TOrmuUld 44.Using the diagram below, determine which oT the aluminosilicate(Al2SiOs) polymorphs is(are) stable at 400°C and 6 kbars pressure. AlSiO Phase Diagram Kyanite Silimanite 2 Andalus ite 200 400 600 800 1000 T °C
It has to be Kyanite, as at such high pressure of 6kbar , kyanite would be stable only not other two polymorphs.
You can have different polymorphic transformation in case of uplif...
