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 C14 in lake waters and other lacustrine materials, now normalized for C13 content. Some of these C13 values have been published separately (Oana and Deevey, 1960), but most have not.
