To date older fossils, other methods are used, such as potassium-argon or argon-argon dating.

Other forms of dating based on reactive minerals like rubidium or potassium can date older finds including fossils, but have the limitation that it is easy for ions to move into rocks post-formation so that care must be taken to consider geology and other factors.

They tie themselves in logical knots trying to reconcile the results of radiometric dating with the unwavering belief that the Earth was created ex nihilo about 6,000 to 10,000 years ago.

Creationists often blame contamination Indeed, special creationists have for many years held that where science and their religion conflict, it is a matter of science having to catch up with scripture, not the other way around.

This is consistent with the assumption that each decay event is independent and its chance does not vary over time.

Other elements used for dating, such as rubidium, occur in some minerals but not others, restricting usefulness.

Through analysis, a bone fragment is determined to contain 13% of its original carbon-14.

The half-life of carbon-14 is approximately 5,730 years. Since the quantity represents 13% (or 13/100ths) of , it follows that This is based on the decay of rubidium isotopes to strontium isotopes, and can be used to date rocks or to relate organisms to the rocks on which they formed.

Radiometric dating — through processes similar to those outlined in the example problem above — frequently reveals that rocks, fossils, etc.

are very much older than the approximately 6,000 to 10,000 years reckoned by young earth creationists.

Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.
