Figure F50. Composite digital images of the Eocene–Oligocene sequence at Leg 208 sites. Also shown are magnetic susceptibility (MS), color reflectance lightness (L*), and gamma ray attenuation (GRA) bulk density data. The lithologic change from clay or clay-bearing nannofossil ooze to nannofossil ooze is associated with decreasing MS and GRA bulk density and increasing L*. The dashed line approximates the E/O boundary, and arrows suggest the "Oi-1" (earliest Oligocene Glacial Maximum) event.
