Figure F14. Digital image of a coarse-grained foraminiferal ooze turbidite horizon (interval 208-1266A-6H-3, 25–44 cm) showing a scoured basal boundary with minor oxides along this surface. The upper boundary of the turbidite layer is highly mineralized with black micronodules of Mn oxides concentrated along the interface of the coarse turbidite and fine enclosing sediments. Oxides also concentrate along depositional laminae, as in alternating thin bands above the turbidite horizon.
