No, gneiss is metamorphic.
No. Gneiss is a metamorphic rock.
Gneiss is an example of a metamorphic rock.
gneiss has many properties depending on the type of gneiss it is but some common properties are fine or coarse grains, metamorphic "bands" on the rock, and it's composition which is feldspar,quartz, mica, and hornblende.
A Gneiss is a Metamorphic rock
Granite is an igneous rock and gneiss is a metamorphic rock.
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
Gneiss is a rock, not a mineral.
A Gneiss rock is somewhat dark-greenish, depending on when it was made.
I am trying to find out what the other two types of rock besides gneiss form the Matterhorn. Gneiss is a metamorphic rock. That's a nice piece of gneiss!
Gneiss, a metamorphic rock composed of granular minerals, typically does not scratch glass. The hardness of gneiss generally ranges between 6 and 7 on the Mohs scale, while glass has a hardness of around 5.5. Therefore, while some minerals within gneiss may be hard enough to scratch glass, the rock itself usually does not have the consistent properties required to do so.
Gneiss can be formed by the metamrphism of either granite or schist.
