UCLA Radiocarbon Dates XI

Abstract: The radiocarbon dates reported in this list are almost all based on collagen measurements from human archaeologic bone material. This collagen was isolated according to the methods developed by Berger, Horney and Libby (1964), Ho, Marcus and Berger (1969), Longin (1971) and Protsch (1973). All samples were counted as CO2 gas at close to 1 atm in a 7.5L proportional counter with three energy channels. The 14C dates reported are calculated with the Libby half-life of 5568 ± 30 years as required by convention. 13… Show more

“…On this basis, the marine reservoir correction for this region was 750 years. Stafford et al (1990); b Green et al (1998); c Berger and Protsch (1989); d Kaufman (1980); e Johnson et al (2000); f Breternitz et al (1971); g Kirner et al (1997); h Berger et al (1971). The spread in marine shell ages from around the Gulf (Robinson and Thompson 1981;unpublished data) and results from archived pre-1950 salmon scales (Brown et al 1988;T Brown, personal communication) suggest that a reasonable estimate for the geographic variability in this correction is the equivalent of ±60 years.…”
