Marble is an example of metamorphic rock changing into.

Other examples of metamorphic rocks include marble anthracite soapstone and schist. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. They are not made from molten rock rocks that do melt form igneous rocks instead.

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 table below shows examples of common metamorphic rocks. Sedimentary rock non foliated metamorphic rock marble. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.

Igneous rocks igneous rocks are formed by volcanoes. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Remember these rocks are formed under extreme heat and pressure. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.

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. 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. Metamorphic rocks are often made from other types of rock. For example shale a sedimentary rock can be changed or metamorphosed into a metamorphic rock such as slate or gneiss.

When a volcano erupts. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. 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.

Metamorphism can be progressive or regressive.
