Figure F18. Pillow lava units. A. Graphic log showing the characteristic structures of pillowed lobes at Site 1203 using an example from Unit 8 (interval 197-1203A-31R-1, 20-78 cm). B. Photograph showing an example of the glassy pillow lobe margins in Unit 18 (interval 197-1203A-39R-4, 100-115 cm). Note the thin vesicle band just inside the glassy selvage and the characteristic cube-jointed pattern.
