Metamorphism of Rocks: Definition, Process & Influencing Factors Metamorphic rocks are the unlucky rocks of the world because they got to their current state after being tortured by intense heat and pressure. In fact, if we look at the word metamorphism, we see that it comes from the word 'morph,' which means to be transformed or changed.

Metamorphic rock Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means change in form. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change.ther minerals, such as olivines, pyroxenes, amphiboles, micas, feldspars, and quartz, may be found in metamorphic rocks, but are not necessarily the result of the process of metamorphism. These minerals formed during the crystallization of igneous rocks.

Metamorphic rock Metamorphic minerals are those that form only at the high temperatures and pressures associated with the process of metamorphism. These minerals, known as index minerals, include sillimanite, kyanite, staurolite, andalusite, and some garnet.owever, all minerals are stable only within certain limits, and the presence of some minerals in metamorphic rocks indicates the approximate temperatures and pressures at which they formed. The change in the particle size of the rock during the process of metamorphism is called recrystallization.

- Pictures of Metamorphic Rocks. Metamorphic rocks are those that form by the effects of heat, pressure and shear upon igneous and sedimentary rocks. Some form during mountain-building by forces of regional metamorphism, others from the heat of igneous intrusions in contact metamorphism.A third category forms by the mechanical forces of fault movements: cataclasis and mylonitization. This is just a starting point to explore the variety in metamorphic rocks.etamorphic rocks are those that form by the effects of heat, pressure and shear upon igneous and sedimentary rocks.

- Metamorphic rocks are the third great class of rocks. These are what happens when sedimentary and igneous rocks become changed, or metamorphosed (changed in form), by conditions underground. The four main agents that metamorphose rocks are heat, pressure, fluids and strain.

The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change.The protolith may be a sedimentary rock, an igneous rock or another older metamorphic rock.etasomatism is the drastic change in the bulk chemical composition of a rock that often occurs during the processes of metamorphism. It is due to the introduction of chemicals from other surrounding rocks. Water may transport these chemicals rapidly over great distances.

metamorphism metamorphism. in geology, process of change in the structure, texture, or composition of rocks rock,aggregation of solid matter composed of one or more of the minerals forming the earth's crust.The scientific study of rocks is called petrology.ontact metamorphism occurs when local rocks are metamorphosed by the heat from an igneous intrusion, such as limestone turning to marble along the contact zone. Some of the changes that occur in the older rock are due simply to the heat radiated from the igneous mass and to the pressures it creates.

Metamorphism Contact metamorphism occurs typically around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock. The area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole.etamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), 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.

Metamorphic Rocks Quick revise. Metamorphic rock is the result of the transformation of a pre-existing rock type in a process called metamorphism, which means change in form. This can occur on sedimentary rock, igneous rock or another older metamorphic rock. Examples of metamorphic rocks are slate and marble.

Metamorphic Rocks Transformation At Work Metamorphic rocks are one of the three types of rock classifications, the other two being igneous and sedimentary. Rocks are classified by the processes under which they were formed.

Metamorphic rock Metamorphic rocks make up a large part of the Earth 's crust and are classified by texture and by chemical and mineral assemblage (metamorphic facies). 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.owever, all minerals are stable only within certain limits, and the presence of some minerals in metamorphic rocks indicates the approximate temperatures and pressures at which they formed. The change in the particle size of the rock during the process of metamorphism is called recrystallization.

- metamorphism: Process of mineralogical and structural (textural) changes of rocks in the solid state in response to physical and chemical conditions which differ from those under which they originated. 1. Mineral assemblages change. 2. Textural Changes (foliations, cleavage, etc). • Physical Conditions = Pressure & Temperature • Chemical Conditions = P H2O, P CO2, fluid solutions w/dissolved solids.

Metamorphism of Rocks: Definition, Process & Influencing Factors 1 Neometamorphism, or neocrystallization, is a metamorphic process that results in the formation of new minerals. This is seen when shale that contains clay minerals change to produce the new mineral garnet.  Metasomatism is the metamorphic process by which the chemical composition of a rock is changed by fluids and heat.

Rocks Metamorphic rocks are sedimentary or igneous rocks that have been transformed by pressure, heat, or the intrusion of fluids. The heat may come from nearby magma or hot water intruding via hot springs. It can also come from subduction, when tectonic forces draw rocks deep beneath the Earth's surface.
