Foliated and nonfoliated are terms used to describe the texture of?
METAMORPHIC!
Why is this important when trying to classify nonfoliated metamorphic rocks?
A non-foliated texture is cataclastic: the result of mechanical fracturing of rocks by the application of directional strain. The texture is chararcterised by the presence of brecciated and bent minerals and rock fragments.
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.
What is a metamorphic rock that has parallel alignment of mineral grains?
A folliated texture metamorphic rock, like shist.
What is metamorphic rocks with a non-foliated texture show metamorphic change that involves?

Which metamorphic rock had a nonfoliated texture?
Quartzite
Metamorphic rocks that are nonfoliated?
Usually have a rougher texture
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
Foliated and nonfoliated are terms used to describe the texture of?
METAMORPHIC!
What property distinguishes foliated metamorphic rock such as gneiss and schist from nonfoliated metamorphic rocks?
A banded texture
What property distinguishes foliated metamorphic rocks such as gneiss and schist from nonfoliated metamorphic rocks?
a banded texture
Texture term for metamorphic rock which lack banding?
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.
Texture term for metamorphic rocks that lack layering?
Non-foliated metamorphic rock, like quartzite and marble.
Is it true or false that the texture of a sedimentary rock that does not have minerals arranged in bands is described as nonfoliated?
False. The terms folidated and nonfoliated apply to metamorphic rocks.
Is sedimentary rock foliated or nonfoliated?
Sedimentary rock can appear foliated, but the nomenclature of foliation is usually reserved for the context of metamorphic rock texture description.
Contrast foliated and nonfoliated metamorphic rocks?
Foaliated rock can form in one or two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foaliation also occurs as minerals that have different compositions separate to produce a series of alternation dark and light bands. Most nonfoliated metamorphic rocks share at least one or two main characteristics. First, the original rock that is metamorphosed may contain grains of only one mineral or contains very small amounts of other minerals.
Why is this important when trying to classify nonfoliated metamorphic rocks?
A non-foliated texture is cataclastic: the result of mechanical fracturing of rocks by the application of directional strain. The texture is chararcterised by the presence of brecciated and bent minerals and rock fragments.
