Board of Directors Nominations Now Open

September 01, 2016

The GS is seeking nominations to fill upcoming vacancies on the Board of Directors. The board governs and sets the strategic direction for all aspects of the society. Qualified nominees will be vetted by the Nominations Committee and a slate of candidates will be presented to the membership in this fall's board election.

Board members are expected to attend the annual meeting, which is typically held the day before the Goldschmidt Conference begins. Other meetings may be held during the year by teleconference/web meeting. Each member is also asked to serve on a GS committee. Directors have a fiduciary duty to the society, which means they shall act in good faith and take action they reasonably believe to be in the best interest of the society. Directors elected this year will serve from January 2017 until December 2019. The GS Bylaws explain the role of directors in greater detail.

All members in good standing are eligible to be nominated to serve on the board. The Nominations Committee seeks to achieve a balanced representation of the membership with respect to scientific discipline, region, gender, and race.

Open Positions
International Secretary
Non-Officer Directors (2)

How to Nominate
Nominations may be submitted to nominations@geochemsoc.org by Oct. 7, 2016. You should provide contact information for the nominee and yourself in the message. Nominees will be contacted before the election to confirm that they are willing to serve.

Elements: Deep-Mined Geological Disposal of Radioactive Waste

August 05, 2016

The construction of geological disposal facilities for radioactive waste will become a major focus of geological, mineralogical, and geochemical effort in coming years. Geological disposal raises complex technical issues, but it is also at the center of social and political controversy. Different countries have very different waste inventories and quantities of waste; they may also have different geological settings available to host a repository. This issue presents five case studies which illustrate the concepts for repositories hosted in clay, granite/gneiss, salt, and tuff. Also reviewed are the varied approaches to selecting a site that is also acceptable to local communities.

Elements: Enigmatic Relationship Between Silicic Volcanic and Plutonic Rocks

April 07, 2016

The relationship between silicic volcanic and plutonic rocks has long puzzled geologists. Do granites and rhyolites share a common origin or are they derived from completely different processes? This issue explores the rich set of observations from petrology, geochronology, thermal modeling, geophysical techniques, and geochemistry used to study the silicic volcanic-plutonic relationship. Finding a consistent explanation for the silicic volcanic–plutonic relationship bears on important Earth science questions, including, "How is silicic continental crust formed?" and, "Can we predict supereruptions?"

Five years have passed in Fukushima, but numerous long-term issues still remain

March 09, 2016

Five years ago, the Great East Japan Earthquake hit the Tohoku district causing 19,335 deaths; 2,600 people are still missing. The Fukushima Daiichi Nuclear Disaster, at level seven on the International Nuclear Event Scale (INES), released ~520 PBq of radionuclides and forced residents to evacuate miles away from the contaminated area. During the past five years, a large number of articles have been published on the earthquake and the subsequent events, including the radioactive Cs contamination on the land in Fukushima prefecture and in the ocean (geochemical NEWSin August 25, 2015).

Radioactive Cs contamination in the surface environment has been a serious issue and will remain so for decades to come given the half-lives of 134Cs and 137Cs are 2.06 and 30.07 years, respectively. Radioactive Cs is rigidly bound in interlayers of clay minerals and is retained in the surface soils (e.g., Kaneko et al., 2015). However, aircraft monitoring revealed that the radiation dose decreased faster than expected based on the Cs half lives (Fig. 1b), indicating that soil particles associated with Cs were transported through surface waters into the ocean (e.g., Yamasaki et al., 2016). In addition to Cs bound to clay minerals, Cs-rich micro-particles (~ a few μm), mainly composed of Si oxide glass associated with wt% level Cs and other metals, were recently reported (Adachi et al., 2013). Despite their low numbers, these Cs-rich micro-particles may be a considerable dose contributor to the ecosystem. In addition, the formation processes of these Cs-rich micro-particles can provide novel information on the reaction that happened inside the reactor pressure vessel (RPV) and the primary containment vessel (PCV) when the fuels melted down in units 1 and 3 at the Fukushima Daiichi Nuclear Power Plant (FDNPP). The decommission of units 1~4 is ongoing and the most difficult process will be the removal of fuel debris, which is a solidified form of the melted fuel mixed with cladding, other metals, and possibly concrete. Even the occurrence and properties of the debris are totally unknown at the present, because it is difficult to sample the debris and investigate the occurrence inside the PCV due to the extremely high radiation dose. Since the Cs-rich micro-particles contain some fission products, they provide valuable insights into the chemical reactions that occurred inside the PCV during the explosions. The Fukushima disaster will challenge many geochemists as the long-term issues including debris, contaminated water stored in tanks, and Cs contamination in the soils, are resolved.
