Also the argon-argon dating technique can be used for the potassium-argon sequence to ensure that no initial half-life of the parent isotope, which can be obtained from tables such as the one given in [1]: Although radiometric dating is accurate in principle, the precision is very dependent on the care with which the procedure is performed.

The possible confounding effects of initial contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.

In this case, the only daughter nuclides to be found through examination of a sample must have been created since the sample was formed.

Precision is enhanced if measurements are taken on different samples taken from the same rock body but at different locations.

Alternatively, if several different minerals can be dated from the same sample and are assumed to be formed by the same event and were in equilibrium with the reservoir when they formed, they should form an isochron.

Various methods exist differing in accuracy, cost and applicable time scale.

All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
