Characteristics Of Metamorphic Rocks

Characteristics of metamorphic rocks. Igneous sedimentary metamorphic igneous are formed from melted rock lava magma that has cooled and solidified when magma cools slowly crystals grow from the molten liquid and a coarse grained rock form.

Characteristics of metamorphic rock cataclastic metamorphism occurs along with the tectonic plate faults where the rocks get rubbed with each other which results in the grain size reduction.

Characteristics of metamorphic rocks. Characteristics of metamorphic rocks 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. As the rock crystallizes or recrystallizes under directed pressure new crystals may grow in some preferred direction sometimes. The recrystallization that takes place does so essentially in the solid state rather than by complete remelting and can be aided by ductile deformation and the presence of interstitial fluids such as water.

This alteration can cause chemical changes or structural modification to the minerals making up the rock. Metamorphism involves the alteration of existing rocks by either excessive heat and pressure or through the chemical action of fluids. Transformation of these rocks are classified as one which could not form non foliated rock and is of low grade.

The two characteristics used to classify metamorphic rocks are foliation and lineation. The types of rocks are. They are crystalline and often have a squashed foliated or banded texture.

Heat and or pressure will cause the elements in the original rock to react and re form. Metamorphic rock metamorphic rock major features. The most common characteristics or structures that are present in metamorphic rocks are foliation and lineation textures and structures.

Metamorphic rocks are often formed by processes deep within the earth that produce new minerals textures and crystal structures. The word metamorphism comes from ancient greek words for change meta and form morph. Characteristics of metamorphic rocks.

The most obvious features of metamorphic rocks are certain planar features that are often termed s surfaces. Metamorphic rocks were once igneous or sedimentary rocks but have been changed metamorphosed as a result of intense heat and or pressure within the earth s crust. The simplest planar features may be primary bedding akin to the layering in sedimentary rocks.

Metamorphic rocks are those formed by other types of rocks that have been exposed to heat pressure and time which change them into a different type of rock. The parallel arrangement of mineral grains forming flaky layers or planes along which the rock that can break easily is called. These characteristics are explained in the following paragraphs.

These are formed when either igneous or sedimentary rocks are changed. These rocks are identified by the presence of certain mineral types and specific textures.
