What is the grain pattern of gneiss look like?
It looks like rows of beads.
What grain structure does gneiss have?
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
What is Grain size of metamorphic rock?
It varies some metamorphic rocks are fine grained (eg slate) and others have very large crystals (eg an augen gneiss).
What is the pattern of gneiss?
Banded
Is this a description for gneiss rock can be made from granite wavy bands of dark and light layers?
Yes, that description fits gneiss rock. Gneiss forms from the metamorphism of granite or other rocks, resulting in distinct wavy bands of dark and light mineral layers. This banding is a key characteristic of gneiss and helps distinguish it from granite.
Is Gneiss a sedimentary metamorphic or igneous rock?
Gneiss is a metamorphic rock that forms from the recrystallization of pre-existing rocks under high temperature and pressure conditions. It is characterized by its banded texture and coarser grain size compared to other types of metamorphic rocks.
What is the description of fine grain?
is a wood like substance
The most common metamorphic rock made from granite?
The most common metamorphic rock made from granite is gneiss. Gneiss forms from the metamorphism of granite, which results in the segregation of different mineral layers that give gneiss its characteristic banding pattern.
What is the grain of the timber?
The grain - is the pattern in the wood, showing the direction of the fibres.
What is the texture of gneiss?
Gneiss has a foliated texture, meaning it has visible layers or bands of different minerals. These layers are typically arranged in a repetitive pattern, giving gneiss a distinct texture that can vary in appearance depending on the type of minerals present.
What are 3 characteristics of a rock?
1.Grain Size 2.Grain Shape 3.Grain Pattern
Which layer of the earth can be described as thick made of granite and gneiss?
The layer of the Earth that fits this description is the continental crust. It is the outermost layer of the Earth and is primarily composed of granite and gneiss rocks. The continental crust is thicker and less dense compared to the oceanic crust.
