Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Etymology
From French schiste, Greek skhistos i.e. split
From the Greek word migma which means a mixture

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.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
