Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
What minerals make up the light bands of rocks?
pusssy
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.
Metamorphism occurs at hotspots where magma rises up through Earth.?
Contact
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.
How can you determine if a rock is foliated or nonfoliated?
You can determine because there is texture differences. Also, foliated rocks have visible layers or elongated grains of minerals. Nonfoliated does not have distinct layers or bands.
Has Bon Jovi worked for acdc?
no. their both separate bands no. their both separate bands
Do foliated rocks have layers?
Non-foliated metamorphic rocks generally do not have distinct layering.
What is the composition of geniss?
by altering bands of minerals
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
Does nonfoliated rock have distinct layers of bands?
I dov't know
What is metamorphic rocks that have parellel bands of minerals?
It is foliated
What type of rock texture results when extreme pressure causes minerals in metamorphic rock to realign or when minerals separate out into dark and light bands?
I do believe that the answer is "foliated". However I am not positive, but I do know that... Banding is another word for foliation, which is the grouping of certain minerals with the rock forming parallel bands that are perpendicular to the pressure that causes its formation. Banding of different minerals give some metamorphic rocks a striped appearance, involving the segregation of light and dark minerals into layers. Good luck with your question and I hope that this information has helped.
Metamorphic rocks with no distinct layers or bands are said to be what?
Non-foliated.
What is the arrangement of minerals in a parallel or wavy or flat bands?
foliation
What is a metamorphic rock showing minerals formed into bands?
Gneiss.
What is an arrangement of minerals in flat wavy or parellel bands?
foliation
