Formation of schist?

My sons\' questions for his homework project are: How are the layers of schist seperated into alternating light and dark minerals? Were the layers already there to begin with and then later became more altered with metamorphic processes?

The heat and compression deep within the earths magma are what cause these unique and interesting layers of striation.

Depending on the particular stresses and strains, heat and pressure applied, and the individual rocks and minerals there in that composed the material, they react differently and this is what causes the banding.
