The presence of exogenous organic carbon is a major concern when radiocarbon dating bone. A particular source of error and frustration in the field of radiocarbon dating has been the analysis of bone that has undergone humification. Humification occurs during burial and results from a combination of two distinct processes: Maillard reactions involving indigenous organic carbon, and the complexation of collagen with soil humic substances. Soil humic substances—composed of fulvic acids, humic...
XAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERUXAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERU (2012)
Three samples of bone collected from Cuncaicha Rockshelter in Peru were pulverized at the University of Arizona and received for XAD purification and AMS radiocarbon dating. These samples represent three unique specimens identified as vicuña (Vicuna mensalis) or Andean deer (Hippocamelus antisensis).
