Yale University geology and geophysics radiocarbon dates I
A radiocarbon dating system has been established at the Department of Geology and Geophysics, Yale University. Liquid-scintillation counting of benzene described by Noakes et al (1965) and Polach and Stipp (1967) is used. The operation is small, geared to solving geochemical problems, through the use of radiocarbon as a dating tool and as a natural tracer in combination with other geochemical parameters. The facility will collaborate on significant archaeologic and geologic problems. However, it will not be a facility to which samples are submitted routinely. The procedure follows those used by the authors cited, with subsequent refinements incorporated. The first ages measured by this method were made on deep-sea cores rich in calcium carbonate. delta/sup 13/C was not measured in these samples but will be measured in samples that require it. The /sup 14/C half-life of 5568 years is used in conformity with the style of the journal. The errors, in years, are 1/sub sigma/ counting errors which include the combined counting uncertainties of sample, background, and standard.
