Paleomagnetic studies on single crystals separated from the middle Cretaceous Iritono granite

Granitic rocks could be good recorders of deep-time geomagnetic field behavior, but paleomagnetic measurements on whole-rock granitic samples are often disturbed by the presence of unstable multi-domain magnetite. Kato et al. (2018) demonstrated that single plagioclase crystals separated from granitic rocks can be reliable recorders of the geomagnetic paleointensity by a series of rock-magnetic measurements and Tsunakawa-Shaw paleointensity experiments on plagioclase crystals of the middle Cretaceous Iritono granite, for which… Read more
