Isotope Stratigraphy
Early Palaeogene planktic foraminiferal and carbon isotope stratigraphy, Hole 762C, Exmouth Plateau, northwest Australian margin
... In the previously published nannofossil biostratigraphy for Site 762 (Siesser & Bralower, 1992), nannofossil datums and bio- zones were calibrated to the timescale of Haq et al. (1987). We have recalibrated the ...
