What is composed of alternating 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.
The metamorphic rock texture that has alternating bands of light and dark minerals is?
gneiss
If a rock has bands of light and dark layers it is what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
During metamorphism of granite into gneiss what happens to the minerals?
With the extreme heat and pressure causing the metamorphism into gneiss, the constituent minerals recrystallize into bands, usually alternating from light colored to dark, perpendicular to the direction of the pressure which is being applied. The exact cause of the banding is not fully understood at this time.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.

Skeletal muscle cells are striated that is they have alternating dark and light bands called repectively?
A and I bands
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 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.
Why do minerals change composition as they undergo metamorphism?
The minerals in the rock have been realigned into parallel bands in response to pressures exerted on the rock from a particular direction. The banding forms perpendicularly to the direction of the force.
What makes cells look striated?
The alternating A and I bands on the miofibrils.
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.
