orbital company: a small moon. Read more
[Science Daily] New research by Brown University geochemists provides new insights on the scale at which Earth's mantle varies in chemical composition. The findings could help scientists better understand the mixing process of mantle convection, the slow churning that drives the movement of Earth's tectonic plates. Read more
