[M-ZZ49] Frontiers of Geochemistry: Pioneering Research in a Changing World

Sun. May 24, 2026 1:45 PM - 3:15 PM 302 (International Conference Hall, Makuhari Messe)

Chairperson:Iizuka-Oku Riko(Department of Earth Sciences, School of Education, Waseda University), Tachibana Shogo(UTokyo Organization for Planetary and Space Science, University of Tokyo), Connolly Jr. Harold C.(Department of Geology, School of Earth and Environment, Rowan University)

In modern Earth and Planetary Sciences, innovative chemical analyses and perspectives serve as key drivers of scientific breakthroughs. This session aims to bring together researchers working at the forefront of geochemistry, including those pioneering advanced analytical techniques, those applying them across diverse fields, and those who use them to bridge disciplinary boundaries, to explore new directions in the geosciences.
The 2026 session, titled Frontiers of Geochemistry: Pioneering Research in a Changing World, will provide an international forum for scientists to address shared challenges and opportunities in a time of environmental and societal transformations. Discussions will highlight the current state and future perspectives of cosmo- and geochemistry, including circulation, partitioning, and transfer of elements in Earth and planetary systems, isotope fractionation and its effects on isotope ratios, and the identification of chemical species and processes.
As part of the JpGU-AGU joint meeting, this session encourages participants to look beyond disciplinary boundaries, consider element cycles in a broader context, and engage in dialogue on the chemical innovations essential to advancing geosciences. We seek to showcase innovative approaches, foster collaboration, and envision the future of geochemistry.
