Figure F4. Generalized lithostratigraphy, biostratigraphy, and magnetostratigraphy of Leg 172 sites, except Site 1064. Note the similar sequence of units at all sites. As discussed in the text, this most likely reflects coherent variation of sediment distribution by deep ocean currents basinwide through the late Pliocene and Pleistocene (modified from fig. 2 in Shipboard Scientific Party, 1998b).
