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 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 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.
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.
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.
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 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 minerals make up the light bands of rocks?
The light bands of rocks are typically composed of minerals like quartz and feldspar. These minerals have lighter color tones such as white, pink, or beige, which contribute to the overall light appearance of the rock.
If a rock has bands of light and dark layers it is what?
It is likely a sedimentary rock, where the light layers are composed of a different material or grain size compared to the dark layers. This banding could be due to variations in sediment deposition over time.
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.
When gneiss is formed... quartz... feldspar... mica... and other minerals of granite are rearranged into alternation WHAT?
When gneiss is formed, quartz, feldspar, mica, and other minerals of granite are rearranged into alternating light and dark bands or sheets. This distinctive layering is a result of the intense heat and pressure that gneiss is subjected to during the process of metamorphism.
