内容記述 Accurate radiocarbon (^<14>C) and carbon isotope measurements on fossil bones require that all exogenous carbon be removed. The remove the foreign organic carbon and obtain reliable ^<14>C ages from bones, XAD-2 chromatography method was examined. The fossil bones used in the experiment were bone fragments collected from the Awazu submarine archeological site. The bone samples were demineralized with 4℃ 0.8N HCl and the acid-insoluble residue was concentrated by centrifugation and lyophilized. The demineralized bone powder was hydrolysed with 6N HCl at 110℃. Solids were removed by centrifugation before the filtered hydrolysate was passed through the XAD-2 resin to remove fulvic and humic acids. δ^<13>C values and ^<14>C ages for three fractions of decalcified bone powder, XAD-treated hydrolysate, and fulvic and humic acids in demineralization-hydrolysis-XAD treatment procedure. XAD-purified hydrolysates have more positive δ^<13>C values and older ^<14>C ages than gelatin collagen extracted by conventional method. The δ^<13>C values in fulvic and humic phases are significantly more negative than collagen fractions. Conventional collagen extraction method is sufficient for ^<14>C dating on well-preserved bones but insufficient on poorly-preserved bones, because the method does not totally remove exogenous organic carbon. XAD-2 resin is recommended for accurate ^<14>C and carbon isotope measurements.
