Gneiss goes through what kind of metamorphosis?
Gneiss undergoes regional metamorphism, which involves high temperatures and pressures over large areas of the Earth's crust. This can result in the reorganization of minerals within the rock, forming distinct layers or bands of different minerals.
Which feature would easily distinguish schist and gneiss from quartzite and marble?
The presence of visible minerals aligned in bands or layers would distinguish schist and gneiss from quartzite and marble. Schist and gneiss show foliation due to intense metamorphism, while quartzite and marble are more homogenous in texture.
What are rocks called with alternating bands of light and dark silicate minerals?
Rocks with alternating bands of light and dark silicate minerals are called gneiss. Gneiss is a metamorphic rock formed under high temperature and pressure conditions, which causes the minerals within it to align in bands or layers.
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.
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.
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.

Which rock has a granite look with bands?
Gneiss
What is a rock in which coarse-grained minerals separate into distinct bands?
A rock in which coarse-grained minerals separate into distinct bands is called a gneiss. Gneiss forms due to high temperature and pressure, causing the minerals to recrystallize and segregate into light and dark bands.
Which feature would easily distinguish schist and gneiss from quartzite and marble?
The presence of visible minerals aligned in bands or layers would distinguish schist and gneiss from quartzite and marble. Schist and gneiss show foliation due to intense metamorphism, while quartzite and marble are more homogenous in texture.
What is a metamorphic rock showing minerals formed into bands?
Gneiss.

If a rock has shiny surfaces or bands of light and dark layers then it is?
The bands of light and dark are classic signs of Gneiss (Gneissose banding), but Gneiss is not necessarily shiny. It may be sparkly, but not shiny. However, a Slate IS shiny, but does not have the pretty banding. Another consideration is Schist, which has similar characteristics to Gneiss. My advise is that if you are classifying a rock that you are looking at, consider the grade of metamorphism, as it certainly is metamorphic. Also consider the mineralogy: what are the light and dark bands? Quartz, Feldspar (light)? Mica (biotite) (dark)? There are many possibilities. The mineralogy will help determine the original sedimentary rock, which you can then use to determine the metamorphic sample you have.
