Biotite The Ti02-content of biotite (coexisting with ilmenite) from gamet-staurolite
to kyanitestaurolite zone shows a gradual increase suggesting its relation with
the grade of metamorphism as described by (Kwak, 1968: Fleming, 1973;

(1) and garnet + chlorite + muscovite = staurolite + biotite + quartz + H20 (2) the
latter delineates the gamet-staurolite isograd. This may also represent an upper
limit of the stability of the association of chlorite with other reactants presumably ...
