Effective range of carbon dating

Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.

This coverage gap lies beyond what is considered the effective range for radiocarbon and prior to what is considered the effective range for potassium-argon.This problem period may be even larger because: (1) some dating authorities believe that the effective range for K-Ar doesn't begin until about 400,000 ya, and (2) many of the older fossils are found at sites that lack the volcanic rocks necessary for K-Ar dating and hence cannot be dated by this method at all.Although young-earth creationists challenge the legitimacy of all of the dates obtained by the long-term radiometric methods, even evolutionists are beginning to admit that this dating gap presents a problem for them.“If you’re trying to look at archaeological sites at the order of 30,000 or 40,000 years ago, the ages may shift by only a few hundred years but that may be significant in putting them before or after changes in climate,” he says.Take the extinction of Neanderthals, which occurred in western Europe less than 30,000 years ago.

Evolution places severe demands upon fossils used to support it.

One thought on “effective range of carbon dating”

  1. But it depends, because some can't wait and they think that it's time because they really love someone (at least they think that). My mom and I used to always fight about that & I told her I would never do it.
