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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
