Short summary
We present an open-access Python package (GDTchron) designed to forward model apatite (U-Th)/He, apatite fission track, and zircon (U-Th)/He ages using temperatures output by geodynamic numerical models. The software can be used in a parallelized workflow to calculate large numbers of ages. We present two examples of potential applications of GDTchron: a simple model of exhumation and a complex model of continental rifting followed by mountain building.
