Marble Is An Example Of Metamorphic Rock Changing Into

Metamorphism can be progressive or regressive.

Marble is an example of metamorphic rock changing into.

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. Igneous rocks igneous rocks are formed by volcanoes. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Metamorphic rocks are often made from other types of rock.

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. Slate is another common metamorphic rock that forms from shale. Other examples of metamorphic rocks include marble anthracite soapstone and schist.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Metamorphic rocks are those produced by the evolution of a rock above was subjected to an atmosphere energy very different from the formation for example more hot or cold or by a significant change of pressure. Another example of a changing into a is limestone changing into because of extreme heat and pressure on the limestone deep beneath the surface.

The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing metamorphic rock. When a volcano erupts. Learn more about metamorphic rocks here. Sedimentary rock non foliated metamorphic rock marble.

The table below shows examples of common metamorphic rocks. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. For example shale a sedimentary rock can be changed or metamorphosed into a metamorphic rock such as slate or gneiss. Remember these rocks are formed under extreme heat and pressure.

Metamorphic rocks are formed from other rocks that are changed because of heat or pressure.
