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. http://www.minsocam.org/MSA/AmMin/TOC/Articles_Free/1999/Bebout_p1495-1505_99.pdf iron man full movie online free

WebThe metamorphic grades (staurolite and sillimanite isograds) are roughly parallel to the contact between granite and schist, indicating a metamorphic aureole related to the granite. Andalusite occurs mainly in the staurolite zone. Andalusite can be found embedded in the mica schist as short prismatic, blocky crystals up to about four inches.
