Figure F9. Photomicrographs showing typical lithologies of Unit IV and V. A. Thin section of a coarse glauconite-rich horizon (Sample 207-1260B-34R-1, 1–4 cm; field of view = 2.5 mm). B. One of the foraminifer calcite cemented sands as seen in Figure F8C (Sample 207-1260B-37R-5, 108–111 cm; field of view = 1.25 mm). C. Typical calcareous claystone with quartz of Unit V (Sample 207-1260B-42R-2, 10–12 cm; field of view = 2.5 mm; cross-polarized light).
