Results from Site M0079. (A) Age constraints from calcareous nannofossils and magnetostratigraphy (black text) and interpreted ages from correlation of basin environment with eustatic sea level curve (grey dotted lines and text, see Methods). (B–M) Brunhes-Matuyama chron boundary; E. Hux.: first occurrence (FO) of E. huxleyi; P.Lac: last occurrence (LO) of P. lacunosa; E.Hux/Gp. crossover: crossover in dominance between E. huxleyi and Gephyrocapsa. Arrows indicate potential uncertainty of true depth position of age marker (see text and Methods), and age is given in parentheses; (B) Oxygen isotope stages (OIS); (C) Lithostratigraphic units and subunits, coloured by basin environment interpretation (blue: marine; green: isolated/semi-isolated; grey: undetermined), subunit 1–11 is slumped interval (orange), yellow denotes Unit 2; (D) Abundance/counts of calcareous nannofossils (light blue), benthic foraminifer (dark blue, dotted) and non-marine diatoms (green, dashed); (E) Estimated sand percent; (F) Bioturbation intensity; (G) Decompacted sedimentation rate (see Methods); and H) Sediment lithology coloured according to facies association, longer bars representing coarser intervals (Table S3; ref.³¹).
