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.
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.
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 are rocks with stripes called?
Rocks with stripes are known as banded rocks or striped rocks. These stripes are often caused by the layering of different minerals or the presence of alternating bands of different mineral compositions within the rock.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.

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.

Skeletal muscle cells are striated that is they have alternating dark and light bands called repectively?
A and I bands
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 smooth muscle have alternating dark and and light bands on them?
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.

What way are the wavy bands of light and dark minerals formed by?
The wavy bands of light and dark minerals, often seen in metamorphic rocks like gneiss, are formed through a process called foliation. During metamorphism, intense heat and pressure cause the minerals to realign and segregate based on their composition and density, leading to the formation of alternating layers or bands. This layering is typically a result of differential stress, which causes the minerals to stretch and become elongated. The contrasting colors of the bands usually reflect the presence of different mineral compositions, such as light-colored quartz and feldspar alongside darker biotite or amphibole.
What are rocks with stripes called?
Rocks with stripes are known as banded rocks or striped rocks. These stripes are often caused by the layering of different minerals or the presence of alternating bands of different mineral compositions within the rock.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.
What planet has alternating bands of white brown red and tan?
The planet Jupiter has alternating white, brown, red, and tan bands. There are also yellow and orange bands that appear with storms and winds in the atmosphere.
