IRD abundances and MARs for each sample are listed in Table 1. IRD compositions of the 250-µm to 2-mm size fraction and the >2-mm size fraction, are listed in Table 2 and Table 3, respectively, for each sample. IRD MAR values calculated for the different grain compositions in the 250-µm to 2-mm size fraction are given in Table 4.

IRD abundance (wt%) is plotted vs. depth downcore in Figure 1, and vs. calculated age in Figure 2. Figure 3 is a plot of IRD MAR vs. calculated age. Note the hiatus between ~1.7 and 1.4 Ma on the graphs.
