What else can I help you with?
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.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
What type of rock is an example of Gneiss?
Gneiss is an example of a metamorphic rock.
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.
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.
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!
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.
