Marble is an example of metamorphic rock changing into.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Slate is another common metamorphic rock that forms from shale. Metamorphism can be progressive or regressive. Igneous rocks igneous rocks are formed by volcanoes.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. As per wikipedia metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form the original rock protolith is subjected to heat temperatures greater than 150 to 200 c and pressure 1500 bars causing profound physical and or chemical change. 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. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. For example shale a sedimentary rock can be changed or metamorphosed into a metamorphic rock such as slate or gneiss. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. The table below shows examples of common metamorphic rocks.

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. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Another example of a changing into a is limestone changing into because of extreme heat and pressure on the limestone deep beneath the surface.

Remember these rocks are formed under extreme heat and pressure. When a volcano erupts. Metamorphic rocks are often made from other types of rock. Other examples of metamorphic rocks include marble anthracite soapstone and schist.
