What are the differences between para-gneiss and orthogneiss?
Para-gneiss is a metamorphic rock derived from pre-existing sedimentary or igneous rocks, while orthogneiss is a metamorphic rock derived from the metamorphism of igneous rocks only. Orthogneiss typically has a more uniform texture and mineral composition compared to para-gneiss. Additionally, orthogneiss usually contains higher amounts of feldspar and other mineral grains that are indicative of its igneous origin.
What type of crystals does gneiss rock have?
Gneiss usually consists of visible crystals of aligned mineral assemblages.
What is the daughter rock of granite?
The daughter rock of granite is gneiss. Gneiss forms from the metamorphism of granite, where the minerals in the granite recrystallize and align into distinct bands or layers, giving gneiss its characteristic appearance.
Can you mine gneiss?
Yes, gneiss can be mined for various purposes such as construction materials or as decorative stone. Gneiss is a metamorphic rock that is often prized for its attractive banding and durability, making it desirable for uses in landscaping, architecture, and countertops. Mining gneiss involves extracting the rock from quarries or mines using similar methods to other types of rock mining.
What rock has a foliated dense rock that has light and dark colored banding?
The rock you are referring to is likely gneiss. Gneiss is a metamorphic rock that forms from the alteration of pre-existing rock under high heat and pressure. It often exhibits alternating light and dark bands due to the segregation of different minerals during metamorphism.
What is the probable rock origin of gneiss?

What is gneiss mineral group?

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!
What rock is gneiss from?
Gneiss can be formed by the metamrphism of either granite or schist.
Is gneiss a metamorphic sedimentary or igneous?
Gneiss is a banded metamorphic rock.
What origins do gneiss rock have?
Gneiss could eventually form from granite or from schist.
