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. WebAndalusite was reported by Burt and Stump ( I 984) from the pegmatites at Szabo Blufl Scott Glacier, Antarctica (lat 86'29'5., long 144"45'W.), that were discovered by Stump et …
