Figure F26. Basal lithologies of Hole 1186A sediment succession above basalt lava flows (interval 192-1186A-30R-1, 37-47 cm; Subunit IIIB; early Aptian). A 1-cm-thick breccia layer with volcanic glass fragments (45-46 cm) is overlain by 5 cm of dark reddish brown ferruginous claystone (40-45 cm) that contains a 5-mm-thick band of bluish gray clay. Above the claystone is yellowish brown bioturbated nannofossil limestone.
