CORRECTION

Open AccessCorrection to: A full sequence of theMatuyama–Brunhes geomagnetic reversal
in the Chiba composite section, CentralJapan
Yuki Haneda1,2,3*, Makoto Okada2, Yusuke Suganuma1,4 and Takahiro Kitamura2

https://doi.org/10.1186/s40645-020-00354-y
Following publication of the original article by Haneda
et al. (2020a), several values of authigenic 10Be/9Be inFig. 7i and Additional file 2, and color of 6 plots around
12 m level in Fig. 7e were found to be incorrect. Thecorrected Fig. 7 and its caption is given below, and thecorrected Additional file 2 is included in this correction.
The original paper has been updated.

The original article can be found online at https://doi.org/10.1186/s40645020-00354-y.

limit indicated, for the principal component analysis. d VGP latitude calculated from the results of the hybrid demagnetization method. e–hNRM30-50/ARM30-50 and NRM30-50/IRM30-50 as relative paleointensity indices calculated following the pseudo-Thellier approach of Tauxe et al.
(1995), and linear correlation coefficients (R-valueARM and R-valueIRM) of the indices. i Authigenic 10Be/9Be (Simon et al. 2019) as an independent
proxy of the field intensity. j Natural remanent magnetization intensity. k Low-field (kLF) and ARM magnetic susceptibility (kARM) as proxies ofmagnetic grain concentration. l kARM/kLF as a proxy of magnetic grain size. m S-ratio at −0.3 T and −0.1 T as a proxy of the relative abundance of
antiferromagnetic to ferrimagnetic minerals. New data points obtained from the Yoro-Tabuchi section are shown as blue and light blue open
circles and lines, and new data points from the Yoro River section are shown as red and orange open circles and lines. Data points from previousstudies (Okada et al. 2017; Simon et al. 2019) are shown as black and gray closed circles and lines. The assignment of marine isotope stages isafter Haneda et al. (2020b). ARM, anhysteretic remanent magnetization; IRM, isothermal remanent magnetization; MBB, Matuyama–Brunhes
boundary; MS, magnetic susceptibility; NRM, natural remanent magnetization
