Figure F63. Comparison of core image and magnetic susceptibility, Core 342-U1409B-16X. The core catcher of Core 16X (not shown) belongs to nannofossil Zone NP11. Based on correlation with Hole U1409A, the rest of the core belongs to nannofossil Zone NP12. This core shows typical lithology for early Eocene cores from Site U1409, with a series of dark clay-rich layers roughly corresponding to peaks in magnetic susceptibility, indicating possible hyperthermal events.
