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.
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.
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
What does it mean when rocks have bands?
When rocks have bands, it indicates that they are composed of different layers of minerals or sediments. These bands can form due to varying environmental conditions or depositional processes over time. The layers may differ in color, texture, or composition, providing insights into the rock's formation history.
What is it called when a metamorphic rock has folds or bands?
When a metamorphic rock has folds or bands, it is called foliation. Foliation occurs when pressure and heat cause minerals within the rock to align in layers, creating a banded appearance. These layers can be folded or crumpled due to tectonic forces.
What is the description of foliated?
A rock with minerals aligned into 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.

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.
Why do bands of minerals develop in most metamorphic rocks?
It's because of foliation. Foliation is defined as the arrangement of a set of minerals in parallel, sheet-like layers that lie perpendicular to the flattened plane of a rock.
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.

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.
What is an arrangement of minerals in flat wavy or parellel bands?
An arrangement of minerals in flat, wavy, or parallel bands is known as a banded structure or banding. This structure is commonly seen in rocks like gneiss and schist, where different minerals align in layers or bands due to geological processes like metamorphism. The distinct bands are often a result of alternating composition or texture variations within the rock.
What does it mean when rocks have bands?

These bands can form due to varying environmental conditions or depositional processes over time.

Why are mineral bands in metamorphic rocks light and dark colored?
Mineral bands are light and dark colored because they are different types of rock. In the rock cycle different types of rock can stack on top of each other, this can be subducted into the earth near the Mantle where there is enough pressure the rocks can start to melt and change. Because different types of rock metamorphose into different rocks you can have many layers in a type of rock. These can be light or dark colors depending on the rock.
