Complete the following statements about schist:
It contains large garnet .
The alignment of is 90 degrees to the pressure.

Complete these statements about gneiss:
( Gneissose banding, Schistosity ) forms.
Dark bands are made of ( silicic minerals, mafic minerals ) eg. ( muscovite, quartz, biotite ).

If their were impurities in the parent rock then ( spots of biotite, coloured streaks, garnet porphyroblasts ) will be visible in the marble.
