There should be plenty of foliated metamorphic rocks in Pennsylvania, due to the erosion of the Appalachian Mountains. Another source for foliated metamorphic rocks in Pennsylvania would be from glacial drift dropped from previous glacial episodes which were torn and transported from areas in Canada.

What are the characteristics of foliated and non-foliated metamorphic rocks?

Foliated metamorphic rocks have a layered or banded appearance due to alignment of mineral grains, exhibit strong cleavage, and are formed under directed pressure. Non-foliated metamorphic rocks do not have a layered structure, show more equidimensional mineral grains, lack cleavage, and are typically formed under contact metamorphism.


What are the two categories of metamorphic rocks?

Metamorphic rocks can be categorized into two main categories: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while non-foliated metamorphic rocks lack this layered structure.


Metamorphic rocks are classified into two groups?

Metamorphic rocks are classified into two main groups: foliated and non-foliated. Foliated rocks have a layered or banded appearance due to the alignment of mineral grains during metamorphism, while non-foliated rocks lack this layered structure and typically consist of interlocking crystals.


What are the classes of metamorphic rocks?

The classes of metamorphic rocks include foliated rocks, which have a layered or banded appearance due to the alignment of minerals, and non-foliated rocks, which lack a layered structure. Foliated rocks include slate, schist, and gneiss, while non-foliated rocks include marble and quartzite.


What do foliated and non-foliated rocks have in common?

Foliated and non-foliated rocks are both types of metamorphic rocks formed from the transformation of pre-existing rocks under heat and pressure. However, they differ in their texture and appearance, with foliated rocks having a banded or layered structure due to the alignment of mineral grains, while non-foliated rocks lack this banding and have a more uniform, random grain orientation.

How are foliated metamorphic rocks different from nonfoliated metamorphic rocks?

Foliated are made of interlocking crystals, non-foliated are not.


What classification of metamorphic rocks would include whether they are?

Foliated or non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this feature.


What determines whether a metamorphic is foliated or non- foliated?

The presence of aligned minerals in the rock determines if it is foliated or non-foliated. Foliated metamorphic rocks have minerals that are arranged in layers or bands, while non-foliated rocks do not show any preferred orientation of minerals. The amount of pressure and temperature the rock experiences during metamorphism also influences whether it will develop a foliated or non-foliated texture.


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.


How do you tell between foliated and non foliated?

Well foliated rocks have layers and non foliated does not have layers.


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.
