Yale Natural Radiocarbon Measurements VI

Abstract

The following list includes most of the measurements made since publication of Yale V; some measurements, such as a series collected in Greenland by A. L. Washburn, are withheld pending additional information or field work that will make better interpretations possible. In addition to radiocarbon dates of geologic and/or archaeologic interest, we give in the third part of the paper, for the first time since 1954 (Deevey and others, 1954), recent assays of C 14 in lake waters and other lacustrine materials, now normalized for C 13 content. Some of these C 13 values have been published separately (Oana and Deevey, 1960), but most have not.
