The technique has potential applications for detailing the thermal history of a deposit. As the mineral cools, the crystal structure begins to form and diffusion of isotopes is less easy. Another possibility is spontaneous fission into two or more nuclides.
The possible confounding effects of 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. The procedures used to isolate and analyze the parent and daughter nuclides must be precise and accurate.
