A Mica Garnet schist is a metamorphic rock formed from a shale or a granitic mother rock when this is squashed and heated at death in the crust.
Shale
Garnet schist-- as well as mica schist--can be found anywhere where clay rock with some calcite content-- such as siltstone or a mudstone, for example-- can be compressed (via metamorphism) and consequently sqeezed into rock-like layers.
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
yes it is many people think it is an igneous rock because it is red

Schist has A LOT of mica in it
shale
Shale
As you increase the temperature and pressure of Shale it metamorphism occurs. It changes in this order: Shale > Slate > Phyllite > Schist > Gneiss > Migmatite
Shale.
Biotite, muscovite, chlorite, talc, garnet, and kyanite are common in schist.
schist
under heat and pressure
Slate, after that it can continue to schist.
