Marble Is An Example Of What Type Of Metamorphic Rock

Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.

Marble is an example of what type of metamorphic rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. There are hundreds of metamorphic rocks across the face of the earth with different compositions and textures. Examples of metamorphic rocks. Image will be uploaded soon types of metamorphic rocks.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Metamorphic rocks are formed form pre existing rocks through the process of metamorphism. Common examples of metamorphic rocks are gneiss schist marble slateetc.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. 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. Other examples include quartzite hornfels and novaculite.

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. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Metamorphic rocks rarely contain fossils.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Slate is another common metamorphic rock that forms from shale. Learn more about metamorphic rocks here. Metamorphic rocks do not melt but the chemicals they contain may change their forms or crystal shapes.

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. Examples of metamorphic rocks. In this hand specimen of vermont marble the crystals are small. Metamorphic rocks can become banded or foliated the arrangement of minerals that gives the rock a striped appearance.

Remember these rocks are formed under extreme heat and pressure. The table below shows examples of common metamorphic rocks. Slate granite gneiss and biotite schist are strongly banded and foliated. Marble is commonly used for sculpture and as a building material.

Metamorphic rocks started out as some other type of rock but have been substantially changed from their original igneous sedimentary or earlier metamorphic form.
