The foliations of gneiss make beautiful swirls and patterns in polished countertops and building slabs. Many so-called granite countertops are actually gneiss. Gneiss makes a gneiss [sic] countertop! If by useful you mean info on gneiss, it is basically a coarse-grained, foliated, high grade metamorphic rock. Gneiss forms during high grade, regional metamorphism, and can form from amny different parent rocks including shale and igneous rocks. Most gniesses are often granitic in composition and one variety forms from the metaporphism of granite. Gneisses are also named for the dominant material such as biotite gneiss or garnet gniess.

What else can I help you with?
Put some heat and pressure on granite and you'll get?
Gneiss, if the heat and pressure are sufficient.
What is a sentence for gneiss?
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!
A foliated dense rock that has light and dark colored banding?
The rock you are likely describing is gneiss, which is a metamorphic rock with alternating light and dark bands. Gneiss forms when intense heat and pressure cause the original rock to recrystallize, resulting in distinct layering of minerals.
When the metamorphic rock schist is heated and squeezed it forms what?
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.
What geologic process change granite igneous rock into gneiss metamorphic rock?
Granite can be changed into gneiss through the process of metamorphism, where heat and pressure alter the mineral structure of the rock. This process causes the minerals in the granite to recrystallize, forming distinct banding and foliation characteristic of gneiss. The original minerals in the granite are reorganized into new minerals such as mica, quartz, and feldspar, giving gneiss its unique appearance.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
What are the Features of gneiss rock?
The main characteristic of gneiss is gneissic texture, foliations (banding) caused by the parallel alignment of constituent minerals as a result of heat and pressure.
What type of rock is an example of Gneiss?
Gneiss is an example of a metamorphic rock.
What group is gneiss in?
A Gneiss is a Metamorphic rock
How is gneiss similar to granite?
Granite is an igneous rock and gneiss is a metamorphic rock.
What is the origin of a gneiss rock?
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
What is gneiss mineral group?
Gneiss is a rock, not a mineral.
What is the color of a Gneiss rock?
A Gneiss rock is somewhat dark-greenish, depending on when it was made.
Put some heat and pressure on granite and you'll get?
Gneiss, if the heat and pressure are sufficient.
What is a sentence for gneiss?
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!
What rock is gneiss from?
Gneiss can be formed by the metamrphism of either granite or schist.
