39. 231Pa age determinations. It is possible to have a concordant age even if the sample has behaved as an open system, if open-system behavior caused the isotopic composition to shift along concordia. An example of this type of behavior would be U loss for a material younger than 10,000 years. In this case, as the U is lost, the isotopic composition of the material will shift along a line with a slope very close that of concordia. In the case of the Barbados corals, all of the materials are significantly older than 10,000 years and would not be affected by this sort of artifact.

Recent data argue against this possibility [K. R. Ludwig, K. R. Simmons, I. J. Winograd, B. J. Szabo, A. C. Riggs, Science 259, 1626 (1993)]. Another concern (6) was that if the growth rate of Devils Hole calcite varied, linear interpolation of ages between dated subsamples would lead to inaccuracy. Recent data again argue against this artifact (K. R. Ludwig, personal communication).
