Z. to Wellington, N. Z.; March-April 1973)1031-1035Site 275 is located near the southeast margin of the Campbell Plateau about 600 km southeast of New Zealand and the same distance east-northeast of Campbell Island. The present depth of the sea floor is 2800 m. Five cores were recovered from the site with a total penetration of 62 m. Core 1 (4 samples), Core 2 (6 samples), Core 4 (1 sample), and Core 5 (1 sample) were examined for palynomorphs. The stratigraphic succession has been dated as Late Cretaceous and divided into two main lithological units, which are covered by a thin veneer of foraminiferal ooze and manganese nodules, of Pleistocene age. The upper unit (Unit 1) is comprised of a pale yellow and olive, soft, moderate to intense mottled sandy silt and glauconite-rich radiolarian diatom ooze. This includes all of Core 1 and all except the base of Core 2. Unit 2 is a dark olive-gray massive stiff, glauconite and nodule-bearing detrital clay silt. This unit includes the lowest section, Sample 2, CC, and all of cores 3, 4, and 5. A sharp contact separates units 1 and 2. Samples of ca 15-20 g were processed by using a standard HF/oxidation/flotation technique. Residues were mounted in safranin glycerine jelly.
