[S-EM34] Geomagnetism, paleomagnetism and rock magnetism

Tue. May 24, 2016 3:30 PM - 5:00 PM Convention Hall A (2F)

Convener:*Masaki Matsushima(Department of Earth and Planetary Sciences, Graduate School of Science and Engineering, Tokyo Institute of Technology), Yusuke Suganuma(National institute of Polar Research), Chair:Hiroyuki Hoshi(Department of Earth Sciences, Aichi University of Education), Hirokuni Oda(Institute of Geology and Geoinformation, Geological Survey of Japan, AIST)

This session is open to recent advances in all areas being concerned with geomagnetism, paleomagnetism, rock magnetism, and their applications to geophysical and geological issues. We welcome presentations on geodynamo, present and past geomagnetic behaviors, fundamental rock magnetic properties, and paleoclimatic changes and tectonic processes revealed by magnetic methods.
