Yale Natural Radiocarbon Measurements IX

Abstract

The present list represents a major portion of the samples measured since publication of the last date list in 1963. As in previous lists, dates are reported in terms of the 5568 yr half-life. Infinite dates are reported as beyond a limit equal to 2Q above background. Nearly all of the samples were measured in one of three quartz counters with backgrounds of 0.7 to 1.2 cpm per liter of effective counting volume at working pressures of about two atmospheres. The age errors quoted are based only on the standard deviations in counting rates of sample and standards.

Age Reporting of Very Old Samples

“…We hope our results will clarify some points of the probabilistic interpretation of "infinite" dates and support the use of 2o-limit proposed by Stuiver (1969), and advocated recently by Stuiver and Polach (1977).…”

The gigantic Seymareh (Saidmarreh) rock avalanche, Zagros Fold–Thrust Belt, Iran

“…The radiocarbon age obtained for the present study can be compared with those reported by Stuiver (1969), Watson & Wright (1969) and Griffiths et al (2001) obtained from samples in a core from Lake Mirabad, a small lake that fills a surface depression in the Asmari-rich debris of the rock avalanche near its distal limit (Fig. 7b).…”
