Figure F4. Close-up photographs of representative lithologies, Hole U1375A. A. Multicolor basalt conglomerate in Subunit IIA (interval 330-U1375A-2R-1A, 1–41 cm), topped by (1) ferromanganese encrustation. Interpebble and cobble spaces are composed of foraminiferal limestone, fine-grained volcaniclastic sediment, cement, and voids with (2) bioturbations and (3) geopetal structures. This subunit is interpreted as a hemipelagic interval in the sedimentary cover of Achernar Guyot. B. Multicolor basalt breccia in Subunit IIB (interval 330-U1375A-2R-1A, 79–119 cm) with (1) erosional surface. Basalt cobble with jigsaw-fit texture includes (2) calcite cement in upper border and (3) sediment infills in some cracks. This subunit is interpreted as a debris flow deposit of the sedimentary cover of Achernar Guyot.
