👉 Where does sillimanite and kyanite come from?

  • Small and intermittent production of sillimanite and kyanite has been recorded from the Williamstown kaolin deposits, 40 km northeast of Adelaide. These represent areas within the orebody that have not been highly altered to kaolin, and are removed during the initial screening process.

👉 Why are kyanite and sillimanite so important?

  • Phase relations and reaction rates among the Al 2 SiO 5 polymorphs andalusite, kyanite and sillimanite are important for the geothermometry and geobarometry of metamorphic rocks. Consequently, these subjects were extensively investigated at high temperatures and pressures.
