Alkali Feldspar Granite and Migmatite

1 Definition
1.1 Definition
Alkali feldspar granite, also known as red granite, is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

5 Formation
5.1 Formation
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
