Crystalline schists. A characteristic series of minerals, for the 

 most part silicates, is found in micaceous, hornblendic and argil- 

 laceous schists. They occur embedded and disseminated through 

 the mass of the rock and reach their highest development along 

 the contact portion of the rock mass.

andalusite 



iolite 



amphibole 



sillimanite

Serpentines and talc. The minerals occurring in serpentine are 

 in some cases the unaltered species from which the serpentine was 

 derived, in other cases secondary minerals resulting from a fur- 

 ther alteration of the serpentine. They occur embedded and in 

 veins of various thickness traversing the serpentine masses.
