Integrated stratigraphy of the studied interval in the PLG core. (a) The stratigraphic framework with formations, polarity, stages, age (Ma), lithology, sediment colors, OAEs, planktonic foraminiferal zones1, and calcareous nannofossils zones of the PLG core3,6,7,19,26,29,30. OAEs are indicated by gray bands. Major planktonic foraminiferal turnover is highlighted in pale pink. Lithologies, color descriptions, and ages are given in the legend. (b) MS (black) with second-order polynomial trend (green-dashed line). (c) ARM (black) with second-order polynomial trend (green-dashed line). (d) δ13C profile from the PLG core (black) and Bottaccione section (dark blue). (e) 187Os/188Os ratios3,8,27,31.
