Fig. 3: Evolutionary spectra of global δ18Obenthic, δ13Cbenthic, smectite/(illite+chlorite) and Mn/Fe ratios over the period of ~13.7–10 Ma.
From: Moisture variability in northeast Tibet following the middle Miocene Climate transition
A Global δ18Obenthic timeseries across the Miocene64. B Global δ18Obenthic timeseries for the interval of ~13.7–10 Ma64. C Global δ13Cbenthic time series for the interval of ~13.7–10 Ma72. D Smectite/(illite+chlorite) ratio from the Guide Section spanning ~13.7–10 Ma (this study). E Mn/Fe ratios from the Guide Section spanning ~13.7–10 Ma (this study). The yellow inverted triangles are the paleomagnetic age tie-points. MCT Miocene Climate transition, MCO Miocene Climatic Optimum.
