Abstract:
Age/Depth datums from Zhou and Kyte 1992. Table 5 includes age datums. Age was adjusted to GTS 2012 by converting fixed iridium anomaly K/Pg Boundary age of 66.4 (Zhou and Kyte 1992) to 66.04 and shifting the timescale by 0.36 Ma. This compiled table includes data from Table 2 (Barium concentration), Table 3 (Silica concentration), and Table 5 (Age/Sedimentation Model). Data in T2 and T3 did not include ages. The Age (Ma) GTS2012 column includes analyseries-generated ages for these samples.
Dry bulk density (DBD) was linearly interpolated for all samples used in this study from the values given below.
