What else can I help you with?
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 metamorphic rocks that have parellel bands of minerals?
It is foliated
Do all foliated metamorphic rocks have bands of minerals?
i believe they do yes.
The metamorphic rock texture that has alternating bands of light and dark minerals is?
The metamorphic rock texture that has alternating bands of light and dark minerals is called foliation. This texture results from the alignment of minerals due to directional pressure during metamorphism. Schist is a common type of foliated metamorphic rock.
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 common structure is found in a metamorphic rock?
fold
Is gneiss foliated or no foliated?
Gneiss is a foliated metamorphic rock, meaning it has visible layers or bands of different minerals. These layers are formed due to the intense pressure and temperature conditions that gneiss undergoes during the metamorphic process.
What is metamorphic rock banding?

What kind of metamorphic has its minerals grains arrange in planes or band?
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
What are metamorphic rocks that have a banded appearance due to the alignment of minerals called?
Metamorphic rocks that have a banded appearance due to the alignment of minerals are called foliated metamorphic rocks. This banding occurs when pressure causes the minerals to align perpendicular to the direction of the stress, creating distinct layers or bands. Common examples include schist and gneiss. The foliation reflects the mineral composition and the conditions under which the rock was formed.
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.
What Wavy bands of light and dark minerals visible in gneiss probably formed from the?
The wavy bands of light and dark minerals visible in gneiss likely formed from the process of high-grade regional metamorphism, where pre-existing rocks (such as granite or sedimentary rocks) were subjected to intense heat and pressure. This metamorphic process causes the minerals to recrystallize and segregate based on their composition, resulting in the characteristic banding. The light bands are typically rich in quartz and feldspar, while the dark bands are often composed of biotite, amphibole, or other mafic minerals. The wavy appearance of the bands can also reflect the dynamic conditions of deformation during metamorphism.
