The Metamorphic Rock Formed When Granite Undergoes Heat And Poressure

Both can form from the other type.

The metamorphic rock formed when granite undergoes heat and poressure.

Metamorphic forma s a result of intense heat and pressure. These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks. The granitic rock in migmatite probably originated from partial melting of some of the metamorphic rock though in some migmatites the granite may have intruded the rock from deeper in the crust. They may be formed simply by being deep beneath the earth s surface subjected to high temperatures and the great pressure of the rock layers above it.

They are also formed when rock is heated by the intrusion of hot molten rock called magma from the earth s interior. Metamorphic rocks have two classes. Metamorphic rocks are formed buried inside the earth s surface on being subjected to high temperatures and pressures of the rock layers above it. They differ in the way they form.

Sedimentary form as a result of cementation and compaction. Foliation is the aligning of elongated or platy minerals like hornblende or mica perpendicular to the direction of pressure that is applied. Slate is another common metamorphic rock that forms from shale. 1 regional metamorphism which affects a large area.

When a rock with flat or elongated minerals is put under immense pressure the minerals line up in layers creating foliation. They are formed when igneous sedimentary or other metamorphic rocks undergo physical transformations under very great heat pressure or due to other natural agencies. Marble marble is a metamorphic rock made up of granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Metamorphic rocks change when exposed to even more heat and pressure.

According to geology the term metamorphic is denoted to the rock that undergoes metamorphism. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. Metamorphic rocks form from the exposure to intense heat and pressure two types of metamorphism are.

Both formed as a result of the rock cycle. In migmatite you can see metamorphic rock that has reached the limits of metamorphism and begun transitioning into the igneous stage of the rock cycle by melting to form magma. Metamorphic rocks are an important topic in geology. Metamorphic rocks metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure.

They can form from tectonic processes such as continental collisions which cause horizontal pressure friction and distortion.
