When platy materials have a parallel alignment, the rock is considered foliated. Foliated rocks have a layered or banded appearance due to the parallel alignment of minerals like mica or chlorite. This alignment typically occurs through pressure and temperature changes during rock formation.

When platy materials have a parallel alignment a rock is a what?
When platy materials have a parallel alignment, the rock is classified as a schist. Schist is a medium-grade metamorphic rock characterized by its foliated texture, where the aligned minerals, such as micas, give it a shiny appearance. This alignment occurs due to directional pressure during metamorphism, resulting in a distinct layering of the minerals.
What is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
What is a foiliated metamorphic rock?
A foliated metamorphic rock is a rock that has a layered or banded appearance due to the alignment of minerals in parallel planes. This alignment is typically a result of the rock being subjected to high pressure and temperature conditions during its formation. Examples include gneiss and schist.

What is the parallel alignment of platy grains in a rock called?
The parallel alignment of platy grains in a rock is called foliation. Foliation is commonly seen in metamorphic rocks where minerals align in a preferred orientation due to pressure and temperature changes during deformation.
The parallel alignment of platy grains?
The parallel alignment of platy grains is known as foliation and is commonly found in metamorphic rocks. This texture is a result of directional pressure during the rock's formation, causing minerals to align perpendicular to the direction of stress. Foliation provides valuable information about the rock's history and deformation processes.
What type of rock is phylite?
Phyllite is a low-grade metamorphic rock that forms from the metamorphism of slate. It contains fine-grained minerals such as muscovite, chlorite, and quartz, giving it a distinct sheen from the alignment of its platy minerals.
Does phyllite has layers?
Yes, phyllite does exhibit layering or foliation, which is a prominent feature resulting from the alignment of platy minerals like mica within the rock. This layering gives phyllite its characteristic silky sheen and distinct texture.
A metamorphic rock that has visible layers or bands?
Schist is a metamorphic rock that has visible layers or bands due to the alignment of platy minerals like mica and chlorite during the metamorphic process. These layers or bands give schist its distinctive foliated texture and can vary in color and composition depending on the minerals present.
What is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
What is a foiliated metamorphic rock?
A foliated metamorphic rock is a rock that has a layered or banded appearance due to the alignment of minerals in parallel planes. This alignment is typically a result of the rock being subjected to high pressure and temperature conditions during its formation. Examples include gneiss and schist.
In a metamorphic rock the alignment of the crystals or minerals determines whether the rock is?
Foliated or nonfilated
What metamorphic rock has no obvious alignment of any type of mineral crystals?
Nonfoliated rock
What is schistosity in rock?
Schistosity refers to a particular rock texture found in certain metamorphic rocks, that is a reaction to increases in directionally applied stress and temperature. Schistosity is present where the texture of the rock exhibits a platy, layered appearance, with visible crystals of micas and other minerals, oriented in the same direction. The mineral crystals have become aligned perpendicularly to the direction of the applied stress.
