gneiss
No. The metamorphism of shale forms slate. Granite is formed when high-silica magma cools underground.
Hydrothermal metamorphism of a granite prototype.
A banded appearance. ---------- Gneiss itself, is a laminated metamorphic rock similar to granite.
Gneiss rocks are products of metamorphism while granite rocks are derived from igneous activity.
granite. it's very simmilar to Gneiss but lower grade of metamorphism
No. The metamorphism of shale forms slate. Granite is formed when high-silica magma cools underground.
Gneiss has a definite foliation of fabric, granite does not.
Hydrothermal metamorphism of a granite prototype.
Granite is Igneous rock. It crystallizes from hot melt (magma). Metamorphic rocks can be found associated with granite as result of their contact with country (surrounding) rocks. This will be a contact metamorphism. Metamorphism of granite it self results into granitic gneisses which are coarse foliated rocks.
A banded appearance. ---------- Gneiss itself, is a laminated metamorphic rock similar to granite.
Gneiss rocks are products of metamorphism while granite rocks are derived from igneous activity.
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)

No. Foliation is a texture most often used to describe the banded, platy, or layered appearance of certain metamorphic rocks.
Heat and pressure cause granite to change to gneiss.
Igneous rocks, such as granite, when subjected to extreme pressure and temperature will change to metamorphic rock. Evidence that an igneous rock had undergone metamorphism would include light and dark mineral banding; possibly with indications of partial melting in highly metamorphosed samples.
Intrusions of granite plutons change the surrounding rock through heat in a process known as contact metamorphism. Crustal collisions which may precipitate the melting of crustal material and its rise to the surface (and the creation of granite), also give rise to pressures and heat which can metamorphose other igneous, sedimentary, and metamorphic rocks in the surrounding area which is called regional metamorphism.
