Brief description Nickel iron sulphide mineralogy: the link between mineral transformations and microstructure and magnetic properties. This project is about measuring the rate at which minerals transform or react and how metal diffusion controls these reactions. Metal diffusion in sulphides is much more rapid that in silicates and is still very significant at low temperatures (< 300 C). In this project, we are trying to measure the rate at which the principal ore of nickel, pentlandite, transforms to violarite, another important nickel rich sulphide that forms from it in the upper parts of ore bodies. The arrangement of the metal atoms in these minerals is sensitive to temperature, so it may be used as a geothermometer.
