Types of radiometric dating methods
But new research by creationists has revealed a large number of problems with radiometric dating.
In some cases such as Carbon-14 dating, radioactive dating actually gives strong evidence for a young Earth.
If the date generated by isotope dating analysis agrees with the conventional interpretation of the geological column, paleontologists will accept it as valid.
A date that disagrees with that interpretation is dismissed as an anomaly.
For example, K-Ar dating assumes that there was no argon in the original rock.
But if there was argon in the rock when it originally formed, then the age calculated will be millions of years too high. The greater the amount of daughter isotope, the greater the apparent age.
The formula below is a proper model that admits the possibility that some daughter isotope was present when the rock formed: where D is the amount of daughter isotope present at start.
In fact, the above formula is far too simple, because it assumes that the amount of daughter isotope was zero at start.This is not an example of malfeasance, but rather the result of assuming that the theory of evolution has been proved reliable, and therefore these seeming anomalies are due to contamination or other causes of analytical error.These out of place fossils or rocks are not considered a reason to question the theory.These out of place fossils would seem to pose a problem for radiometric dating methods which are still calibrated based on the position of fossils (relative dates) in the geologic column.However, these fossils are not problematic if one simply disregards their existence.
