Figure F27. Stratigraphic distribution of sand-sized lithic grains in the 63–150 µm size fraction (Sites U1402–U1411) and photomicrographs of sand-sized lithic grains (Sites U1404, U1406 and U1408). The focus of this study, and thus the lithic grains documented here, is the Cenozoic before the onset of the well-documented late Pliocene–early Pleistocene major northern hemisphere glaciation. Photos show high abundances of (angular) quartz grains, rock fragments, and other mineral phases. Foraminiferal tests, fish debris, and other biogenic material have also been observed. Question marks indicate unreliable biostratigraphic age assignments because of the largely sub–carbonate compensation depth positioning of Site U1403.
