Fig. 4: Synoptic temperature-time plot showing Phanerozoic thermal histories of glacial boulders and cobbles from interior East Antarctica.

Synoptic inverse thermal histories of groups 1 (blue) and 2 (green) (from Fig. 3) show episodes of rapid cooling highlighted with gray vertical bands. Periods of TAM uplift and exhumation are shown for reference with red arrows, with size of arrow indicating approximate relative amount of exhumation, for example, taken from previous studies26,32,35,36,37,38,39,40,41,42,43,44,45,46,47,48.
