Abstract
Thermochronological methods such as U-Th/He and Fission Track Thermochronology (FTT) are based on the radioactive decay of uranium and thorium isotopes and the radioactive chains initiated in these isotopes. The U-Th/He is based on the accumulation of He, resulting from the alpha decays of this chain, while the FTT is based on the accumulation of tracks (defect trails), caused by the inte…
