Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble.
Q. How would you describe foliation in metamorphic rocks?
Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer can be as thin as a sheet of paper, or over a meter in thickness. Rocks exhibiting foliation include the standard sequence formed by the prograde metamorphism of mudrocks; slate, phyllite, schist and gneiss.

Q. What describes a foliated rock?
Foliated rock is a special type of metamorphic rock that has distinct, repetitive layers. These layers form as the conditions (heat and pressure) change for each layer of the rock.
Q. What is the type of foliation description?
Foliation, planar arrangement of structural or textural features in any rock type but particularly that resulting from the alignment of constituent mineral grains of a metamorphic rock of the regional variety along straight or wavy planes. …
Q. Which of the following is a foliated metamorphic rock?
Slate, schist, and gneiss are three common foliated metamorphic rocks.
Q. How can you identify a metamorphic rock?
Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, and slate.
Q. How do you describe metamorphic rock?
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
Q. Which rock is best example for metamorphic rock?
Answer
- Anthracite is the best example for metamorphic rock.
- Examples:
- Anthracite- looks shiny and has high percentage of carbon.
- Marble- It is formed from limestone.
- Quartzite- formed from the sand stone. Lime and sand stones are sedimentary rocks.
Q. How can you tell if a rock is a fossil?
Mostly, however, heavy and lightly colored objects are rocks, like flint. Paleontologists also examine the surfaces of potential fossils. If they are smooth and do not have any real texture, they are probably rocks. Even if it is shaped like a bone, if it does not have the right texture then it is probably a rock.
Q. What type of rock is igneous?
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
