Short summary
This study examines how high temperatures can alter the geochemical record in zircon crystals used to date rock events. Using computer simulations, we model how movement of atoms, radioactive decay, and the formation of new elements interact in a zircon under changing heat conditions. Our simulation is compared with measurements from rocks in southern India to estimate temperature history of the region. The work aims to improve insights from rock dating and our understanding of Earth's past.
