Short summary
Natural fission of Uranium U-238 in minerals produce tracks in the crystal lattice. The density of tracks crossing the mineral surface is traditionally used together with the uranium concentration and the decay constant to calculate the age of fast-cooling minerals. A new equation is developed which includes the track length distribution of the tracks. It is then possible to age date the tracks as a function of their length. A detailed tectonic history of the minerals can then be derived.
