Figure F10. Photomicrographs of sand-sized lithic grains (possible ice-rafted debris), Hole U1404A. Scale bars = 100 μm. A. Overview of lithic grain types on a picking tray (63–150 μm sieve size fraction) showing large amounts of (angular) quartz grains and other mineral phases (Sample 342-U1404A-23H-3, 117–119 cm). B. Selection of sand-sized lithic grains (Sample 342-U1404A-20H-CC). C. Selection of sand-sized lithic grains (Sample 342-U1404A-22H-CC). Note the quartz grain in the lower right corner shows a conchoidal fracture. D. Two larger lithic grains of quartz (left) and rock fragment (right) (Sample 342-U1404A-19H-CC). E. Larger rock fragment with an unknown pinkish red mineral phase (Sample 342-U1404A-21H-CC).
