Protactinium-231 Dating of Carbonates by Thermal Ionization Mass Spectrometry: Implications for Quaternary Climate Change
Edwards Rl, Cheng H, Murrell Mt, Goldstein Sj,
Abstract:
Measurement of protactinium-231 ($^{231}$Pa) in carbonates by thermal ionization mass spectroscopy yields $^{231}$Pa ages that are more than 10 times more precise than those determined by decay counting. Carbonates between 10 and 250,000 years old can now be dated with $^{231}$Pa methods. Barbados corals that have identical $^{231}$Pa and thorium-230 ($^{230}$Th) ages indicate that the timing of sea level change over parts of the last glacial cycle is consistent with the predictions of the Astronomical Theory. Two Devils Hole calcite subsamples record identical $^{231}$Pa and $^{230}$Th ages, suggesting that the chronology of this climate record is accurate
