Age versus thickness diagram for the Anno Formation. Data points are based on the polarity reversal events and marine isotope stages (MISs) listed in Tables 1 and 2, in addition to calcareous nannofossil bioevents (Kameo and Sekine 2013) and radiometric ages (Makinouchi et al. 1983; Tokuhashi et al. 2000; Ueki et al. 2018). The Geomagnetic Polarity Time Scale (GPTS) 2012 is based on Ogg (2012)
