Part III: Carbon Isotopes in Archaeology

Profile of Saurq al-Hadid sediments with Loci labeled in white boxes. Hearths are located on the red line. Loci 7-9 are the deepest sediments below the lowest dotted line marking a stratigraphic boundary. Loci 6 & 3 is the lowest dotted line itself, a horizon that is dense with faunal remains. Locus 2 is a layer of clean Sand and Locus 4 is the uppermost layer of sediments and is an episode of intense metalworking (and is not associated with a radiometric date).

8. Use the d13C/12C ratios to determine what types of plants dominated the archaeological record for each locus. Write a paragraph describing your interpretations. Use the results from your radiocarbon lab results to create a chronology of landscape change. If we understand the environment to be drying over time, are there any surprising results?Refer to the publication below to interpret what types of plants each value Tykot, RH. 2004.
