Figure F3. Comparison of Mg/Ca and delta18OG.sacculifer with orbital parameters (Laskar, 1990). A. Comparison of Mg/Ca with eccentricity for the time interval 4.8–3.5 Ma. Comparison of Mg/Ca and delta18OG.sacculifer with obliquity for the time interval 3.7–2.4 Ma. Mg/Ca and delta18OG.sacculifer are shown as detrended (variations >185 k.y. are filtered) and normalized curves.
