Diffusion modelling to constrain the duration of metamorphism
Stenhouse, Iona Rosslyn
In this study the application of the garnet-ilmenite system to the diffusion modelling technique was investigated. Experiments were undertaken to accurately determine the rates of geochemical processes that are associated with the garnet-ilmenite system. The diffusion parameters of elements within ilmenite have been quantified and it was found that the diffusivity is relatively fast compared to garnet. Therefore in a garnet-ilmenite diffusion model ilmenite diffusivity can be treated as...[Show more]
