Gneiss usually consists of visible crystals of aligned mineral assemblages.
A type of metamorphic rock similar to granite is gneiss. Gneiss is a foliated metamorphic rock that has a similar composition to granite but displays a banded texture due to the alignment of mineral grains during metamorphism.
It varies some metamorphic rocks are fine grained (eg slate) and others have very large crystals (eg an augen gneiss).
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
Foliated metamorphic rocks exhibit a layering affect with parallel layers of mineral crystals one on top of the other. A good example of this is gneiss, which has alternating layers of light and dark minerals. Foliation takes place when pressure is applied to crystals and they recrystallize or align themselves at right angles to the direction of the applied directional stress.

The rock Gneiss (depending on what state it is in) usually feels or has *rough patches *is usually black, grey or white *has tiny little crystals -Mia
No, gneiss is metamorphic.
Both are metamophic Rock. Gneiss is formed from Granite. Schist from other types it depends on what you are planning on drilling. Also it depends on what type of Schist. Gneiss would probably be the better choice though.
When schist is further heated and squeezed, it can form gneiss, another type of metamorphic rock. Gneiss is characterized by its banded texture and high-grade metamorphism.
No. Gneiss is a metamorphic rock.
It belongs to the Metamorphic rock type.
This rock is likely a type of metamorphic rock called gneiss. Gneiss forms under high heat and pressure conditions deep within the Earth's crust. The alternating layers of dark and light colors are a result of the rock's minerals recrystallizing into bands.
Shale is a sedimentary rock, not a metamorphic rock.
