[S-EM13] Geomagnetism, paleomagnetism and rock magnetism

Mon. May 27, 2024 9:00 AM - 10:15 AM 301A (International Conference Hall, Makuhari Messe)

convener:Yoichi Usui(Kanazawa University), Noriko Kawamura(Japan Coast Guard Academy), Chairperson:Yu Kitahara(Marine Core Research Institute, Kochi University), Noriko Kawamura(Japan Coast Guard Academy)

We will discuss magnetism associated with minerals, the Earth, and beyond. This session will mainly cover the following topics: (1) the magnetic fields of the Earth and other planets, (2) paleomagnetic field variations, (3) numerical and laboratory studies of magnetic field generation, (4) magnetic properties of rocks, minerals, and other materials, (5) surface magnetic anomalies of the Earth and extraterrestrial bodies, and (6) tectonics and paleoclimate reconstructions based on magnetic measurements. We also welcome (7) related developments in measurement methods and data analysis. We encourage contributions that stimulate interdisciplinary collaborations toward establishing the SEDI-Japan community. Presentations and discussions will be in Japanese or English.
