Metamorphic Rocks National Geographic Society

10/10/2019· In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed

metamorphic rock Definition, Formation, & Facts Britannica

Metamorphic rock, any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure, and mechanical stress, and the addition or subtraction of chemical components. The preexisting rocks may be igneous, sedimentary, or other metamorphic rocks.

Metamorphic rock Wikipedia

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". 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 rock Simple English Wikipedia, the free

A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change. The original rock may be sedimentary rock, igneous rock or another older

Metamorphic Rocks Geology

A metamorphic rock used to be some other type of rock, but it was changed inside the Earth to become a new type of rock. The word metamorphism comes from ancient Greek words for “change” (meta) and “form” (morph). The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are

Metamorphic Rocks Types of Metamorphic Rocks

Metamorphic word comes from the Greek words “meta” and “morph”. Meta means change and morph means form. These rocks have changed form due to heat and pressure. Metamorphic rocks make up a large part of the Earth's crust. They are classified by texture and properties. They are formed when other types of rock layers above them are subjected to high temperatures and pressure. Metamorphic

Metamorphic rock Metamorphic rock Metamorphic reactions: A very simple mineralogical system and its response to changing pressure and temperature provide a good illustration of what occurs in metamorphism. An uncomplicated sediment at Earth’s surface, a mixture of the clay mineral kaolinite [Al4Si4O10(OH)8] and the mineral quartz (SiO2), provides a good example.

Metamorphism Wikipedia

Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. The chemical components and crystal structures of the minerals making up the rock may change even
