Figure F21. Site 1263 high-resolution composite digital images of P/E boundary sections in Holes 1263A, 1263C, and 1263D (345.5–346.0 mcd) depicting abrupt chromaticity (a* [red diamonds]) and magnetic susceptibility (black circles) changes. Carbonate content (blue triangles) is illustrated for Hole 1263C. The Site 1263A clay/carbonate contact is unconformable. Roughly 25 cm of the basal clay is missing.
