yes.those are very common in metarmorphic rocks especially Gneisses.Usually banding is between felsic and mafic minerals.

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.
What are the characteristics of Hornfels?
Hornfels is a type of rock that is metamorphic. They usually have bands and fine grain, and can come in different colors, such as light gray and dark gray.
Is gneiss smooth and shiny?
Gneiss is a foliated metamorphic rock, displaying bands of light and dark minerals.
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.

The metamorphic rock texture that has alternating bands of light and dark minerals is?
gneiss
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.
What are rocks called with alternating bands of light and dark silicate minerals?
They are probably gneiss, a banded metamorphic rock.
What is a tool that separates a star's light into color bands and dark lines?
a spectroscope
What is composed of alternating bands of light and dark silicate minerals?
Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.
What is composed of alterning bands of light and dark silicate minerals?
Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.

A bands are dark bands?
Yes, in striated muscle you can think of the "A" bands as the dArk bands and the "I" bands as the lIght bands.
What are the characteristics of Hornfels?
Hornfels is a type of rock that is metamorphic. They usually have bands and fine grain, and can come in different colors, such as light gray and dark gray.
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.
