The Metamorphic Rock Formed When Granite Undergoes Heat And Pressure

A metamorphic rock can be classified according.

The metamorphic rock formed when granite undergoes heat and pressure. Metamorphic rock metamorphic rock pressure. Rock cycle it starts as granite then. If granite undergoes high temperatures and high pressures at depth within earth what type of rock will be formed. Metamorphic rocks are an important topic in geology.

Limestone changes to marble when it undergoes intense heat and pressure. When a rock with flat or elongated minerals is put under immense pressure the minerals line up in layers creating foliation. Foliation is the aligning of. Heat and high pressure can form a metamorphic rock called quartzite.

Magma hardens to form an igneous rock. The pressure experienced by a rock during metamorphism is due primarily to the weight of the overlying rocks i e lithostatic pressure and is generally reported in units of bars or kilobars. What are the agents of metamorphism. A type of rock that forms when an existing rock is put under intense heat and or pressure.

When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. It is usually composed primarily of the minerals quartz feldspar and mica. Metamorphic rocks have two classes. A black and white foliated metamorphic rock that forms when granite is put under intense heat and pressure.

According to geology the term metamorphic is denoted to the rock that undergoes metamorphism. Slate is another common metamorphic rock. 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. They are formed when igneous sedimentary or other metamorphic rocks undergo physical transformations under very great heat pressure or due to other natural agencies.

These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Metamorphism is the addition of heat and or pressure to existing rocks which causes them to change physically and or chemically so that they become a new rock. It is striped like a zebra.

The standard scientific notation for pressure is expressed in pascals or megapascals 1 pascal is equivalent to 10 bars. Some form during mountain building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism. Metamorphic rocks are formed buried inside the earth s surface on being. In the large outcrop of metamorphic rocks in figure 1 the rocks platy appearance is a result of the process metamorphism.

Metamorphic rocks metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. Most of the heat for contact metamorphism is supplied by.
