[S-EM15] Geomagnetism, paleomagnetism and rock magnetism

Sun. May 22, 2022 10:45 AM - 12:15 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Tetsuro Sato(Earthquake Research Institute, The University of Tokyo), convener:Yutaka Yoshimura(Faculty of Social and Cultural Studies, Kyushu University), Chairperson:Yutaka Yoshimura(Faculty of Social and Cultural Studies, Kyushu University), Chisato Anai(Center for Advanced marine Core Research, Kochi Univercity)

We are going to discuss the issues on the magnetic fields of the Earth and planets, paleo magnetism, rock-magnetism, and their applications. This session includes following topics: (1) observation and analysis of the magnetic fields of the Earth and other planets, (2) paleomagnetic field variations obtained from natural and archaeological materials, (3) numerical simulations on the magnetic fields of the Earth and planets, (4) measurements and theories of magnetic properties of rocks, minerals, meteorites, and other materials, (5) climate changes and surface tectonics based on the paleomagnetic measurements of rocks and sediments, (6) observations of the magnetic anomalies and the crustal magnetization models of the Earth, planets, and satellites, and (7) developments of the measurement method and data analysis. We encourage papers stimulating an interdisciplinary collaboration relating to establishment of the SEDI-Japan community. We also encourage presentations of students and young researchers. The presentations and discussions will be made in Japanese or English in this session.
