Figure F7. Magnetostratigraphy and polarity chron assignments for Hole 1053A. Generalized lithostratigraphy and biostratigraphy are from Shipboard Scientific Party (1998f). The polarity rating system (see "Characteristic Directions, Polarity Rating, and Paleolatitudes" in "Procedures and General Magnetic Properties") from left to right is R, RP, RPP (at left vertical dashed line), R??, INT, N??, NPP (at right vertical dashed line), NP, and N.
