摘要：Wonderkrater is a Late Quaternary archaeological site in the Limpopo Province of South Africa 1 , and has a high-resolution Late Quaternary pollen sequence 2-4 . An initial multivariate analysis of pollen spectra facilitated the quantification of a temperature index (SSF1) for two borehole sequences. 5 An attempt to calibrate the SSF1 temperature indices was made by Thackeray 6 . Scott et al. 7 and Thackeray and Scott 8 identified the ‘Younger Dryas’ cooling event in Borehole 3. This palaeoclimatic phenomenon is generally known in the northern hemisphere, dated between 10 600 and 12 900 BP (calibrated years). In this study, palaeotemperature estimates from the initial multivariate study 5 are re-examined in the context of calibrated radiocarbon dates 7 in order to make comparisons with dates for the Younger Dryas in the northern hemisphere.
