The main way metamorphic rocks are classified is by the presence or absence of foliation. Foliated metamorphic rocks are distinguished by the type of foliation they exhibit. Types of foliation textures, include: slaty, phyllitic, schistose, and gneissi.

layers.
Do foliated rocks have layers?
Non-foliated metamorphic rocks generally do not have distinct layering.
Why can you see layers in foliated rocks but not in nonfoliated rocks?
Because layers from foliated rocks came from the same direction and nonfoliated rocks came from several directions
Is Rhyolite foliated or non-foliated?
Neither. Foliation is a term used in assesing metamorphic rocks, not igneous rocks such as rhyolite.
What is a kind of non foliated metamorphic rock?
Metamorphic rocks are rocks that have their grains arranged in parallel layers or bands. Foliated rocks are formed under great pressure and heat, and when they cool they have a banded grain pattern.
What is foliated rocks distinguished by?
layers.
What Foliated rocks are distinguished by .?
The alignment of minerals to form a planer fabric. This may give the rock a banded appearance.
What are the characteristics of foliated and non-foliated metamorphic rocks?
Foliated rocks are metamorphic rocks that look like they have layers or the appearance of layers. Non-foliated rocks are metamorphic rocks without any foliation.
Do foliated rocks have layers?
Non-foliated metamorphic rocks generally do not have distinct layering.
How are foliated metamorphic rocks different from nonfoliated metamorphic rocks?
Foliated are made of interlocking crystals, non-foliated are not.
What are the two categories of metamorphic rocks?
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
What are foliated metamorphic rocks?
Foliated rocks have layers in them. We often refer to the layers as Banding.
What rocks have foliated structure?
"Foliated" rocks are usually metamorphic rocks like phyllite, slate, schist, and gneiss.
When metamorphic rock has banded texture with minerals grains that are arranged in layers it is called?
Metamorphic rocks with a layered or banded look are referred to as foliated.
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
How do you tell between foliated and non foliated?
Well foliated rocks have layers and non foliated does not have layers.
