In this system, the radioactive parent rubidium-87 ( ..the critical assumptions stated above.
In uranium–lead dating, minerals virtually free of initial lead can be isolated and corrections made for the trivial amounts present.
The big surprise is that the attack has come from an evolutionary geologist and has been published in a secular scientific journal! First, let’ s find out how radioactive dating methods are supposed to work.
Some types (technically known as ‘isotopes’) of ‘parent’ elements such as uranium, thorium, potassium and rubidium are said to be radioactive because the nuclei of the atoms are unstable, resulting in readjustments between the ‘particles’ (primarily neutrons and protons) in the nuclei with time.
In this article I shall point out some other dating methods which work the same way as the Rb-Sr method.
