Summary

Deep Sea Drilling Project Site 603, located on the Hatteras Outer Ridge, recovered 1025.26 m of sediment, revealing the sedimentological history of the lower continental rise from the late Aptian to the Recent. The site was influenced by pelagic sedimentation during the late Berriasian to Valanginian, with terrigenous sediment appearing in the late Valanginian to Aptian. A large turbidite system developed during the Aptian, with black shale turbidites deposited intermittently from the Hauterivian to the Late Cretaceous. Sea level rose during the Albian, causing a decrease in terrigenous sedimentation, and the site dropped below the calcite compensation depth. Late Paleocene to early middle Eocene pelagic claystone is disconformably overlain by middle Miocene hemipelagic claystone, with turbiditic silts and clays accumulating at the site, forming the lower continental rise hills of the Hatteras Outer Ridge.
