Stratigraphic correlations and chronostratigraphic model with interpretation of regional relationships of subsidence and uplift that contributed to segmentation of the Miura–Boso forearc basin. a Stratigraphic correlations of the Miura, western Boso, and eastern Boso peninsulas. Stratigraphic divisions, calcareous nannofossil biostratigraphy, and magnetostratigraphy are based on our data sets and those of previous researchers (Urabe et al. 1990; Eto 1993; Eto et al. 1998; Kameo et al. 2010; Tamura and Yamazaki 2010; Kameo and Sekine 2013; Utsunomiya et al. 2017; Haneda and Okada 2019). b Stratigraphic model against a chronological axis. c Our interpretation of the regional relationships of subsidence and uplift that contributed to segmentation of the Miura–Boso forearc basin. The Kurotaki unconformity can be understood in terms of the major erosional event at around 3.2 Ma and several subsequent erosional events and overall onlapping deposition
