[S-EM17] 地磁気・古地磁気・岩石磁気

2026年5月28日(木) 15:30 〜 17:00 展示場特設会場 (7) (幕張メッセ国際展示場 7・8ホール)

座長:浅利晴紀(気象庁地磁気観測所)、安ヒョンソン(韓国地質資源研究院)、望月伸竜(熊本大学大学院先端科学研究部　基礎科学部門　地球環境科学分野)

The remarkable progress in Earth Sciences today owes much to our understanding of Earth's magnetic field. This session invites contributions on the latest advances in geomagnetism, paleomagnetism, rock magnetism, and their wide-ranging applications to geophysical and geological problems. We welcome presentations on topics such as the geodynamo, present and ancient geomagnetic field behavior, fundamental rock magnetic properties, paleogeography including tectonic processes, and insights into paleoclimate. In addition, we encourage submissions related to satellite- and ground-based magnetic field observations, studies of lunar and planetary magnetism, and magnetic investigations of meteorites, which are new windows into planetary evolution and solar system history. We also welcome innovative methodologies, software tools, and instrumentation that support and expand these research frontiers. Through this session, we aim to foster forward-looking discussions that will inspire future breakthroughs in magnetism-related Earth and planetary sciences. We encourage contributions that stimulate interdisciplinary collaborations toward establishing the SEDI-Japan community.
