Paleomagnetic direction profiles for the studied sequence. a Declination anomaly of declinations from true north (0°) deduced from the ChRM directions from pThD results. The horizontal dashed line and light blue shading indicate the average declination and its 95% confidence limit for each stratigraphic interval, respectively. b Declinations of ChRMs from pAFD (red) and pThD (gray) and corrected declinations from pThD in which the average declinations are adjusted to true north (blue). c Inclinations of ChRM directions from pAFD (red) and pThD results (blue). d Virtual geomagnetic pole (VGP) latitudes from corrected ChRM directions from pThD results shown in (b) and (c). Black, white, and gray circles indicate normal, reversed, and intermediate polarities, respectively. e Maximum angular deviation (MAD) values of ChRMs from pThD results. The horizontal dashed line indicates MAD of 15°, which is the criterion for extracting of ChRMs in this study. f Polarities based on the VGP latitudes shown in (d). Black, white, and gray bars indicate normal, reversed, and intermediate polarities, respectively
