Figure F1. Single-channel seismic KNR179-1 Line 7 showing a section through J-Anomaly Ridge. Note the thinning of the transparent Eocene reflector package below ~6.25 s two-way traveltime (~4.8 km). Drilling during Expedition 342 found that the Eocene package is composed of lower Miocene and Oligocene sediments overlying Eocene sediments. In addition, part of the Paleocene–Campanian seismic unit also includes pre-Campanian rocks, very likely extending into the Albian. For location, see Figure F8.
