Study and sampling areas of tectonically exhumed accretionary complexes in central Japan. (A) Map of central Japan. The position of the study areas are indicated by rectangular frames and shown in more detail in (B, C, E). (B) Geological map of the Muroto Peninsula, southern Shikoku Island (after Katto et al. 1991). (C) Map of the Tokyo Bay area showing the location of the Miura and Boso peninsulas (modified after Saito 1992 and Fujiwara et al. 1999). (D) Zoom in of the western Boso Peninsula headlands, showing the sample positions in the Nishizaki Formation (geological units according to Yamamoto et al. 2005). (E) Bathymetric map of the Nankai Trough area with indicated sample locations at IODP drill sites. Samples and IODP drill sites are related as follows: K005: Site C0001; K004, K014, K015: Site C0004; K013: Site C0006; K011, K016: Site C0007; K020: Site C0011; K022: Site 0012. The black line marks the Kumano transect taken for the IODP drilling campaign in the Nankai Trough (see Figure 2).
