AN OVERVIEW OF ANDALUSITE IN SOUHERN AFRICA: GEOLOGY B

Imerys South Africa Abstract Andalusite is part of the sillimanite-group minerals, as well as sillimanite and kyanite, which are all structural polymorphs of Al2SiO5. The importance of these minerals is due to fact that at 1 350°C they convert to mullite (Al6Si2O13), a highly refractory compound. South Africa has the largest known reserves of Andalusite in the world and the largest portion of ...
