There are hundreds of metamorphic rocks across the face of the earth with different compositions and textures.
Marble is an example of what type of metamorphic rock.
Metamorphic rocks are formed form pre existing rocks through the process of metamorphism.
The best way of learning their various types is by handling and.
Marble is commonly used for sculpture and as a building material.
Common examples of metamorphic rocks are gneiss schist marble slateetc.
Metamorphic rocks rarely contain fossils.
Metamorphic rocks form when rocks are subjected to high heat high pressure hot mineral rich fluids or more commonly some combination of these factors.
The extensively known example of non foliated metamorphic rock is a marble.
Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance.
Examples of metamorphic rocks.
Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.
Pictures and brief descriptions of some common types.
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Remember these rocks are formed under extreme heat and pressure.
In this hand specimen of vermont marble the crystals are small.
This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.
Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.
Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.
The metamorphic rocks are foliated and non foliated as well.
Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
Slate is another common metamorphic rock that forms from shale.
Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window.
The table below shows examples of common metamorphic rocks.
Metamorphic rocks started out as some other type of rock but have been substantially changed from their original igneous sedimentary or earlier metamorphic form.
Other examples include quartzite hornfels and novaculite.
Metamorphic rocks do not melt but the chemicals they contain may change their forms or crystal shapes.
Image will be uploaded soon types of metamorphic rocks.
Metamorphic rocks can become banded or foliated the arrangement of minerals that gives the rock a striped appearance.
Slate granite gneiss and biotite schist are strongly banded and foliated.
