University of Miami Radiocarbon Dates XVII

Abstract

The following radiocarbon dates are a partial list of samples measured for a variety of projects and materials since April 1979. Chemical and counting procedures remain the same as indicated in R, v 20, p 274-282. Calculations are based on the 5568 year Libby 1C half-life. Precision is reported as one-standard deviation based only on statistical counting uncertainties in the measurement of the background, NBS modern standard, and sample activities. 8130 values are measured relative to PDB and reported ages are corrected for isotopic fractionation by normalizing to -2S%. An additional 400 year reservoir age correction has been applied to marine carbonates.
