Figure F11. Comparison of the ages of Miocene sequences from the Bethany Beach borehole with the ages of sequences identified in New Jersey. Cross-hatched = uncertain ages. Also shown is the benthic foraminifer oxygen isotopic record for Atlantic deep-sea sites (modified after Miller et al., 1997). Mi events are major isotopic increases that are inferred to correlate with ice-growth events on Antarctica; arrows are placed at inflection points. Timescale after Berggren et al. (1995). VPDB = Vienna Pedee
Belmenite.
