Revised age model for U1423 based on projection of the “U1424_LR04 tuned age” (Tada et al. 2018) to site U1423 by the inter-site correlation of dark-light cycles for the last 1.5 Ma (red inverted triangles) and tuning of the GRA profile to the LR04 stack (vertical lines). Assuming that a high GRA represents glacial maxima, 118 horizons have been correlated to maxima of the oxygen isotope profile of LR04 for the last 2.975 Myr
