Figure F37. Lowermost Oligocene through upper middle Eocene magnetic susceptibility records, Sites U1331–U1334. Radiolarian datums in this section guide the correlation (red lines) of these records. All records plotted using approximately the same depth scale. Oligocene section is expanded as we move southward toward the early Oligocene paleoequator (Site U1334); Eocene section is expanded at the northern Sites (U1331 and U1332) that are closer to the middle Eocene paleoequator. However, the northern sites have the most condensed Eocene/Oligocene boundary interval. The two-step transition from the Eocene to the Oligocene is most pronounced at Sites U1333 and U1334. T = top, B = bottom.
