Remote vs. local control on the Preboreal Asian hydroclimate and soil processes recorded by an annually-laminated stalagmite from Daoguan Cave, southern China
Pelvic and Major Long Bone Fractures
Radiocarbon Calibration and Comparison to 50 Kyr BP with Paired 14 C and 230 Th Dating of Corals from Vanuatu and Papua New Guinea
We calibrated portions of the radiocarbon time scale with combined 230 Th, 231 Pa, 14 C measurements of corals collected from Espiritu Santo, Vanuatu and the Huon Peninsula, Papua New Guinea. The new data map 14 C variations ranging from the current limit of the tree-ring calibration [11,900 calendar years before present (cal BP), Kromer and Spurk 1998, now updated to 12,400 cal B P, see Kromer et al., this issue], to the 14 C-dating limit of 50,…
Mass Spectrometric 14 C and U-Th Measurements in Coral
We discuss U-Th and 14 C measurements in coral. Samples with U-Th dates in excess of 50 ka BP were chosen for study. Some bulk samples from this group have measurable 14 C dates, which range from 30 ka to 43 ka bp. These can be explained by 0.5–2.5% contamination by modern carbon. This small amount of contamination can produce significant offsets in 14 C dates of coral samples older than ≃10 ka. It may be undetectable in X-ray powder diffraction …
