Constraint ages of the formation of the craters based on the correlation with IODP expedition 382 site Site U1536. (A) Age constraints over seismic background based on biostratigraphic and paleomagnetic ages57. (B) Seismic record of a single crater from complex C (C) Seismic record of a single crater from complex B. (D) Seismic record of the sequence of craters from complex B. See Fig. 1B for location. Yellow dots are the inflection points of the reflectors interpreted as marking the events of collapses of the craters (1–4) shown in Fig. 4A. VCZ: Vertical Chaotic Zone. S1 and S2 are the paleosurfaces above the forced folds marking the timing of sill emplacements according Magee et al.55. Numbers are age in My ties with the U1536 Site25.
