If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
Metamorphic rock that show layers of dark minerals alternatin with layers of light minerals are classified as?
Foliated is the correct answer!!!
Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as?
foliated metamorphic rocks. The alternating layers are caused by the alignment and segregation of minerals during the metamorphic process, resulting in a banded or layered appearance. Examples of foliated metamorphic rocks include gneiss, schist, and slate.
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.
What is the segregation of light and dark colored minerals into thin layers or bands?
The term is foliation.
Is this a description for gneiss rock can be made from granite wavy bands of dark and light layers?
Yes. This metamorphic rock can be made from granite; wavy bands of dark and light layers.
If a rock has bands of light and dark layers it is what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.

It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
If a rock has bands of light and dark layers it is?
It could be foliated metamorphic rock or sedimentary rock, depending on its mineral makeup and method of formation.
The metamorphic rock texture that has alternating bands of light and dark minerals is?
gneiss

What is the difference between conglomerate and gneiss?
Conglomerate is a clastic sedimentary rock that has rounded pebbles included among its clasts. Gneiss is a high-grade foliate metamorphic rock characterized by alternating light and dark bands. It forms from the metamorphism of granite or schist.

The term is foliation.
What are rocks called with alternating bands of light and dark silicate minerals?
They are probably gneiss, a banded metamorphic rock.
What term is used to describe metamorphic rocks with a banded texture?
The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.
