Figure F17. Core section images annotated with volcanological features for pillow basalts in Unit IV, Hole U1350A (Sections 324-U1350A-25R-1 through 25R-8). Yellow dashed lines = pillow margins or interpillow crusts. These core sections exhibit globular peperite textures where pillow basalt and unconsolidated pelagic sediment have mixed, interior pillow cracks, concentric vesicles in pillow margins, and sediment incorporated into pillow interiors.
