What else can I help you with?
Which kind of metamorphic rocks are massiv and lack banding?
nonfoliated rocks
What is nonfoliated texture?
Metamorphic rocks that do not exhibit foliation.
What property distinguishes foliated metamorphic rocks such as gneiss and schist from nonfoliated metamorphic rocks?
a banded texture
How are foliated metamorphic rocks different from nonfoliated metamorphic rocks?
Foliated are made of interlocking crystals, non-foliated are not.
Which is a characteristic of all nonfoliated metamorphic rocks?
Lack of banding
What are some examples of nonfoliated metamorphic rocks?
Examples of non-foliated metamorphic rocks are quartzite and marble.
What characteristic helps identify nonfoliated metamorphic rocks?
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.
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.
A classification of metamorphic rocks would inculde whether they are?
foliated and nonfoliated
Which characteristic helps identify nonfoliated metamorphic rocks?
Nonfoliated metamorphic rocks do not have a layered or banded appearance like foliated rocks. Instead, they exhibit a uniform texture and lack the alignment of minerals seen in foliated rocks. Nonfoliated rocks are typically composed of minerals that have recrystallized without forming distinct layers.
What property distinguishes foliated metamorphic rock such as gneiss and schist from nonfoliated metamorphic rocks?
A banded texture
Where are foliated and nonfoliated metamorphic rocks formed?
At varying depths under the surface.
