Figure F2. Examples of lava attributes as seen in drill core from Leg 183. A. Peperitic texture from Unit 9 (interval 183-1138A-82R-3, 46-63 cm). The lava could have been fragmented by explosive mixing of hot lava with wet sediments to produce this texture, but it is also possible that this is simply the product of a loose volcanic breccia being filled by later sediments percolating down from the surface. B. Entrained clasts from Unit 11 (interval 183-1139A-65R-5, 42-52 cm). The margins of this clast have been largely assimilated back into the core of the flow, but the gas that was entrained with the clast has left a distinctive patch of vesicles within the flow. Vesicles in the core of the flow appear to have been deformed around the entrained clast but vesicles within the clast are undeformed. (Continued on next two pages.)
