The complicated birth of a volcano
They are difficult to reach, have hardly been studied scientifically, and their existence does not fit into current geological models: The Marie Byrd Seamounts off the coast of Antarctica present many riddles to volcanologists. In the international journal "Gondwana Research," scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel in cooperation with colleagues from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research just published possible explanations for the origin of these former volcanoes and thus contributed to the decryption of complex processes in the Earth's interior.

Goldschmidt2014: Call for Sessions
The Goldschmidt2014 Call for Sessions is now open until Nov 8. The organizing committee has identified 25 theme areas, and a range of sessions have been proposed for each theme. Please take a look at the list of themes and sessions and discuss with your colleagues whether there are any obvious gaps in the program. If so please suggest sessions that you think would help make the program more comprehensive. Existing sessions are designed to be of broad interest such that they should attract at least 20 abstract submissions, please ensure that your suggested sessions apply similar criteria. The additional sessions submitted will be reviewed by the science committee, and included in the list of sessions where appropriate. If you have any questions about suitability or overlap of your proposed session with existing sessions, please contact the appropriate theme leaders.
ELEMENTS: Nitrogen and Its (Biogeocosmo) Chemical Cycling
Elements volume 9, number 5 (October) is in press. Most people associate the word nitrogen with the air we breathe, the fertilizers we use for growing our flowers and vegetables, and perhaps algal blooms in our lakes and rivers. There would certainly have been more than enough material for an issue on the nitrogen cycle at the Earth's surface. However, Guest Editors Gray Bebout (Lehigh University), Marilyn Fogel (University of California, Merced), and Pierre Cartigny (IPGP, Paris) chose to focus on the large-scale cycle of nitrogen, ranging from the cosmos to the deep Earth and its surface. How did our atmosphere come to be made up of 78% nitrogen? Even though nitrogen is present only in trace amounts in minerals, this is where most nitrogen is stored. Current Geochemical Society members, you may access this issue now via the Elements online archive using your email address (UserID) and member number (Password).
GS at GSA-Denver
We have a number of activities planned at GSA-Denver. Dr. Rebecca Lange (University of Michigan) will present the 2013 F. Earl Ingerson Lecture. Her talk, "The origin of highly evolved, voluminous rhyolites by progressive, multiple episodes of partial melting: The resolution of some paradoxes" will be presented on Sunday, Oct. 27, 2013 at 9:20 a.m. in CCC Room 205. The Geochemical Society will again be sponsoring a ticketed reception with MSA and the GSA-MGPV Division on Tuesday, Oct. 29, from 5:45 p.m. to 7:30 p.m., as well as welcoming attendees to our exhibit booth (Booth 1107).
Director Election ends Friday
If you have not done so already, please submit your vote before the online election closes on Friday, Oct. 25 (23:59 GMT). For your convenience, a final reminder ballot will be sent on Wednesday.
On the 2014 Slate of Officers are Laurie Reisberg and Derek Vance for Vice-President; Anton Eisenhauer and Takashi Murakami for Secretary; Chris Hawkesworth and Gert-Jan Reichart for Director; and Tomoki Nakamura and Yong-Fei Zheng for Director. These four positions will join the 11 other directors of the 2014 Board of Directors.
54 award nominations received
The GS received 54 new nominations for Society awards by the Oct. 15 deadline. Our thanks go out to the nominators and support letter writers for helping increase the number and diversity of the nominees. Thanks also to the members of the Award Nomination Committee for their efforts to increase the nomination pool. Increased numbers of nominations are critical to ensure that the awards recognize the best in geochemistry and that the nominee pool comes closer to representing the diverse membership of the Geochemical Society.

3-D model reveals new information about iconic volcano
Uppsala University via Science Codex
The volcano on the Scottish peninsula Ardnamurchan is a popular place for the study of rocks and structures in the core of a volcano. Geology students read about it in text books and geologists have been certain that the Ardnamurchan volcano have three successive magma chambers. However, an international group of researchers, lead from Uppsala University, Sweden, has now showed that the volcano only has one single magma chamber.
Team of ocean scientists set sail on 48-day Equatorial Atlantic adventure
University of Bristol
A team of ocean scientists have set sail on a first-of-its-kind expedition across the Equatorial Atlantic to collect coral samples at depths of 4,000 meters to help understand the environmental controls on largely unexplored deep-sea ecosystems. The European Research Council-funded project comprises paleoceanographers, chemists, geologists and biologists, who will be collecting sediment cores, seawater and fossilized deep sea corals, making at least five major stops on seamounts and the mid-Atlantic Ridge.
Crystals point to 'recycled' super-volcanic magma chambers
A thorough examination of tiny crystals of zircon, a mineral found in rhyolites, an igneous rock, from the Snake River Plain has solidified evidence for a new way of looking at the life cycle of super-volcanic eruptions in the long track of the Yellowstone hotspot, say University of Oregon scientists.
Acidification: The ocean's changing climate
The Energy Collective
Scientists overwhelmingly agree that carbon dioxide (CO2) emissions in the atmosphere cause global temperatures to rise. This has detrimental impacts for the environment due to changes in climate patterns.
Granite Wars — Episode II: A new phase
At the end of the 19th century and after the victory of "Plutonism" in the great Granite War, geologists accepted the idea that igneous rocks originate from deep inside earth. However the great variability of volcanic and plutonic rocks, from dark basalt to light-colored granite, was difficult to explain, as Earth's interior was assumed to be relatively uniform (based on the idea that earth formed by condensation of primordial matter, it was imagined like a succession of concentric shells).
