The full question is: What may be involved with metamorphism EXCEPT
A recrystalization into denser minerals
B new minerals forming in the solid state
C increased temperature or pressure
D hydrothermal activity
E melting of existing rock
E melting of existing rock is not part of metamorphism
contact metamorphism, regional metamorphism, dynamic metamorphism
It is called contact metamorphism.
Contact metamorphism can occur in this scenario.
Water contained within minerals in the subducting plate is released during metamorphism.
Rock metamorphism.
Shale is a sedimentary rock. In increasing metamorphism, the sequence begins with shale and leads to phyllite, schist, then gneiss.
heat or pressure
The two processes resulting from sedimentary into metamorphic rock are known as contact metamorphism and regional metamorphism. Regional metamorphism most notably involves two tectonic plates colliding, while contact metamorphism occurs due to the intrusion of magma.
