1.1 Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

5 Formation
5.1 Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
