Figure F3. Close-up photographs of representative lithologies from lithostratigraphic Units I and II at Site 1257. A. Contact between the pale olive clay of Unit I and the pale yellow nannofossil chalk in the upper part of Unit II (interval 207-1257A-1H-2, 0–20 cm). B. The sharp color change, but otherwise similar lithology, of the subtly burrowed mottled dominant lithology typical of Unit II (interval 207-1257A-2H-2, 85

The sharp color change, but otherwise similar lithology, of the subtly burrowed mottled dominant lithology typical of Unit II (interval 207-1257A-2H-2, 85–105 cm). C. Deformation typical of gravity flow deposits (intervals 207-1257B-1R-2, 15–35 cm, and 5R-2, 25–50 cm).
