How Is Metamorphic Rock Formed?

 · Metamorphic rock is formed underground through a process that changes a rock''s molecular structure due to pressure, heat and chemical reactions. A metamorphic rock forms from a parent rock called a protolith. Depending on conditions, a protolith can transform into any metamorphic rock.

Metamorphic Rocks

Metamorphic Rocks. The weight of a mountain creates enough pressure to recrystallize rock, thus creating metamorphic rocks. This program outlines the recrystallization process and the types of rock it can create — from claystone and slate to schist and garnet-bearing gneiss. The relationship of metamorphic rock to plate tectonics is also covered.

Metamorphic rocks

 · Metamorphic rocks have been modified by heat, pressure and chemical processes, usually while buried deep below the Earth''s surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks: Foliated metamorphic rocks such as gneiss, phyllite ...

Metamorphic Rock # 15. Lherzoloite: This is the most typical variety of olivine-rich rocks called peridotites. This rock contains mostly Olivine but smaller amounts of enstatite and diopside. This rock is thought to be the dominant rock in the earth''s upper mantle.

How Are Metamorphic Rocks Formed?

 · While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from pre-existing rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock into a new type of rock, changing the minerals'' composition in the process.

6.4 Metamorphic Environments As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. assemblages.


Metamorphic rocks are classified into two main groups: FOLIATED and NON- FOLIATED. FOLIATED metamorphic rocks have banded or layered appearence. NON-FOLIATED metamorphic rocks do not have band or layers. Name of rock = SLATE. Type of rock = FOLIATED. Parent rock = Shale underwent changes due to heat and pressure.

Schist. Schist is a strongly foliated medium-grade metamorphic rock. It is characterized by an abundance of platy or elongated minerals (micas, chlorite, talc, graphite, amphiboles) in a preferred orientation. Varieties of this rock type share similarities in appearance (schistosity) but may be highly variable in composition.

Origin, Texture, and Classification of Metamorphic Rocks

Metamorphic rocks are igneous, sedimentary, or other metamorphic rocks whose texture and composition has been changed by metamorphism. Metamorphism occurs as a response to changes in the physical or chemical environment of any pre-existing rock,

Metamorphic Minerals | National Museum Wales

Within each of these facies a rock of a particular composition (e.g. basic igneous rock or limestone) will crystallize a predictable suite of metamorphic minerals. Metamorphic rocks therefore provide a record of the pressures and temperatures that have affected the rocks in a given district, from which information such as their depth of burial and their tectonic history can be deduced.

Metamorphic Rock | Physical Geography

Metamorphic Rock. 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. Metamorphic rocks may change so much that they may not resemble the original rock. Any type of rock—igneous, sedimentary, or metamorphic—can become a metamorphic rock.

Metamorphic Rock Types: Pictures and Descriptions

 · Schist is a metamorphic rock that comes in almost infinite variety, but its main characteristic is hinted at in its name: Schist comes from the ancient Greek for "split," through Latin and French. It is formed by dynamic metamorphism at high temperatures and high pressures that aligns the grains of mica, hornblende, and other flat or elongated minerals into thin layers, or foliation.

Metamorphic Rock

Metamorphic rocks are defined as rocks derived from a primary rock (protolith) by chemical and physical processes that change the minerals and the structure of rock. The protolith can be of sedimentary, metamorphic or igneous origin.

Characteristics of Metamorphic Rocks

Characteristics of Metamorphic Rocks. One of the oldest types of rocks on our planet, metamorphic rocks are mainly formed due to changes in the parameters of temperature and pressure, which act on the parent material. Their study provides us with important data regarding formation of the Earth and the past geological environment.
