Marble will not show noticeable foliation, although it undergoes some pressure during metamorphism. That is because marble composition is almost 100% calcite. Even calcite crystals realign themselves perpendicular to stress direction, the realignment is still unnoticeable. However, if there are platy minerals, such as mica, which is really uncommon, marble should show foliated texture.

What are some example names of foliated and un-foliated rocks?
Some examples of foliated rocks include slate, phyllite, schist, and gneiss. Amphibolite can be either foliated or nonfoliated. Examples of nonfoliated rocks include anthracite coal, hornfels, serpentinite, soapstone, quartzite, marble, and metaconglomerate.
What is the parent rock of the nonfoliated metamorphic rock?
The parent rock of nonfoliated metamorphic rocks can vary, but some common examples include limestone, quartzite, and marble. These rocks typically form under high temperature and pressure conditions without the development of a layered texture like foliated rocks.
Rocks are foliated or nonfoliated depending on their?
Mineral composition and how they formed. Foliated rocks have a layered or banded appearance due to alignment of mineral grains, such as in slate or gneiss, while nonfoliated rocks lack this layering, like in marble or quartzite. Foliation typically results from pressure and temperature conditions during rock formation.
Why can you see layers in foliated rocks but not in nonfoliated rocks?
Foliated rocks have minerals aligned in layers due to pressure causing them to reorganize, resulting in a banded appearance. Nonfoliated rocks lack this alignment, so they do not exhibit distinct layers. Factors like heat and pressure drive the formation of foliation in rocks like gneiss and schist, while nonfoliated rocks like marble and quartzite do not have this structural feature.
List examples of foliated and nonfoliated rocksexplain the difference between the two types of metamorphic rocks?
Foliated rocks: gneiss, schist, slate - These rocks have a layered or banded appearance due to the alignment of minerals caused by pressure during metamorphism. Nonfoliated rocks: marble, quartzite, hornfels - These rocks do not have a layered structure and exhibit more isotropic mineral alignment. The difference lies in the presence (foliated) or absence (nonfoliated) of layers or banding caused by differential pressure during metamorphism.
What are some examples of nonfoliated metamorphic rocks?
Examples of non-foliated metamorphic rocks are quartzite and marble.
Texture term for metamorphic rocks that lack layering?
Non-foliated metamorphic rock, like quartzite and marble.
Is marbles foliated or nonfoliated?
Marble is non-foliated.
What are three examples of nonfoliated metamorphic rock?
Quartzite, Marble, and Soapstone are three examples of nonfoliated rock.
Which metamorphic rock had a nonfoliated texture?
Quartzite

Metamorphic rocks such as marble and quartzite are said to be what because their mineral grains are not arranged in parallel layers or bands?
Metamorphic rocks such as marble and quartzite are said to be non-foliated because their mineral grains are not arranged in parallel layers or bands like in foliated rocks such as slate or schist. This lack of alignment gives non-foliated rocks a more uniform texture and appearance.
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
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.
What does nonfoliated mean?
* 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
What is the parent rock of the nonfoliated metamorphic rock?
The parent rock of nonfoliated metamorphic rocks can vary, but some common examples include limestone, quartzite, and marble. These rocks typically form under high temperature and pressure conditions without the development of a layered texture like foliated rocks.
