Why do ancient samples of coal, diamonds and other carbon-containing materials consistently contain [6] The first such curve was published by: Arnold, JR and WF Libby. High-precision (super 14C measurement of Irish oaks to show the natural 14C variations from AD 1840 to 5210 BC.

Age determinations by radiocarbon content: Checks with samples of known age. Subsequent revisions have been made, e.g., Reimer, PJ et al.

Carbon-14 dating depends on the amount of atmospheric carbon-14 relative to carbon-12. Other processes may affect the local concentrations of carbon-14.These effects are corrected for by comparing samples from different locations. Addresses and refutes the common defensive statements used by proponents of the dating methods.Special emphasis is on demonstrating that discrepant results are not the exception, but the rule, and that arguments used to justify so-called good dates are, when closely examined, arbitrary and without foundation. But the reality of the day is that any method based on assumptions can never offer absolute results.
