Canon of Kings Lists of kings Limmu. It is not affected by external factors such as temperaturepressurechemical environment, or presence of a magnetic or electric field. The basic equation of radiometric dating requires that neither the parent nuclide nor the daughter product can enter or leave the material after its formation. Uranium is not the only isotope that can be used to date rocks; we do see additional methods of radiometric dating based on the decay of different isotopes.
