Abstract
THE wide occurrence of the three aluminium silicate minerals andalusite, kyanite and sillimanite either individually or in pairs, or sometimes all together in metamorphic rocks1,2, makes the study of these minerals attractive to petrologists and experimentalists because their presence and associations may be used to delineate the temperature and pressure range of a given metamorphism.
