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!
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 is Gneiss composed of?
Gneiss is composed of mineral grains that are arranged into distinct layers or bands. The most common minerals found in gneiss include quartz, feldspar, and mica. The banding in gneiss is a result of intense heat and pressure during its formation, causing the minerals to segregate into layers.
What is gneiss streak?
Gneiss does not have a streak because it is a metamorphic rock composed of interlocking minerals with no cleavage. The streak test is typically used to determine the color of the powdered form of a mineral when rubbed against a streak plate, but this is not applicable to gneiss.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.
Does gneiss form from granite?
Gneiss may form from either granite or schist.
What origins do gneiss rock have?
Gneiss could eventually form from granite or from schist.

A metamorphic rock formed form granite?
Gneiss
What can granite heated under pressure form?
Granite heated under pressure can form a type of metamorphic rock called gneiss. This process causes the minerals in the granite to recrystallize and align in distinct patterns, giving gneiss its characteristic banded appearance.

Most common form of Mica occurring in Gneiss granite and schist?
muscovite
Does shale form from gneiss?
It can, indirectly. Shale is a sedimentary rock. Like many rocks, gneiss can be weathered down to very fine particles to the point that it becomes clay or silt. Those particles can then settle on the bottom of a body of water as mud. Under the pressure of burial, that mud can become shale. However, gneiss can also form from shale. Under long exposure to enormous heat and pressure shale will becomes slate, further heating and pressure will turn slate into phyllite, phyllite into schist, and schist into gneiss.
Which turn sandstone into gneiss?
The metamorphic process that turns sandstone into gneiss is called regional metamorphism. This process involves high temperature and pressure conditions deep within the Earth's crust, causing the minerals in the sandstone to recrystallize and align in layers to form gneiss. The distinctive banding and foliation of gneiss are a result of this intense metamorphic transformation.
