Fig. 3From: Reductive chemical demagnetization: a new approach to magnetic cleaning and a case study of reef limestonesMagnetostratigraphy of the Ryukyu Group on Miyakojima Island, Okinawa, Japan (modified from Anai et al. 2017). The Virtual Geomagnetic Pole (VGP) latitude for each specimen is plotted along the stratigraphic column. The samples used in the present study were taken from these sites. The geochronological constraints were provided by the magnetostratigraphy and biostratigraphyBack to article page
