Principle of radioisotopic dating

While isochron dates have been used by both old-Earth and young-Earth proponents to promote their respective viewpoints, attacks on isochron dating have also been made by young-Earth creationists, such as William Overn.These creationists challenge the assumptions made by the isochron dating method itself.The first of these assumptions, that all rocks and minerals that formed from the same homogenous mixture have the same age, is not disputed (Overn 2005).The second assumption of isochrons is that the initial ratios of the daughter isotope to the non-decay product isotope of the same element are uniform throughout the sample.Radioactive decay has become one of the most useful methods for determining the age of formation of rocks.However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid.This amount is often unknown and is one of the downfalls of conventional radiometric dating.

Instead of using the initial quantity of daughter isotope, the ratio of daughter isotope compared to another isotope of the same element (which is not the product of any decay process) is used as the comparison for isochron dating.

Then the computed age based on the accumulation of daughter products will be incorrect (Stasson 1998).
