EAG-GS Outreach Program: First AFIPS workshop – Call for abstracts

AFIPS_100As part of the EAG-GS Outreach Program to Africa, the European Association of Geochemistry (EAG) and the Geochemical Society (GS) are co-sponsoring the Africa Initiative for Planetary and Space Sciences (AFIPS).

The first AFIPS International Workshop, one of two workshops sponsored by the EAG-GS initiative, will take place in Addis Ababa, Ethiopia, on the 4th-7th February 2019, and will be hosted by the Ethiopian Space Science and Technology Institute (ESSTI) and Bahir Dar University.

More information can be found at http://etssti.org/invitation-for-workshop/.
The deadline for abstract submissions is 4 January 2019.

Videos of Jim McQuaid’s 2018 Distinguished Lecture Tour now online

JimMcquaid_100Videos of two lectures from Jim McQuaid’s 2018 EAG Distinguished Lecture Tour, filmed at Eötvös Loránd University (Budapest, Hungary), are now available on the EAG YouTube channel. Jim gave a series of lectures in universities across Poland, Hungary and Romania in November, before making his final stop of the tour in Croatia on 5 December.

GPL1831_abstract_100Bridging the depleted MORB mantle and the continental crust using titanium isotopes
Z. Deng, F. Moynier, P.A. Sossi, M. Chaussidon

The mechanisms driving the chemical complementarity between depleted MORB mantle (DMM) and continental crust (with an average ‘andesitic’ composition) remain unclear. By investigating Archean komatiites, and modern enriched (E) and normal (N) MORB samples, we demonstrate that partial melting of the mantle does not fractionate Ti isotopes, whereas […]

GPL1830_abstract100An oxygen isotope test for the origin of Archean mantle roots
M.E. Regier, A. Mišković, R.B. Ickert, D.G. Pearson, T. Stachel, R.A. Stern, M. Kopylova

The origin of the peridotites that form cratonic mantle roots is a central issue in understanding the history and survival of Earth’s oldest continents. A long-standing hypothesis holds that the unusual bulk compositions of some cratonic peridotites stem from their origin as subducted oceanic serpentinite, dehydrated during subduction to form rigid buoyant keels (Schulze, 1986; Canil and Lee, 2009). […]

GPL1829_abstract_100Microplastics contaminate the deepest part of the world’s ocean
X. Peng, M. Chen, S. Chen, S. Dasgupta, H. Xu, K. Ta, M. Du, J. Li, Z. Guo, S. Bai

Millions of metric tons of plastics are produced annually and transported from land to the oceans. Finding the fate of the plastic debris will help define the impacts of plastic pollution in the ocean. Here, we report the abundances of microplastic in the deepest part of the world’s ocean. […]

GPv7n2_cover_100CO2: Earth’s Climate Driver
Wally Broecker

In this new Geochemical Perspectives, Wally recounts the evolution of climate over Earth’s history in six brief episodes, from the early Earth and conditions on our planet under the faint young sun, through the current global warming challenge stemming from the burning of fossil fuels. Along the way Wally reviews some of the major evidence and enigmas of the geologic record and how these have revealed not only the climate of the past, but which processes were critical for this evolution. Through it all, Wally is careful to point out what we feel we now know, as well as research directions that might be most fruitful in the future. Written in a concise and easy to follow text, this should be an enlightening read for experts and novices alike.
