This page points to available programs and other available tools for the calculation of timescales and other parameters from diffusion modelling.
ApTimer: a calculator of the timescale of F-Cl-OH diffusion in apatite, Weiran (Alex) Li, University of Cambridge, UK
This calculator is developed for estimating the timescale of multicomponent (F-Cl-OH) diffusion in apatite, and it can be applied to natural apatite that is zoned of F/Cl/OH. The calculated diffusion times can be related to magmatic processes such as magma ascent.
