Rarer calc-pelites contain gamet and epidote, porphyroblasts and locally kyanite.
Concordant gametiferous amphibolite is common, and the whole sequence is cut
by common quartz veins and pegrnatite. The contact between cover and ...

I, Fig. B). Andalusite is replaced by prograde pseudomorphic muscovite and the
relict of the former survives in the shimmer white mica (Plate.l, Fig.C). Many
gamets from this and andalusite-kyanite isograd appear cloudy which may be

Kyanite-biotite isograd A comparison of the AFM topology of the zones D and C (
Figs. ll and 12) shows that the staurolite-chlorite join of the zone C is replaced by
kyanite-biotite suggesting that the discontinuous (Fe-Mg) reaction, namely, st + ...
