* Foliated (banded) - minerals oriented along visible planes * Example: Schist (fine grain) (from slate) * Example: Gneiss (coarse grain) (from a variety of rock, one of which is granite) * Non-foliated (no banding) usually rock of one mineral) * Example: Quartzite (from sandstone - quartz) * Example: Marble (from limestone - calcium carbonate

Nonfoliated refers to a type of metamorphic rock that does not have a banded or layered appearance. These rocks have a more uniform texture and lack the parallel alignment of mineral grains typically seen in foliated rocks. Examples of nonfoliated rocks include quartzite and marble.

Which metamorphic rock had a nonfoliated texture?
Quartzite
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.
Which is a characteristic of all nonfoliated metamorphic rocks?
Lack of banding
Nonfoliated metamorphic rock definition?
Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure).
Which type of nonfoliated metamorphic rock is granular and made of quartz?
Quartzite is a nonfoliated metamorphic rock that is granular and composed mainly of quartz. It forms from the metamorphism of quartz-rich sandstone.
Which metamorphic rock had a nonfoliated texture?
Quartzite
What are three examples of nonfoliated metamorphic rock?
Quartzite, Marble, and Soapstone are three examples of nonfoliated rock.
Is gabbro a foliated or nonfoliated rock?
Gabbro is a nonfoliated rock, meaning it does not have a layered structure like foliated rocks such as slate or schist. Gabbro is a coarse-grained, intrusive igneous rock composed mainly of pyroxene, plagioclase feldspar, and sometimes olivine.
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.
What are three examples of nonfoliated metamorphicrocks?
lol no
Is phyllite nonfoliated?
No. Phyllite is definitely foliated.
Is rocksalt nonfoliated?
Rock salt is not foliated.
Is mica schist foliated or nonfoliated?
foliated
Is conglomerate rock foliated or nonfoliated?
Conglomerate rock is nonfoliated, meaning it does not have a layered or banded structure typically found in foliated rocks like schist or slate. Conglomerate forms when rounded gravel and pebbles are cemented together, creating a clastic sedimentary rock.
Foliated and nonfoliated are terms used to describe the texture of?
Foliated and nonfoliated are terms used to describe the texture of metamorphic rocks. Foliated rocks have a banded or layered appearance due to the alignment of minerals, while nonfoliated rocks lack this layered structure and have a more uniform texture.
Metamorphic rocks that are nonfoliated?
Usually have a rougher texture
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
