The Metamorphic Rock Formed When Granite Undergoes Heat And Pressure

Heat and high pressure can form a metamorphic rock called quartzite.

The metamorphic rock formed when granite undergoes heat and pressure.

In the large outcrop of metamorphic rocks in figure 1 the rocks platy appearance is a result of the process metamorphism. It is striped like a zebra. When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. 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.

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. Foliation is the aligning of. Most of the heat for contact metamorphism is supplied by. In what setting would a metamorphic rock mostly form.

Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz feldspar and mica. What are the agents of metamorphism. A metamorphic rock can be classified according.

A black and white foliated metamorphic rock that forms when granite is put under intense heat and pressure. 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. A type of rock that forms when an existing rock is put under intense heat and or pressure.

Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. 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. Consider how granite changes form. Metamorphic rocks have two classes.

When a rock with flat or elongated minerals is put under immense pressure the minerals line up in layers creating foliation. The standard scientific notation for pressure is expressed in pascals or megapascals 1 pascal is equivalent to 10 bars. Rock cycle it starts as granite then. Metamorphic rocks are formed buried inside the earth s surface on being.

Metamorphic rocks are an important topic in geology. If granite undergoes high temperatures and high pressures at depth within earth what type of rock will be formed. Metamorphic rock metamorphic rock pressure. Limestone changes to marble when it undergoes intense heat and pressure.

Metamorphic rocks metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. Slate is another common metamorphic rock.
