What is the metamorphism of limestone?
What is the metamorphism of limestone?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
What type of metamorphism is responsible for the limestone alteration?
When hot water contributes to changes in rocks, including mineral alteration and formation of veins, it is known as hydrothermal alteration. A special type of metasomatism takes place where a hot pluton intrudes into carbonate rock such as limestone.
What is an example of regional metamorphism?
Regionally metamorphosed rocks usually have a squashed, or foliated appearance – examples include slate, schist and gneiss (pronounced “nice”), formed by metamorphism of mudstones, and also marble which is formed by metamorphism of limestone.
What kind of rocks are produced by cataclastic metamorphism?
Cataclastic metamorphism is generally localized along fault planes (areas of detachment where rocks slide past one another). Cataclastic Metamorphism produces sheared, highly deformed rocks called mylonites.
What happens to metamorphic rocks at low temperature?
Rocks metamorphosed at low temperature may change only very slowly, and some changes may not go to completion. Rocks that form at high temperatures generally do not have the same problems. However, there are many kinds of metamorphic rocks, and some of them are more chemically reactive than others.
Which is an example of a regional metamorphism?
Regional Metamorphism: It takes place due to the internal mountains building movements which exert great pressure on the rocks. Thus the entire shape of the rocks is changed. For example, shale becomes slate which then changes into schist.
What makes a rock different from a limestone rock?
When we have to compare Coal vs Limestone, the texture, color and appearance plays an important role in determining the type of rock.
