Chemical composition of bulk sediments from ODP Hole 199-1221C

A record of inorganic geochemical variability was produced from a contiguous sequence of 35 samples, with 1 cm spacing, recovered from Hole 1221C. This record covers from 153.91 to 154.27 meters below seafloor and spans the Carbon Isotope Excursion (CIE) associated with the Paleocene/Eocene boundary interval. Elemental concentrations were determined for Al, As, Ba, Ca, Fe, K, Mg, Mn, P, Si, Sr, Ti, Cd, Co, Cr, Cu, Hf, Mo, Nb, Ni, Pb, Pt, Re, Sc, V, Y, Zn, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. Most concentration profiles exhibit a marked peak coincident with or just prior to the CIE. In addition, the rare earth element pattern exhibits a significant flattening of the typical, prominent negative Ce anomaly across the same interval.
