Figure F3. Holocene-Eocene timescale and biostratigraphic datums used for Leg 183 Kerguelen Plateau Site 1139 (modified from Berggren et al., 1995; Erba et al., 1995). High-latitude zonations used during Leg 183 vs. low-latitude zonations are indicated under "Leg 183" and "Low Latitude" respectively, for foraminifers and nannofossils. High-latitude biostratigraphic datum and age correlations are indicated in bold type under "Biostratigraphic Datums;" foraminiferal datums are underlined. Planktonic foraminifer zonations adopted from Berggren (1992: Neogene Kerguelen); Stott and Kennett (1990: Antarctic Paleogene; modified by Huber, 1991 and Berggren, 1992); Cita et al. (1997) (nannofossil zonations adopted from Wise, 1983; Antarctic Oligocene to mid-middle Eocene, modified by Wei and Wise, 1990, and Wei and Thierstein, 1991, and calibrated against magnetostratigraphy by Wei, 1992). Note that some of the high-latitude datums are only correlated to magnetic chrons in the literature. Dashed zonal boundaries indicate uncertain datum levels. T = top/last occurrence, B = base/first occurrence. Bold entries = see "Zonations," , for explanation.
