Description :
Photomicrograph of andalusite + muscovite zone sample with the assemblage Ms+Bt+And+St+Grt+Pl+Qtz. Staurolite inclusions in andalusite are optically continuous and resorbed suggesting that andalusite was partially produced from the breakdown of staurolite. Aligned ilmenite and quartz inclusions in andalusite (S1) are oblique to external schistosity (S2; not visible; 10SRB-H303A).
