Data report: Magnetic susceptibility measurements on dababiya core

摘要

I reportmagnetic susceptibility point measurements on the lower Maastrichtian-lowermost Eocene section retrieved in a core taken near the GSSP for the Paleocene/Eocene boundary in the Dababiya Quarry (Upper Nile Valley, Egypt). This record of magnetic susceptibility supplements the visual core descriptions, with lower values corresponding to more calcareous intervals. Preliminary investigation suggests that cyclicity apparent in themagnetic susceptibility record is consistent with a response to variations in Earth's orbital eccentricity. This interpretation is consistent with biostratigraphy and would imply sedimentation rates varying in the range 6-11 m/Myr, with lower sedimentation rates associated with intervals of low susceptibility/high carbonate.
