Gneiss can turn into magma if, while underground, it is heated until it melts.
heat and volcanos
Magma would turn into igneous rock.
magma turns into lava.
shale → slate → phyllite → schist → gneiss
Gneiss turns into granite. Though it comes from shale."GNEISS can turn to migmatite and then totally recrystallize into granite."
It can.
No. its the opposite. gneiss forms after shale goes through metamorphism
heat and volcanos
by adding heat and pressure
No, but slate and gneiss are both a type of metamorphic rock. Slate will also turn into Gneiss, eventually, if metamorphosing continues. The series is Shale (sedimentary) >> Slate (metamorphic) >> Phyllite >> Schist >> Gneiss
It is impossible for granite to turn into gneiss it is a scientific impossibility that cannot be done with only heat and pressure :)
Magma would turn into igneous rock.
Granite will become gneiss.
magma turns into lava.
Granite will become gneiss.
shale → slate → phyllite → schist → gneiss
It turns into Gneiss if it is compressed in the right conditions and under the right temperatures.
