Figure 1. Interval 167-1010C-5H-4, 69-92 cm. A, C. BSEI photomosaics of laminated Ethmodiscus ooze. Brighter layers are mixed-sediment laminae, and darker, more porous layers are Ethmodiscus-fragment laminae. An "x" marks the position of bright, low-porosity burrows, with sharp boundaries, running horizontally along Ethmodiscus laminae, pushing the laminations apart. B. Core photograph of laminated Ethmodiscus ooze with scale in centimeters running down left side. Straight black lines tie the magnified BSEI mosaics to the core photograph.
