Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.
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.

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 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.
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
Yes, smooth muscle has alternating dark and light bands known as the A and I bands, respectively.
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.
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.
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.
No. Gneiss has foliation in the form of alternating light and dark bands.
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 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.
