Is this a description for gneiss rock can be made from granite wavy bands of dark and light layers?
Yes, that description fits gneiss rock. Gneiss forms from the metamorphism of granite or other rocks, resulting in distinct wavy bands of dark and light mineral layers. This banding is a key characteristic of gneiss and helps distinguish it from granite.
Where is granite mined?
Granite is mined in various countries around the world, including Brazil, India, China, and the United States. In the United States, states such as Vermont, Georgia, and New Hampshire are known for their granite quarries.
Do basalt and granite make the layers of earth?
Basalt and granite are types of rock that can be found in Earth's crust, but they do not make up the layers of the Earth. The Earth's layers are primarily composed of the crust, mantle, outer core, and inner core, each with distinct characteristics and compositions.
What is the responsible for the formation of exfoliation domes?
Granite forms plutonsof igneous rock several kilometers below the surface as magmaslowly cools and crystallizes. The granite is under great overhead pressure.Then, granite is uplifted to the surface during a mountain-building event. During the mountain building process, the overlying rock iseroded as the granite is uplifted, and the pressure on the granite reduced. The granite expands and forms fractures or sheet joints parallel to the surface. The granite then erodes in concentric layers (similar to how an onion peels) forming rounded masses called exfoliationdomes.
The most common metamorphic rock made from granite?
The most common metamorphic rock made from granite is gneiss. Gneiss forms from the metamorphism of granite, which results in the segregation of different mineral layers that give gneiss its characteristic banding pattern.
What is found in the earth in layers and has to be mined?
Granite or precious stones
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.

Do any of earths layers have any iron or granite or basalt or iron and magnesium in it?
Yes

How do geologist determine mineral composition of granite?
They are able to slice the granite into extremely thin layers, observe it under a microscope, and view the amount and type of minerals that are present.

What is similar to granite that is about 30 km thick?
The Earth's continental crust is similar to granite and has an average thickness of about 30 km. It is composed of various rocks, including granite, and forms the outer layers of the Earth's landmasses.
How can a large block of granite form layers like an onion?
A large block of granite can form layers like an onion through a geological process known as fractional crystallization, where different minerals crystallize at varying temperatures as magma cools. As the granite is subjected to tectonic forces, erosion, and weathering, it can expose these distinct layers formed by the varying mineral compositions and textures. Additionally, repeated cycles of cooling and heating, along with hydrothermal activity, can further enhance the layering effect. Over time, these processes create the appearance of concentric layers similar to those of an onion.
What is metamorphosed granite?
Metamorphosed granite, also known as gneiss, forms when granite undergoes high temperatures and pressures deep within the Earth, causing its minerals to reorganize into distinct layers or bands. This process results in a metamorphic rock with a banded appearance and typically a coarser texture than the original granite.
