英文摘要: Abstract(#br)Accelerator mass spectrometric (AMS) radiocarbon measurements were performed with carbon samples extracted from cast iron and steel artifacts excavated in the 13th to 14th century Karakorum site of the Mongol period. The 14 C levels in most specimens were too low to represent the real age of the given artifacts, particularly in cast iron objects, whose 14 C concentrations were negligible. This discrepancy was much less pronounced in steel objects, but still quite significant. One notable exception was found, however, in a steel artifact whose radiocarbon date was consistent with its known age. These AMS data suggest that mineral coal was employed primarily for the smelting of cast iron while charcoal served as the major source of fuel for other iron and steelmaking processes....
