ZIP-related Subduction Session at the Goldschmidt Conference 2016

We would like to draw your attention to the theme “Subduction” at the 26th Goldschmidt Conference 2016, which will be held in Yokohama (Japan) from June 26th to July 1st.

One of the sessions will be organized by Thomas Pettke, Sarah Penniston-Dorland, Susanne Skora, Tatsuki Tsujimori and Matthias Konrad-Schmolke and feature work from the ZIP project.
We strongly encourage scientists and students to contribute to this session. Abstract deadline is February 26th.

“07b: Geochemical Recycling in Subduction Zones: What Goes in, What Comes Out, and What Happens in between:

This session aims at attracting geochemists and petrologists contributing to our better understanding of geochemical cycling and mass transfer of elements and isotopes in the subduction factory. Such processes are often at the onset of the global-scale dynamics that formed and have modified Earth’s geochemical reservoirs through time. Recent experimental, (micro)analytical and field-based research advances now allow us to gain unprecedented insights into how geochemical cycling has operated to form and continuously modify Earth’s geochemical reservoirs. We invite contributions that focus on what enters subduction zones, how this material evolves with progressive subduction and what is eventually recycled to the continental crust via arc magmatism or back to the convecting mantle. Studies dealing with element abundance and isotope ratio systematics, aqueous and carbonic fluid chemistries, halogens, fluid – solid phase petrology, thermal conditions, modelling, and field-based or experimental investigations are equally appreciated. We particularly encourage contributions that present provocative ideas and concepts, and unconventional approaches, to foster inspiring scientific exchange on the physical and chemical processes operating down to subarc depth.”

The 4th ZIP newsletter is dedicated to Evguenii Burov, who passed away on the way to the ZIP Consolidator field trip in Chile on the 9th of October 2015. An obituary on the first page shall honour his life and work. May you rest in peace, Evguenii!

The newsletter covers two major ZIP events in 2015:
1. The ZIP Starter I cruise on geophysical data acquisition in the Tyrrhenian and Ionian Sea in July 2015. Fellows accompanied the team of the CSIC (Barcelona) for approximately 10 days during their geophysical data acquisition campaign onboard the “B/O Sarmiento de Gamboa”.
2. The ZIP Consolidator field trip and associated short courses in Chile during October 2015 that addressed the monitoring and understanding of an active subduction zone.

ZIP Buz – Update I

Today, the underlying mechanisms that generate earthquakes at greater depth, i.e. deeper than 60 km, are still unknown. These earthquakes cannot be explained in the same way as shallow earthquakes, because pressure and temperature conditions are different. Due to better seismic imaging methods it is possible to localize even smaller and deeper earthquakes… read more
