What else can I help you with?
Which of the following is NOT an example of metamorphic rock marble gneiss slate shale?
Shale is a sedimentary rock, not a metamorphic rock.
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 is the primary mineral of Gniess?
Gneiss is a metamorphic rock which exhibits foliation (a layered effect). The layers of gneiss are alternating light and dark layers. Usually the lighter layers are rich in quartz and feldspar and the darker layers are rich in biotite mica, hornblende, or tourmaline.
Where is biotite most commonly found?
Biotite is most commonly found in igneous and metamorphic rocks. It can be found in granite, schist, and gneiss, among other rock types. Biotite is also often present in some sedimentary rocks, such as some sandstones.
How does gneiss differ from the rock it was formed?
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.
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 a metamorphic rock made from schist?
Gneiss is a metamorphic rock formed when intense heat and/or pressure is applied to it's parent rock schist.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
Which has a greater percentage of biotite in it?
To determine which rock type has a greater percentage of biotite, you would typically compare different igneous or metamorphic rocks known for their biotite content. For example, granite often contains less biotite compared to schist or certain types of gneiss, which can have a higher percentage of biotite due to their metamorphic processes. If you have specific rock types in mind, I can provide a more tailored comparison.
Is gneiss a metamorphic sedimentary or igneous?
Gneiss is a banded metamorphic rock.
Is gneiss an example of igneous rock?
No. Gneiss is a metamorphic rock.
What group is gneiss in?
A Gneiss is a Metamorphic rock
Is gneiss an igneous metamorphic or sedimentary rock?
It is a Metamorphic rock
Is gneiss igneous metamorphic or sedimentary rock?
It is a Metamorphic rock
What type of rock is an example of Gneiss?
Gneiss is an example of a metamorphic rock.
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
How is gneiss similar to granite?
Granite is an igneous rock and gneiss is a metamorphic rock.
