Five sites from Shatsky Rise produced high-quality magnetic stratigraphies from the late Miocene to Holocene. Cycles identified in reflectance data from Sites 1207–1211 allowed astronomic calibration of the polarity reversal sequence from ~8 Ma to present. The assumption that there is no phase lag between sedimentary cyclicity and the astronomical parameters allowed the cycles to be tuned to the astronomical solution for obliquity. Cross-spectral analysis on the tuned age model indicated high coherence between the astronomic solution and the reflectance data and confirms the reliability of the tuning. The age model has been compared with other published astrochronologies and is found to be in good agreement with Hilgen (1991a, 1991b) (and, therefore, Cande and Kent [1995]) in the 1- to 6-Ma interval. In the 6- to 8-Ma interval the age model differs significantly from that of Lourens et al. (in press) and Hilgen et al. (1995) from the Mediterranean. It is in better agreement with the ODP Leg 138 timescale of Shackleton et al. (1995) from the Pacific Ocean.
