Foliation is a geologic term that is used to describe the appearance of metamorphic rocks. Foliated metamorphic rocks such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure. The pressure is usually related to tectonic plate collisions. Schist is another type of foliated rock that exhibits thin layering of micaceous minerals, once again due to pressure and heat. The difference between these two types of foliated rock lies in the rock from which they were derived. Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks.

What is the term for a type of foliated metamorphic rock?
Schistose Structure metamorphic rocks are known as foliated metamorphic rock.
Limestone is the parent rock of the non foliated metamorphic rock called?
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.

Is a foliated rock easier to break then nonfoliated rock?
Non foliated rocks, such as marble, form from limestone, a common type of sedimentary rock. Foliated rocks form from metamorphic or igneous rocks. Non Foliated rocks are more brittle than foliated rocks making them more susceptible to breakage.
What type of rock is phylitte?
Phyllite is a type of metamorphic rock that forms from the metamorphism of slate. It is characterized by its sheen, fine-grained texture, and foliated structure.
What type of rock can either be foliated or non foliated?
metamorphic
What the difference between a foliated rock and a non-foliated rock?
The Process. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Type of Pressure. If the pressure applied to the recrystallizing rock is unequal, then a foliated rock will form.
What rock type can be extrusive and intrusive?
The type of rock that can be foliated and/or non-foliated is the Igneous rock.
What is the difference between a foliated a non-foliated metamorphic rock?
The Process. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Type of Pressure. If the pressure applied to the recrystallizing rock is unequal, then a foliated rock will form.
What type of rock can be either foilated or non-foliated?
Metamorphic rock can be either foliated or non-foliated. Foliated metamorphic rocks have layered or banded textures, while non-foliated metamorphic rocks lack these layers and have a more uniform appearance. Examples of foliated metamorphic rocks include schist and gneiss, while examples of non-foliated metamorphic rocks include marble and quartzite.
What type of rock has light and dark layers?
foliated.
What is the term for a type of foliated metamorphic rock?
Schistose Structure metamorphic rocks are known as foliated metamorphic rock.
What metamorphic rock type has flat layers?
Foliated rock
Limestone is the parent rock of the non foliated metamorphic rock called?
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.
What is a type of metamorphic rock that has parallel layers?
Foliated rock has parallel layers.
Is scoria foliated or non-foliated?
Scoria is a type of igneous rock that is non-foliated. It forms from rapidly cooling lava and does not exhibit the layers or bands that would be characteristic of foliated rocks.
