They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.

Gneiss is formed from what rock?
Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.
What type of rock is gnesis?
Gneiss is a metamorphic rock formed from either igneous or sedimentary deposits.
Why is gneiss in earths surface?
Gneiss is a metamorphic rock that is formed when heat and pressure is applied to an igneous or sedimentary rock. The old rock does not melt completely but reorganizes it's minerals to form banks of foliation giving it the light/dark bands. Gneiss is formed when you have a parent rock that is rich in silica. Since most of the continental crust is silica rich, gneiss it a common rock. It is the highest grade of metamorphic rock in the metamorphic sequence. The sequence goes like this: slate - schist - phyllite - rock.
Can you describe the 4 rocks formed by metamorphic grade which are Slate Phyllite Schist and Gneiss?
Four rocks formed by metamorphic grade are slate, phyllite, schist and gneiss. Slate and pnyllite are low grade; schist is a medium grade; and gneiss is a high grade rock.
What rock does gneiss come from?
Gneiss may come from either granite or schist.
What rock is gneiss from?
Gneiss can be formed by the metamrphism of either granite or schist.
Gneiss is formed from what rock?
Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.
A metamorphic rock formed form granite?
Gneiss
What are the differences between para-gneiss and orthogneiss?
Gneiss which is formed frm the metamorphism of ignous rock is known as orthogneiss and gneiss which is formed from the metamorphism of sedimentary rocks is known as paragneiss.
What is a metamorphic rock showing minerals formed into bands?
Gneiss.
When shale is exposed to heat and pressure this metamorphic rock is formed?
gneiss
What metamorphic rocks are formed from mudstones?
Slate,schist,gneiss are the metamorphic rock formed from mudstone.
What type of rock is gnesis?
Gneiss is a metamorphic rock formed from either igneous or sedimentary deposits.
Can igneous rock like granite can be formed into a metamorphic rock like gneiss?
Heat And Pressure
What metamorphic rock is formed from greywacke?
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
Can an igneous rock like granite be formed into a metamorphic rock like gneiss?
Heat And Pressure
What group of rock does gneiss belong in?
Metamorphic, because it is formed with heat and pressure
