NQ core to 624.15 mbsf. 13.03 to 45.97 mbsf, 11.29 m (34%) partially following CRP-2. 45.07 to 624.15 mbsf, 548.67 m (95%) new hole. Deepest core-lithology: hard sandy siltstone. Deepest core-age: earliest Oligocene (ca. 33 Ma on diatoms, nannofossils and dinoflagellates)
Comment:
Depth is top of 1 cm thick sample; B=Barren: no diatom valves or fragments present. T = Trace/reworked: rare fragments present. R = Rare: 1 complete valve in 5-30 fields of view. F = Frequent: 1 complete valve in 1-5 fields of view. C = Common: 2-5 complete valves per field of view. A = Abundant: >5 complete valves per field of view
