New evidence for water trapped in minerals deep within the Earth's interior
The University of New Mexico
Researchers from the University of New Mexico and Northwestern University report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form – the ingredients for water are bound up in rock deep in the Earth’s mantle – the discovery may represent the planet’s largest water reservoir.

SOCIETY NEWS


2015 Award Nominations are now open
GS
While at Goldschmidt2014, did you see a presentation from a young geochemist making it clear that he or she is off to a great future? Did one of the presentations confirm to you that the presenter has been doing great geochemistry for a long time, but without adequate recognition? Many outstanding geochemists have not received the recognition that their excellent work deserves.

Help break this trend. Nominate them for a Geochemical Society Award. Awards not only provide recognition of quality work for the award winner, but they also help to advance the field of geochemistry by letting research institutions know that the work of one of their faculty is highly regarded by their peers. Nominations are simple and the nomination deadline is Oct. 15.

ELEMENTS: Kaolin
GS
The June issue of Elements was taken to press on June 9. This issue on kaolin illustrates admirably how materials known and used since the dawn of humanity may still have many surprises in store for us in terms of new uses and applications. Guest Editors Paul Schroeder and David Bish chose to present the whole spectrum of uses of kaolin, from ancient porcelains to nanocomposites. Kaolin-group minerals are among the most important industrial clay minerals, with a worldwide consumption in the millions of tons per year and applications in a wide range of industrial areas. Traditionally, their most important use has been in the paper and ceramic industries. New, innovative techniques have now allowed the synthesis of kaolinite–polymer nanocomposites, including bionanocomposites.

Current Geochemical Society members can access this issue now via the Elements online archive using your email address (UserID) and member number (Password).

How Earth avoided global warming, last time around
European Association of Geochemistry via ScienceDaily
Geochemists have calculated a huge rise in atmospheric carbon dioxide was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangea. A new model explains some of the events in the 80 million years following the start of the Carboniferous period.

Geologists confirm oxygen levels in Earth's oldest oceans
Syracuse University
Zunli Lu and Xiaoli Zhou, an assistant professor and Ph.D. student, respectively, in the Department of Earth Sciences, are part of an international team of researchers whose findings have been published by the journal Geology (Geological Society of America, 2014). Their research approach may have important implications for the study of marine ecology and global warming.

Echoes of ancient Earth identified by scientists?
European Association of Geochemistry via ScienceDaily
A previously unexplained isotopic ratio may represent the echoes of the ancient Earth, which existed prior to the proposed Theia collision 4.5 billion years ago. A research team has analyzed the ratios of noble gas isotopes from deep within Earth's mantle, and has compared these results to isotope ratios closer to the surface. The found that 3He to 22Ne ratio from the shallow mantle is significantly higher than the equivalent ratio in the deep mantle.

New evidence of how the Moon formed
AAAS
The origins of the moon have been as murky as a black hole's interior, with several hypotheses competing to explain this pockmarked body's beginnings. But, a new series of measurements published in the June 6 issue of Science makes one hypothesis the clear leader.

Subseafloor bacteria survive by over-activating DNA-repair and antibiotic target genes
European Association of Geochemistry via EurekAlert
The subseafloor is home to over one-third of the bacteria on the planet, but up until recently it was unclear if this huge microbial biosphere was alive and dividing. Now the same group that demonstrated this activity has shown that bacteria from the hostile sea-floor environment have adapted by over-activating stress response and DNA-repair mechanisms, to cope with the harsh conditions.
