You may still register for the hybrid conference Goldschmidt2022 and EAG members benefit from a $75 discount, so make sure you join or renew.
The conference is offering a wide selection of social programs throughout the week, including morning yoga, early career mixers, and more! If you are attending the conference in person, you are welcome to attend the EAG Members Reception on Wednesday 7 July at 19:30.
Diversity, Inclusion and Equity at Goldschmidt 2022
The GS and EAG recognize that diversity, equity, and inclusion (DEI) are the foundations of a strong and thriving scientific community. The DEI Committees have organized several events during the conference, including workshops and informal networking times.
EAGE-EAG Webinar "Mineral carbonation: Is it an option for the worldwide storage of CO2?" - Watch Now!
The first webinar organized by the EAGE-EAG Geochemistry Technical Community, "Mineral carbonation: Is it an option for the worldwide storage of CO2?", hosted by Alok Chaudhari and featuring guest speaker Eric H. Oelkers, took place on 22 April.
For those who missed it or who would like to watch again, the recording of the webinar is now available.
Delegates meet every ~1.5 years at the ICIW to discuss methodological development and inter-laboratory standardization, learn about exciting new applications, and share ideas. The workshops are structured around several sessions of lectures and posters, with a large portion of the time being devoted to formal and informal discussion.
Abstract submission is now open and closes on 15 July. Registration is open until 5 August and financial assistance will be available to selected students.
Many geochemists have transitioned from academia to industry, or vice-versa, during their careers. The EAG Communications Committee recently interviewed geochemists who made the move, to find out how they made the transition and to ask their advice for others in the community who may be considering a similar change. Here, we hear from Dr. Kim Nicole Dalby, Principal Scientist at Topsoe A/S.
Constant iron isotope composition of the upper continental crust over the past 3 Gyr
The Fe isotopic composition of twenty four glacial diamictite composites with depositional ages ranging from the Mesoarchean to the Palaeozoic serve as proxies of the average upper continental crust (UCC) and can be used to track how δ56Fe may have...
Neodymium isotopes trace marine provenance of Arctic sea ice
Radiogenic neodymium (Nd) isotopes (ɛNd) have the potential to serve as a geochemical tracer of the marine origin of Arctic sea ice. This capability results from pronounced ɛNd differences between the distinct marine and riverine sources, which feed...
Sulfur solubility in a deep magma ocean and implications for the deep sulfur cycle
The Earth could have experienced sulfide segregation during its differentiation due to sulfur (S) saturation within a magma ocean. The relative timing of sulfide saturation during magma ocean crystallisation is strongly dependent on the solubility of S at...
Melting experiments on Fe-C-O to 200 GPa; liquidus phase constraints on core composition
Recent theoretical calculations suggested that carbon and oxygen are important light elements in the Earth’s inner and outer core, respectively. We performed melting experiments on the Fe-C-O system and obtained ternary liquidus phase...
Perseverance: Nasa rover begins key drive to find life on Mars
[BBC] Nasa's Perseverance rover has reached a big moment in its mission on Mars. Tuesday will see the six-wheeled robot begin the climb up an ancient delta feature in the crater where it landed. It will roll uphill, stopping every so often to...
Jupiter is up to 9% Rock and Metal, Which Means it Ate a lot of Planets in its Youth
[UniverseToday] Jupiter is composed almost entirely of hydrogen and helium. The amounts of each closely conform to the theoretical quantities in the primordial solar nebula. But it also contains other heavier elements, which astronomers...
Diatoms are under threat of decline due to ocean acidification, study shows
[Phys.org] While calcifying organisms like oysters and corals have difficulty forming their shells and skeletons in more acidic seawater, diatoms have been considered less susceptible to the effects of ocean acidification—a chemical change...
[EOS] The release of carbon dioxide (CO2) during the extraction and burning of fossil fuels has contributed to major changes in Earth’s atmosphere in the centuries since humans realized their value as an energy source. Often accompanying CO2 are...
Styrofoam-munching superworms could hold key to plastic upcycling
[Phys.org] Packing material, disposable cutlery, CD cases: Polystyrene is among the most common forms of plastic, but recycling it isn't easy and the vast majority ends up in landfills or finds its way to the oceans where it threatens marine life....
Powerful platinum catalyst remains liquid at room temperature
[New Atlas] Researchers have created a form of platinum that can remain liquid at room temperature, by mixing tiny amounts of the precious metal with gallium. This new liquid platinum performs catalytic reactions more efficiently than a...
