Research Abstract |
Comparison between Relative Paleomagnetic Intensity(RPI) of oceanic sediment cores and Absolute Paleomagnetic Intensity(API) of volcanic samples are conducted. The volcanic rocks used are welded tuffs which bear wide spread tephras observed in sediment cores, lava flows recording geomagnetic excursions, and lava flows at Brunhes-Matuyama boundary. The results give linear relationship of RPI and API, except for a welded tuff whose stratigraphic correlation is not well determined, and enable us the absolute value calibration of the RPI. It also indicates that the RPI is appropriate as the record of geomagnetic intensity variation.
