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.
A metamorphic rock that has visible layers or bands?
Schist is a metamorphic rock that has visible layers or bands due to the alignment of platy minerals like mica and chlorite during the metamorphic process. These layers or bands give schist its distinctive foliated texture and can vary in color and composition depending on the minerals present.
Metamorphic rocks having a banded or striped appearance?
Metamorphic rocks with a banded or striped appearance are called foliated rocks. These bands or stripes are formed due to the alignment of mineral grains or the presence of alternating layers of different minerals. Examples of foliated metamorphic rocks include gneiss, schist, and slate.
What is composed of alternating bands of light and dark silicate minerals?
A gneiss rock is composed of alternating bands of light and dark silicate minerals, typically formed through high temperature and pressure metamorphism of existing rocks like granite or shale. The light bands are usually composed of quartz and feldspar, while the dark bands are made up of minerals like biotite, amphibole, or pyroxene.
What type of rock texture results when extreme pressure causes minerals in metamorphic rock to realign or when minerals separate out into dark and light bands?
I do believe that the answer is "foliated". However I am not positive, but I do know that... Banding is another word for foliation, which is the grouping of certain minerals with the rock forming parallel bands that are perpendicular to the pressure that causes its formation. Banding of different minerals give some metamorphic rocks a striped appearance, involving the segregation of light and dark minerals into layers. Good luck with your question and I hope that this information has helped.

Is composed of alternating bands of light and dark silicated minerals?
Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.
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.

A metamorphic rock with visible layers or bands is said to be what?
A metamorphic rock with visible layers or bands is said to be foliated. The layers are due to the alignment of minerals or the presence of alternating light and dark bands. Examples of foliated metamorphic rocks include slate, schist, and gneiss.

Is it true or false that the texture of a sedimentary rock that does not have minerals arranged in bands is described as nonfoliated?
False. The terms folidated and nonfoliated apply to metamorphic rocks.
What is the texture called in metamorphic rocks with bands or layers?
foliated
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.
