As the mineral cools, the crystal structure begins to form and diffusion of isotopes is less easy.

At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes.

For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.

It is not affected by external factors such as temperature, pressure, chemical environment, or presence of a magnetic or electric field.

A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide.
