Figure F46. Composite digital images of the Cretaceous/Paleocene boundary at Walvis Ridge Holes 1262B, 1262C, 1267A, and 1267B. A strong change in magnetic susceptibility (MS) and color reflectance (L*) indicate the Fe oxide–bearing nonbioturbated foraminiferal nannofossil boundary layer. Planktonic foraminiferal zones were extrapolated from sample locations indicated by black squares. The records are all at the same scale.
