5 Formation

5.1 Formation

Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
