P–T modelling of the andalusite–kyanite–andalusite

Webevolution into the andalusite field can be explained by two different prograde paths. Granite intrusion caused the first prograde part of the path with andalusite growth. The subsequent thermal relaxa-tion, together with aH 2O decrease, generated the retrograde andalusite–kyanite transformation, plus chlorite consumption and chloritoid growth.
