Figure F2. Stratigraphy of the upper Cenozoic Unit I recovered from Hole 1149A. Silicoflagellate bioevents are indicated and correlated to the magnetostratigraphic data (magnetic inclinations from Plank, Ludden, Escutia, et al., 2000) and the geochronologic timescale (according to Berggren et al., 1995). Change in the asperoid/fibuloid ratio and the relative abundance of aberrant specimens is also shown. Red lines in the lithostratigraphy column correspond to discreet ash layers. Blue lines correlate particularly significant bioevents to the geochronologic timescale (see "Biostratigraphy" for details).
