Extended Data Fig. 3: Tuning points applied to the radiometric age model for the Junín piston core.
Age offset between the age model derived by tuning Junín GI to EPICA Dome (Antarctica) δD temperature proxy18 and the radiometric and RPI-based age model15 (black line) using the nine tie points in Figs. 2 and 3 (numbers). Positive (negative) values denote that the tuned age is older (younger) than the radiometric and RPI-based age model, with the differences largely falling within ±2 sigma uncertainty of the radiometric and RPI-based age model15 (grey shading).
