Metamorphic rocks that do not exhibit foliation.
Quartzite
Usually have a rougher texture
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.
False. The terms folidated and nonfoliated apply to metamorphic rocks.
A foliated rock will have mineral grains aligned in layers or bands, giving it a striped appearance. In contrast, a nonfoliated rock will have a more uniform texture without visible layers. One way to determine if a rock is foliated or nonfoliated is by examining its texture and observing whether it exhibits a banded structure.
Nonfoliated metamorphic rocks lack a layered or banded structure, unlike foliated rocks. Instead, they typically have a granular or crystalline texture. This texture results from the recrystallization of minerals without the development of preferred orientations, giving the rock a more uniform appearance. Examples of nonfoliated metamorphic rocks include marble and quartzite.
Non-foliated metamorphic rock, like quartzite and marble.
a banded texture
A banded texture
No, sedimentary rocks are classified based on their grain size, composition, and texture, not by whether they are foliated or nonfoliated. Foliation is a feature typically found in metamorphic rocks, not sedimentary rocks.
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.
Marble is a metamorphic rock that is nonfoliated, meaning it does not have a layered or banded appearance like foliated rocks such as schist or gneiss. Marble forms when limestone is subjected to heat and pressure, resulting in a recrystallized texture without distinct foliation.
