Figure F4. Close-up photographs of different lithologies observed at Site 1204. A. Rotated, broken body overlying a thick interval consisting of a thin-faulted very finely laminated bed (at 30-45 cm) and convoluted laminations (below 45 cm), likely indicating slumping. Note the 2-cm brown beds of silt volcanic material alternating with finely laminated, bioturbated (e.g., at 35-40 and 45-48 cm) and burrowed (i.e., at 37 and 42 cm) nannofossil chalk (interval 197-1204A-3R-2, 29-49 cm). B. Sharply laminated bed of fresh basaltic vitric ash with sharpness decreasing upward and vertically bioturbated at top (interval 197-1204A-3R-5, 10-29 cm). C. The boundary between Unit III and Subunit IVA (Section 197-1204A-6R-1, 45-64 cm). D. Dendritic Mn/Fe concretions in olive palagonite clay (interval 197-1204A-6R-1, 79-98 cm).
