[S-GC54] [JJ] Frontiers in Geochemistry

Wed. May 24, 2017 1:45 PM - 3:15 PM 101 (International Conference Hall 1F)

convener:Hiroyuki Kagi(Geochemical Research Center, Graduate School of Science, University of Tokyo), Yusuke Yokoyama(Atmosphere and Ocean Research Institute, University of Tokyo), Shogo Tachibana(Department of Natural History Scieces, Hokkaido University), Chairperson:Hiroyuki Kagi(Geochemical Research Center, Graduate School of Science, University of Tokyo), Chairperson:Yusuke Yokoyama(Atmosphere and Ocean Research Institute, University of Tokyo)

In modern earth and planetary sciences, many new findings have been obtained by using state-of-the-art technique. These new findings include highly precise and accurate data, which is supported by recent developments of the new analytical methods.

To use these data correctly and effectively, we need to deepen our knowledge on the methodology. This session aims at providing an opportunity for various geoscientists to get together and have a strategic discussion on frontiers in geochemistry and cosmochemistry.

Especially, researchers, who would like to apply such innovative techniques, will have chances to discuss with those who work on devising new geochemical methods. We welcome a wide range of cutting-edge geochemical topics, including technical development, which have a potential for breakthrough of earth and planetary sciences. Any presentations related to the direction of geochemistry and cosmochemistry in future are also welcome.

We expect wide-ranged and future-oriented discussion to develop geochemistry and cosmochemistry.
