Fig. 10. 1bree step refmement of age models for CEARIS cores. (a) Graphic correlation to &"0 age model of core
GeoB 1523-1 (48 tie points ). (b) Initial (dashed) and subsequent stage (solid) of synchronizing all bandpass filtered
susceptibility signals to the astronomical precession index (lag 1.77 kyr, 33 tie points). (c) Graphic correlation of
sub· Milankovitch band «15 kyr) features to their common mean age (90 tie points). (d) CEARIS stack.
