The site was continuously cored to yield the following sequence of deposits: 0-27 meters-Brown zeolitic clay with abundant ferromanganese micronodules and ferruginous aggregates; barren except for upper 3 meters. Age: If no hiatuses exist, Quaternary to early Miocene. 27-108 meters-Nannofossil chalk ooze; radiolarians are present throughout but foraminifers are poorly preserved and restricted to 36 to 108 meters. A disconformity may exist near 43 meters (Oligocene-Miocene boundary). Age: Early Miocene to early Oligocene. 108-109 meters-Dark brown calcareous clay rich in ferruginous aggregates. Severely disturbed and contaminated. Age: Early Oligocene. 109-114 meters-Extrusive basalt. The upper interval, assuming that no hiatuses are present, has a sedimentation rate of about 1.5 m/m.y. The underlying ooze has a rate of 5 m/m.y., which is low for a calcareous sediment, suggesting that it was laid down mainly between the lysocline and the calcite compensation depth. The basal sediment is from the Globigerina ampliapertura (foraminiferal), Helicopontosphaera reticulata (nannofossil) and Theocyrtis tuberosa (radiolarian) zones, giving an estimated age of 34 to 36 m.y.
