Community survey for a new Diamond Open Access Journal in Geochemistry
A group of geochemists is taking the first steps towards building a new Diamond Open Access Journal in Geochemistry (free to publish and free to read). A community survey has been launched by the group to gather feedback to shape the design of the journal. Click on the button below for more information and to take part. Close of survey: 15 June.
Alkaline lakes are incredibly dynamic, unique, and fascinating biogeochemical environments. This thematic issue leverages the authors’ multidisciplinary insights to portray alkaline lakes’ biogeochemical, mineralogical, and geological importance for both science and society. The articles individually explore the unique conditions leading to the formation of alkaline lakes, the distinctively productive microbial ecosystems that inhabit them, their distinguishing chemistry and mineralogy, their role as societally important economic resources....

Shipboard Science but with less shaky legs – The ECORD Training Course 2023
[By Katrin Wagner] I am hopeful to one day join an IODP expedition as an inorganic geochemist, and so I travelled to Bremen, Germany in March 2023 to participate in the “ECORD Training Course” with the support of the EAG. The course is a so-called shipboard simulation, in which...
A scientific party of SIMS experts and enthusiasts at the GFZ Helmholtz Centre, Potsdam
[By Abimbola Chris Ogunyele] As a young analytical geochemist, I am always fascinated and interested in learning the basics, applications and technical know-how of different instruments and method. Here I describe my experiences as an EAG sponsored student on a SIMS...
Lakes as Memories of the Landscape: EAG Early Career Ambassadors report back
[By Allix Baxter and Ronald Lloren] We are grateful for the opportunity to have represented the EAG as Early Career Ambassadors at the recently concluded joint meeting of the International Association of Limnogeology and the International Paleolimnology Association (IAL-IPA) last November 2022...
The magma ocean was a huge helium reservoir in the early Earth
Helium from mantle-derived rocks bears in its isotopic ratios the traces of Earth differentiation, degassing, and long term geodynamic evolution. The low 4He/3He ratio of rocks whose origins are in the deep...
Geobarometric evidence for a LM/TZ origin of CaSiO3 in a sublithospheric diamond
Breyite is the second most abundant mineral inclusion in super-deep diamonds after ferropericlase. Though breyite stability extends to 300 km along typical mantle geotherm, this phase is often assumed to be the...
Global patterns of radiocarbon depletion in subsoil linked to rock-derived organic carbon
Organic matter stored in sedimentary rocks is one of the largest stocks of carbon at Earth’s surface. The fate of this rock organic carbon (OCpetro) during weathering in soils influences the geological carbon cycle...
The chemical conditions necessary for the formation of microbialites
Whether biological and/or physico-chemical variations may have changed the abundance of microbialites over geological times remains debated. This calls for a better appraisal of the conditions necessary for the formation...
The Six Moons Most Likely to Host Life in Our Solar System
[Scientific American] In 2005 the Cassini spacecraft visiting Saturn flew through something engineers didn’t expect—a fine water mist, spraying into space at 1,290 kilometers per hour through cracks in the surface of Saturn’s tiny...
Subsurface microbes capture toxic uranium and remediate groundwater
[Phys.org] A new research study describes a previously unknown chemical process for removal of uranium from groundwater. Deep down in the bedrock, in an oxygen-free environment, microbes assist in the process of...
Dark Clouds on the Horizon – The Most Accurate Measurements Yet of Black Carbon
[SciTechDaily] Our industrialized civilization contributes a broad array of pollutants to the environment. A significant source of these pollutants is combustion, which leads to the production of aerosol particles, including black carbon....
A theory to explain why helium-3 is leaking from Earth's core
[Phys.org] Two geoscientists have developed a theory to explain how helium-3 leaks from the Earth's core into the mantle. In their study, Jie Deng and Zhixue Du used first-principle calculations to show that helium-3 could enter magnesium oxide...
Greenhouse gas release from permafrost is influenced by mineral binding processes [Press Release]
[University of Cologne] About a quarter of the organic carbon contained in ice-rich Arctic permafrost is more difficult for microorganisms to utilize. The reason for this is a strong binding of the organic material originating from dead plant...
A Stormy, Active Sun May Have Kickstarted Life on Earth [Press Release]
[NASA Goddard] The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth’s early atmosphere...
How Desert Dust Nourishes the Growth of Phytoplankton at Sea [Press Release]
[NASA JPL] For the past few decades, scientists have been observing natural ocean fertilization events — episodes when plumes of volcanic ash, glacial flour, wildfire soot, and desert dust blow out onto the sea surface...
