Elements June issue: Redox Engine of Earth
This issue of Elements reviews how redox chemistry is used to derive valuable information about the present and the past of our planet. A knowledge of redox states is essential to understanding the compositional makeup of our planet and the fundamental processes that occur from the core to the atmosphere, from magmatic systems to aquatic systems. And the social and economic impact of redox geochemistry is enormous because of the control it plays on metal mobility and availability, and because of its widespread use for environmental hazard assessment.
Information for EAG members: Delivery of Elements print issues
Production and mailing of the April 2020 issue of Elements was unfortunately delayed due to the Covid-19 situation. Print copies have now been mailed and EAG members should receive their copies shortly. Delivery of the June 2020 issue is expected towards the end of July/early August.
All EAG members have online access to current and past issues of Elements (html and pdf versions) as well as the new digital edition. To access the online content, log in to the Elements website with your EAG membership details (user id = email address, password = EAG membership number).

Stable W isotope evidence for redistribution of homogeneous 182W anomalies in SW Greenland
We present the first high precision stable tungsten isotope data for a comprehensive Eoarchean rock suite from the Isua region of SW Greenland with the aim to reconstruct the sources and processes that controlled the inventory of W in...

Tardi-magmatic precipitation of Martian Fe/Mg-rich clay minerals via igneous differentiation
Mars is seen as a basalt covered world that has been extensively altered through hydrothermal or near surface water-rock interactions. As a result, all the Fe/Mg-rich clay minerals detected from orbit so far have been interpreted as secondary...

Contributions of visible and invisible pores to reactive transport in dolomite
Recent technical advances have demonstrated the importance of pore-scale geochemical processes for governing Earth’s evolution. However, the contribution of pores at different scales to overall geochemical reactions...

Clumped isotope temperature calibration for calcite: Bridging theory and experimentation
Clumped isotopes (Δ47) analysis in carbonates is becoming widespread across the geochemical community as a geothermometer that also allows for the reconstruction of the precipitating fluid δ18O composition. While initial…

In situ determination of sulfur speciation and partitioning in aqueous fluid-silicate melt systems
Current knowledge of sulfur behaviour in magmas is based exclusively on ex situ analyses. Here we report the first in situ measurement of sulfur speciation and partitioning between coexisting aqueous fluids and silicate melts. These data...

Lanthanum anomalies as fingerprints of methanotrophy
Methane is an important greenhouse gas whose emissions into the oceans and atmosphere are regulated by relatively unconstrained anaerobic and aerobic microbial processes. The aerobic pathway for methane oxidation is thought to...

Ureilite meteorites provide a new model of early planetesimal formation and destruction
Ureilite meteorites are ultramafic rocks derived from parts of the depleted silicate mantle of their parent planetesimal. We used Monte Carlo modelling to explain the observed array of oxygen isotopes and major element chemistry...

Past endolithic life in metamorphic ocean crust
The known deep subsurface biosphere on Earth persists in diversified habitats, including deep within igneous rocks of the oceanic crust. Here, we extend the range of the deep subsurface biosphere to metamorphic ocean crust of...

Carbon and hydrogen isotope fractionation in lipid biosynthesis by Sporosarcina sp. DSK25
Pressure dependent fractionation (PDF) of carbon and hydrogen isotopes in lipid biosynthesis by gram-negative piezophilic bacteria has been reported thus far, however, such PDF for gram-positive piezophilic bacteria remains to...

Hafnium isotopes in zircons document the gradual onset of mobile-lid tectonics
The tectonic regime of the early Earth has proven enigmatic due to a scarcity of preserved continental crust, yet how early continents were generated is key to deciphering Earth’s evolution. Here we show that a compilation of data...

Diversity and Inclusion in Academia and Society
Making The Outdoors Great For Everyone [Podcast]
[Science Friday] To understand why the outdoors is an unwelcoming place for some people, we need to look back at our violent history. Joining Ira to talk about this is Dr. Carolyn Finney, author of the book “Black Faces, White Spaces.” She is also a scholar-in-residence at Middlebury College in Vermont. And later in the conversation, Ira is joined by two scientists, biology graduate student Corina Newsome from Statesboro, Georgia, and exploration geoscientist Tim Shin from Houston, Texas. They’ll talk about what it’s like to do fieldwork while Black, and what responsibility academic institutions should have in keeping their students safe.

Greenland drilling campaign aims for bedrock to trace ice sheet’s last disappearance
[Science] Global warming is accelerating the melting of Greenland’s ice sheet, which locks up enough water to raise sea levels by 7 meters. In 2021, U.S. researchers will go to the frozen expanse to pinpoint the last time it disappeared. The 5-year, $7 million campaign, awarded last month by...

Terrawatch: unearthing snow's 'Fukushima layer'

First asteroid found within Venus’s orbit could be a clue to missing ‘mantle’ asteroids
[Science] Earlier this year, astronomers discovered an oddball asteroid inside the orbit of Venus—the first member of a predicted flock near the Sun. No bigger than a small mountain, the asteroid has now gained another distinction: It appears to be rich in the mineral olivine, which makes...

Algae turn Italian Alps pink, prompting concerns over melting
[The Guardian] Scientists in Italy are investigating the mysterious appearance of pink glacial ice in the Alps, caused by algae that accelerate the effects of climate change. There is debate about where the algae come from, but Biagio Di Mauro of Italy’s National Research Council said the pink snow observed...

Removal of atmospheric CO2 by rock weathering holds promise for mitigating climate change
[Nature News and Views] Achieving targets for mitigating global warming will require the large-scale withdrawal of carbon dioxide from the atmosphere. Writing in Nature, Beerling et al.1 report that enhanced rock weathering in soils has substantial technical and economic potential as a global...

Underwater caves in Mexico preserve one of the world’s oldest ochre mines
[Science] Crouching as she wound her way through a pinched underground corridor, a young woman grasped a torch in one hand, soot blackening the craggy ceiling above her. Guided by stacks of stones deeper and deeper in the darkness of the cave, she finally spied her prize: a blood-red vein of...

Even If We Cut Greenhouse Gas Emissions Tomorrow, it Would Take Decades for the Earth to Start Cooling Again
[UniverseToday] If—or hopefully when—we cut our Greenhouse Gas (GHG) emissions, we won’t notice much difference in the climate. The Earth’s natural systems take time to absorb carbon from the atmosphere. We may have to wait decades for the temperatures to drop. Of course, that...
