Tables
(Table 1) Geochronology (age) of Oxygen Isotope Stage boundaries is from Martinson et al. (1987) [back to stage 7], and Imbrie et al. (1984). Specific events are radiocarbon dated at 10, 11, 12, 13, 14 and 17,000 years BP (details in text). The Pennard and Minchin Hole D/L Stages are from Bowen et al. (1985). For chronostratigraphic correlations see Bowen and Sykes (1988), Behre (1989) and Bowen et al. (1989). Sites outside Wales are correlated with Oxygen Isotope Stages as follows — Upton Warren, St Germain II and Odderade (Sub-stage 5a), Chelford, BrOrup and St Germain I (Sub-stage 5c) and Stanton Harcourt and Aveley (Stage 7).
